Afternoon Session: Longer Illustrated talks on the geology and landscape of Yorkshire’s two National Parks by Tony Waltham (Yorkshire Dales) and John Powell (North York Moors).

Abstracts of the two main afternoon talks:

Geology and Landscapes of the Yorkshire Dales: Tony Waltham (formerly Lecturer in Engineering Geology, University of Nottingham - now retired)

The splendours of the Yorkshire Dales National Park owe much to a fine rock sequence. Gritstones form the fells above Swaledale and also the tors of Brimham Rocks. Repetitive sequences of the Yoredale rocks define the terraced hillsides of Wensleydale and were host to most of the mineral ores worked in years gone by. Then the Great Scar Limestone forms the magnificent karst landscapes in and around the Craven Dales.
How many Quaternary glaciations we are still not sure, but the last one left behind some textbook landforms. Besides trimming the deep glaciated troughs that are the dales, ice shaped the great drumlin field at Ribblehead, left the infamous erratics at Norber, and heaped up the moraines that dammed by-gone lakes along the dale floors. And erosion by the ice sheets was so critical in the evolution of the Dales’ signature limestone pavements that the limestone landscape is best described as a glaciokarst.
The limestone country of the southern Dales offers textbook landscapes of rock dissolution, sinkholes (or dolines, whichever you prefer, and including shakeholes), disappearing streams and underground drainage. The surface karst is dominated by the pavements on bare rock and by the shakeholes in any cover of till, and also bears the mark of meltwater around and beneath the Quaternary glaciers; Malham Cove and Gordale Scar are icons of the Dales, but there is still debate about just how they were formed.
Out of sight to all but a few, the Dales’ caves are a hugely important component of the geomorphology. The cave streamways step down through the bedding planes and joints in the limestone, and intersect abandoned passages half-choked with clastic sediment and beautifully decorated with stalagmites. These provide a unique record of erosional and climatic events stretching back far into the Quaternary; they tell of multiple glaciations and valley deepening, but there is still a lot more to learn from them.

Geology and landscape of the North York Moors National Park as reflected in the local Jurassic building stones: John Powell, Honorary Research Associate, British Geological Survey
The talk will highlight the geological and landscape evolution of the North York Moors National Park and the use of its varied Jurassic bedrock as local building stones that give the villages, towns and monumental buildings their diverse character. The National Park represents part of the Jurassic Cleveland Basin, the site of predominantly shallow marine and fluvio-deltaic sedimentation from 201-145 million years ago that was subsequently gently folded and uplifted in Tertiary times (about 50 million years ago). During the last ice-age (about 25,000 thousand years ago) Quaternary ice-sheets scoured the eastern and western margins of the moors depositing a wide range of glacial deposits and sculpting much of the incised landscape that we see today. The geological history of this remarkable region will be linked to its building stones, the focus of a recent study for English Heritage - the ‘Strategic Stone Study’* - aimed at increasing our knowledge of the variability of building stone as an aid to conservation.

Yorkshire Geology Month 2014

Yorkshire Geology Month 2014 will take place from mid-May to the end of June and will consist of a varied programme of activities aimed at all levels of interest and experience.  Its main aim however is to have a “Heineken effect” and, to paraphrase, “reach those parts that other events cannot reach” by targeting sites already used by the general public for other activities and offering additional geological experiences.  So far the programme includes input at the RSPB reserve at Bempton Cliffs, a Lancashire Wildlife Trust SSSI, Roundhay Park, Scunthorpe Museum and the Rotunda Museum (Scarborough).
There will also be more specialised activities, mainly following the field trip format. The Society’s May meeting at the National Coalmining Museum on Saturday 3rd May - see able - will begin with a morning dedicated to the launch of Yorkshire Geology Month 2014.  A short talk on the aims of YGM and the scope of the programme offered will invite the public to visit stands provided by the participating geology groups and societies.  These may have displays, activities, information leaflets or simply have someone available to talk to.  
Exciting developments that may provide a legacy of YGM 2014 include preparations for holding a meeting in North Lincolnshire during the YGM period with the aim of forming a new geology group, and the involvement for the first time of the Royal Society for the Protection of Birds (at their Bempton Reserve).

New Society Award to mark the Society’s 175th anniversary year: the Dr W.S. Bisat FRS Medal

At the December 2013 AGM it was announced that the Council had agreed to accept an offer of an anonymous donation to fund the establishment of an additional Society Award to mark the Society’s 175th anniversary year. This will take the form of a Medal, to be awarded not more frequently than once every two years, to be named in honour of Dr William S. Bisat, a member of the Society from 1909 to his death in 1973 and the President for 1938-40.  Dr Bisat, one of the very few amateur scientists to be elected a Fellow of the Royal Society in the 20th century, was by profession a civil engineer, rising from a school-leaver Junior to Chief Engineer and Director of a leading Yorkshire public works and civil engineering contractor and consultancy, while at the same time establishing a worldwide reputation for his work on Carboniferous palaeontology and stratigraphy, as well as contributing much to the understanding of the Quaternary of our region.
Council wants the new award to be distinct from the Society’s existing Medals (the Phillips Medal – established with a donation from W.S. Bisat, the Sorby Medal and the Moore Medal) and therefore proposes that it be awarded to recognise excellence and outstanding achievement within the field of Applied Geology. The intention is that Applied Geology should be interpreted widely, covering not only such long-established  fields as engineering geology, mining, exploration and petroleum geology, but also increasingly important newer and emerging fields such as e.g. geoconservation and forensic geology. The detailed terms for the new award will now be drawn up by the Council and published in good time for nominations to be received and the first award to be made at the 2014 AGM.

 Some British Geological Survey Memoirs for Yorkshire to download

In a major new development for the Society, the British Geological Survey (BGS) had made available to the Society's website full facsimile copies (in PDF format, including all illustrations) of some earlier Geological Survey Memoirs, listed below. These are now available for downloading for personal, academic, educational, non-commercial research and other non-commercial use, from the Yorkshire Geological Society website http://www.yorksgeolsoc.org.uk/ only. All users must agree to the BGS terms and conditions before downloading each Memoir.
Go to Geological Survey Memoirs index page

Searchable Indexes to 138 years of the Proceedings of the Yorkshire Geological Society (1837-1995) now available on line

The Society has been publishing its Proceedings since 1837, and its many thousands of pages contain a great deal of original research and other unique material relating to the earth sciences, especially in respect of Yorshire and adjacent regions, both also nationally and internationally.  Complete reference sets of the PYGS are held by many leading regional and national libraries including the British Library, the Geological Society LIbrary, and the Society's own library, now part of the University of Leeds Library (which members of the Society can apply to use as a benefit of membership via the General Secretary of the Society).
Over the years the Society has published three cumulative indexes to the Proceedings, but it has been an aim of the Society's Council to make these indexes available on line via this website to help members and others to search and explore the rich resources available in the Proceedings
We are delighted announce that thanks to the generous help of Pinpoint Digital of Winsford, Cheshire, which has undertaken the necessary scanning of the published indexes free of charge, these are now available as searchable PDF files as follows:
Index to PYGS volumes 1 to 25 (1837-1946)
Index to PYGS volumes 26 to 37 (1947-1970)
Index to PYGS volumes 38 to 50 (1970-1995
To access each index click on the appropriate link above to open or download the file. (Each is very large - over 2Mb - so unless you have a fast broadband connection it is advisable to download the files onto your own hard disk, and then search from there.  Whether using an index on line or from a downloaded file simply open the file in  Adobe Acrobat and then use the normal Acrobat "Search" (or "Find") facility.  Any geological term, placename or author name can be used to search each index: Acrobat will then give you a list of occurences in the subject or author indexes, and each occurence is highlighted in colour within ePDF (facsimile) image of the index page. 
Very many thanks to Pinpoint Digital Document Management and Storage Systems for their sponsorship,and particularly John Hatton for his advice and practical assistance.

Yorkshire Rocks and Landscapethe 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

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).
