Scenery north of Pingdi, Guizhou Province, SW China showing Middle Permian limestones overlain by several 100 metres of volcaniclastic deposits and flood basalts of the lower Emeishan lava pile. |
Thin section photo showing a fragment of scoriaceous basalt from one of the large explosive eruptions of the Middle Permian Emeishan volcanic province, Lugu Lake, Sichuan, China. This is a typical example of the violent style of eruptions that mark the onset of volcanism. |
Contact between the base of the Emeishan volcanics (around the top of the hammer shaft) and the underlying Middle Permian limestones of the Maokou Formation. Numerous fossil species disappear in the uppermost metres of these limestones showing the very close correspondence between mass extinction and volcanism. Xiong Jia Chang, Guizhou Province. |

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.

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.

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 Societys 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).
