John Knight, President, Yorkshire Geological Society: Carboniferous stratotypes of substages in the Visean-Namurian succession of Northern England- Introduction and summary of the Carboniferous Subcommission visit, October 2015
The visit of members of the IUGS Subcommission on Carboniferous Stratigraphy (SCCS), organised by the Society in October 2015, to visit stratotype sections in Northern England, was prompted by a request from Dr Barry Richards, Chairman of the Subcommission in July 2014.  The Society was pleased to comply as the organising entity although the broad scope of the task was not at first evident.  The location of relevant stratotype sections is generally well-known and most recently was summarised in the Geological Society Special report No. 26 (A Revised Correlation of Carboniferous Rocks in the British Isles, 2011: Waters C.N. et al.). 
However, the documentation on which the stratotypes were formally established is the field guide prepared under the editorship of Dr Bill Ramsbottom for the 1981 visit of the SCCS to the UK (Ramsbottom W.H.C. [ed.] 1981); this document was never formally published.  A number of Society members have made clean copies of the original field guide available and the document is now available on the Society website: http://www.yorksgeolsoc.org.uk/Stratotypes/Ramsbottom1981.pdf).  In order to organise a reasonable visit timetable of four days, the visit programme was designed around visits to the stratotypes of the two top Dinantian substages (Asbian and Brigantian) and to those of six Namurian substages (Pendleian, Chokierian, Alportian, Kinderscoutian, Marsdenian, Yeadonian; the stratotype of the Arnsbergian is in Ireland).
More or less simultaneously with the identification of the boundary stratotypes in the late 1970s, each one of the locations was covered by designation as a Site of Special Scientific Interest (SSSI).  Under present legislation Natural England is the statutory body responsible for protection and conservation of the sites.  For planning access to the various locations, it was necessary in the first place to identify the relevant officer of Natural England responsible for each site and also the owners of the site.  Initial inspection of the sites indicated that some had become heavily overgrown and possibly had not been visited since designation, over 30 years earlier.  
Significant site clearance effort was required on five locations (Pendleian, Chokierian, Alportian, Kinderscoutian, Marsdenian stratotypes).  The scope of clearance work had to be agreed with Natural England and site owners and specific approval obtained for a formal visit of a significant professional group and for any collecting.  A general protocol for site clearance was established with Natural England.  A considerable number of Society members, with assistance from other local groups, helped clear exposures in the period July – September 2015 prior to the visit of SCCS members in October in which they were accompanied by considerable numbers of Society members.
The present meeting is an opportunity to thank the officers of Natural England, site owners, those local groups who have assisted site preparation and those Society members who made the visit successful.   It is also the opportunity to develop a strategy to build on the effort to clear these sites thus providing the possibility of further research, taking advantage of the good relationships which have been developed for access to these sites.  This meeting will include a final discussion session, with a brief presentation from Natural England, in which it is hoped to explore how this Society can encourage a further research programme to update published documentation of these stratotypes and also contribute directly to ensuring these important reference sections remain in a state which will allow further research.

Dr Nick Riley MBE, C. Geol., FGS, Director, Carboniferous Ltd., Nottingham, UK.  e-mail carboniferouslimited@gmail.com: The Carboniferous regional stage stratotypes of Northern England; their background & purpose. After four decades, how do they stack up?
The  regional stages of the British Isles  (now considered as regional substages in global classification),  were erected & defined by George et al. (1976) and  Ramsbottom et al. (1978), for the Dinantian and Namurian  series respectively.  In the Dinantian and Namurian all but three of these stratotypes are located in Northern England. Each stage  has a basal boundary defined at a specific point  in a marine rock section (stratotype). The top of each stage is therefore defined by the basal boundary of the overlying stage. Stages are  chronostratigraphical (time) units, not biostratigraphical .
The philosophy behind defining their basal boundaries was very much influenced by Ramsbottom’s (1973 & 1977)  pioneering attempts at recognising major cycles of eustatic  transgression (“mesothems”) and regression in the UK Carboniferous succession and beyond. In effect the stages were defined by what we would now term sequence stratigraphical boundaries. Each transgression introduced new marine faunal assemblages, which provided the biostratigraphical means for recognition and correlation of strata within each stage. The base of the stage being taken at the first  lithological (often coincident with a lithostratigraphical boundary) change below the first entry of such faunas.
This approach brought some major breakthroughs, such as demonstrating that Vaughan’s (1905)   and Garwood’s (1913) Dinantian coral/brachiopod zonations were based on successions containing major sequence breaks. In an attempt to avoid such breaks, Dinantian stratotype sections were located in thick successions, which were thought to be complete. Micropalaeontology was still developing in the UK, hence much of the emphasis was on erecting stratotypes where macrofossils, especially corals and brachiopods in the Dinantian , and ammonoids in the Namurian occurred. This approach gave some continuity with the rich legacy of published work that predated the stratotypes. All the Dinantian stratotypes were given names derived from the local or regional geography within which the stratotypes were located. In the Namurian this was partly the case, however some pre-existing names were imported from the near-continent, in order to maintain continuity with pre-existing nomenclature. 
Forty years on since George et al. (1976) how do the stratotypes stand up to modern scrutiny?  The George et al. (1976) reports of the first stratigraphical appearance of the foraminferan Eoparastafella and the coral  Dibunophyllum have not been repeated, or verified, at the Chadian & Asbian stratotypes respectively. Our understanding of sequence stratigraphy, sedimentology,   biostratigraphy/palaeoecology/biogeography & global correlation is now much more robust than in the 1970’s and new insights are emerging with chemostratigraphy. Is it wise to have any marine chronostratigraphical stratotypes based on carbonate ramp/platform locations or fluvio-deltaic settings, such as in the Dinantian, and  Namurian respectively. These settings inevitably have significant breaks in sequence, some of which were missed by George et al. (1976). Would relocating the stratotypes  to hemi-pelagic sequence settings be more appropriate? Whatever the decision,  a “laissez-faire” response is not helpful, indeed, it is  damaging to scientific progress. Chronostratigraphical stratotypes should be defined in the most complete, resolvable  (in a time sense),  rock  sections available. They should be the key, defendable,  reference sections for  national and international standards in geological time.

14.50-15.20. Dr  Markus Aretz, GET (Geosciences Environnement Toulouse), Université Paul Sabatier: Observatoire Midi-Pyrénées, Toulouse, France:  Asbian and Brigantian
The Asbian and Brigantian substages are not only the late Viséan stratigraphic units of the British Isles, but they have also been used in other countries and facies realms. Despite this apparent international recognition and acceptance, there are still remaining questions of how robust these stratigraphic units really are and if there are distinct Asbian or Brigantian faunas, which can be used to characterise specific time slices.
Diversity largely increases during Asbian times, and this is often used to differentiate an early Asbian fauna from a late Asbian fauna. But when taking a look on the Asbian stratotype section at Little Asby Scar, the differences between faunas become less evident. Taxa normally associated with the late Asbian appear near the Holkerian/Asbian boundary, which may partly result from the (unusual) low thickness of lower Asbian strata in the stratotype. However, early and late Asbian faunas are often found outside the British Isles, even in regions using different stratigraphic names like the Warnantian in Belgium.
A typical fauna enables the distinction of the Brigantian substage as an entity, which e.g. is called late Warnantian in Belgium. However, the attempt to differentiate it into smaller portions is not as easy as often thought despite the existence of potential markers. The occurrence of fauna is largely facies-controlled (e.g. ‘Yoredale cycles’) and many first appearance dates remain rather obscure. Detailed studies of the last decade show that typical markers occur lower in the stratigraphic column than previously thought. This is well illustrated by the stratotype section at Janny Wood, where the boundary might be placed too high.
The definition of the base of the Serpukhovian stage will largely influence the use of the Brigantian substage. The proposed marker appears deep in the Brigantian and thus an important part today attributed to the Brigantian and thus Visean may become Serpukhovian. Thus is there still a need to subdivide the Brigantian or should a new substage be defined for the current late Brigantian?
Dr Duncan McLean and David Bodman, MB Stratigraphy Limited, 11 Clement Street, Sheffield, S9 5EA: Progress on the palynology of the Pennine Carboniferous stratotype sections
For historical and economic reasons, the Namurian probably represents the least understood part of Euramerican Carboniferous miospore biostratigraphy. The interval is characterised by miospore assemblages with high dominance and high diversity. This provides a challenge for appropriate data acquisition and development of an accurate knowledge of the stratigraphical ranges of many morphologically distinctive but rare species. Further, the high diversity involves a large number of undescribed forms at both generic and specific taxonomic levels.
A programme of palynological sampling and analysis of the recently revitalised Pennine Carboniferous stratotypes is ongoing. The Asbian stratotype at Little Asby Scar, Cumbria consists of a limestone sequence unsuitable for palynology and has not been included. The remaining sections provide important stratigraphical controls on the ranges of key miospore taxa and the definitions of European miospore biozones.
Stratotype sections for the Pendleian in Light Clough, Lancashire, the Chokierian in Stonehead Beck, Yorkshire, and the Yeadonian at Orchard Farm, Staffordshire have all been fully logged and sampled. Preliminary results indicate excellent miospore recovery. The Kinderscoutian stratotype section at Samlesbury Bottoms, Lancashire has yet to be logged and sampled.
Preliminary sampling of late Asbian siltstones in the Brigantian stratotype section at Janny Wood, Cumbria provided good palynological material. This indicates that the base of the vetustus-fracta miospore biozone lies within the late Asbian between the Robinson Limestone Member and the Birkdale Limestone Member. The section is to be resampled along with sedimentological logging of the clastics. The Alportian stratotype section in Blake Brook, Staffordshire has been fully logged and sampled. Preliminary results indicate excellent miospore recovery. Abundances of Crassispora kosankei through the section indicate that the base of the epibole of this species is not within the Alportian, as previously reported, but earlier. This interpretation is in line with records from Namurian sections in the southern North Sea. The section provides accurate controls on the range limits of several critical miospore species which provide subdivision of the late Chokierian to early Kinderscoutian sequence.
The Marsdenian stratotype in Park Clough, Yorkshire is weathered and penetrated by tree roots and is unsuitable for palynology. A comparable section about 50m upstream exposes the top of the Gracilis Marine Band and a section up to the second Bilinguis Marine Band. Reconnaissance samples from here provided good miospore recovery. Unfortunately, as with the classic, correlative section at Pule Hill, the base of the Gracilis Marine Band is not exposed and so the section is unsuitable as a parastratotype.

President’s Word

When this Circular reaches you there will still be time to submit your questionnaire on your views on the direction of the Society.  Please make the effort to ensure that you submit your views.  It is apparent from the various meetings of Council that there are always changes taking place gradually in the running of the Society, sometimes due to change in the  individuals who fulfil the various posts of officers of the Society, sometimes by design and occasionally by default.  However, through its committees, Council is continually endeavouring to review how it can improve the service to members, fulfil our obligations as a charity and maintain the scientific profile of the Society.  We urgently need new blood on Council.  Please consider if you can contribute to a robust future for the Society by joining Council.  If you are interested to know what this involves please feel free to contact me, or Paul Hildreth, the General Secretary (e-mail addresses and telephone numbers in the information section of the Circular).
This Circular includes the details for our meeting which reports on the field excursion organised by the Society to host visitors from the IUGS Subcommission on Carboniferous Stratigraphy to stratotypes of Visean-Namurian substages in Northern England.  This was an opportunity for the Society to contribute directly to scientific interpretation.  This also opens the opportunity for the Society to take a lead in programmes of scientific investigation- this is a role which has been undertaken by the Society on numerous occasions in the past.  Recent deliberations of Council recognise that this is an important part of our Society objectives. 
You may wish to note the agreement in principle by Council that the Society’s Fearnsides Prize, for many years awarded by Council for field work by undergraduates or early career geologists,  is to be renamed the Fearnsides Award, with the intent that the award will be become a grant available as a support to research programmes.  At first sight this may seem to be a minor change but in fact a commitment to support research projects by award to approved proposals, as opposed to recognising previously completed work.  It is important that the Society maintains a scientific profile, in conjunction with maintaining a respected peer-reviewed journal, without prejudicing our parallel outreach and educational activities. 
It will be welcome that members express their views on the profile and emphasis of Society activities.  The survey questionnaire is an important part of this, but please take any opportunity to discuss this with me or any other members of Council.
John Knight, President

Yorkshire Rocks and Landscape – the popular YGS Field Guide, Third Edition

Yorkshire, famed for its scenic beauty and its rich industrial heritage, contains some of the most interesting geology and scenery in England , from the moors to the coast, including the Yorkshire Dales and North York Moors national parks. The influence of the geology on the landscape and on the industrial development in the region is profound.  

This book is a stimulating field guide to twenty-one locations selected to give comprehensive coverage of the geology, minerals, rocks, fossils and landforms of the area. Excursions vary from easy half–day walks to longer outings. Some are in moorland areas such as the Craven Inliers and the Pennines; others cover the Dinosaur Coast, famous for its rugged beauty and natural history, and coalfields adjacent to the major cities.

  Aimed at beginners and more experienced geologists, the book includes a general introduction to the area’s geological history, detailed location maps, a full glossary of terms, and details of local museums.

  Yorkshire Rocks and Landscape will be used and enjoyed by all those interested in the geology and natural heritage of this exciting and diverse region, especially the links between landscape and the underlying geology,

 About the Authors: The field guide, edited by Drs. Colin Scrutton and John Powell, has contributions from knowledgeable academics, professional geologists and dedicated amateurs, many of them members of the Yorkshire Geological Society. Together in this book they provide the most up-to-date and authoritative guide to the geology of Yorkshire and surrounding areas currently available.  

Published: September 2006; 224 pp, 22 figures.  Price 9.99, plus postage and packing 3.35. Cheques should be made payable to "Yorkshire Geological Society".  Please send your order to: Dr Claire Dashwood, British Geological Survey, Keyworth, Nottingham, NG12 5GG. E-mail: cfoster@bgs.ac.uk

  Also available at indoor meetings of the Yorkshire Geological Society (no p&p) and from selected bookshops.

Important Notice to Members and others:Short Communications: Proceedings and Circular/Web Site

Rapid publication of short papers is common amongst journals, particularly those published weekly, monthly or bi-monthly, as a way of disseminating information quickly on topical or contentious issues, exceptional new discoveries or major developments.   Given its publication schedule, the adoption of such a publication strategy is not appropriate for the Proceedings.  Nevertheless, as a way of encouraging the membership to make more use of the Proceedings, and for that matter the Society’s other vehicles for publication, the Circular and web site, Council would welcome more short communications. Short communications submitted to the Proceedings might include anything for which it would be worth having a permanent published record, for example descriptions of new and/or temporary exposures.  Those intended for the Circular or web site could include more topical or newsworthy items, including brief reports of field meetings, new fossil/mineral occurrences, photographs of interesting geological features with a brief description or the work of RIGS groups. Short communications to the Proceedings should not exceed two published pages, approximately 2,000 words (or equivalents including figures) and will be subject to the normal review and editorial procedures, although a Summary will not be necessary. Please send your contributions in the usual manner to the Editors (see ‘Instructions to Authors’ in the PYGS as a general guideline).

For the A5 format of the Circular (and web site), contributions should be 300-400 words, but can include colour photographs and figures; these will also be subject to editorial review. These items should be sent to the Circular Editor in the first instance (see back page of the Circular for details).
