- ABOUT THE GEOLOGY SECTION -

The origins of the Woolhope Club reach back to the founders' interest and research in the geology of the Woolhope Dome and its Silurian stratigraphy, dating from the mid-19th century. Amongst other subjects, geology has featured in its activities ever since. However, in November 2002 a specialist Geology Section was formed so that this field of interest could be pursued more actively, both by enthusiasts within the Club and other prospective members.

Participation is therefore open to all existing (and prospective) members of the Woolhope Club, with a programme of meetings and field excursions arranged each year.
 

The Section publishes an annual Newsletter. The left-hand logo is the Club's (which incorporates a cross section through the Silurian Woolhope Dome, the anticlinal structure being revealed by the symmetry of blue-coloured beds around a grey core) and the right-hand logo is the geological map of the Woolhope Dome. Earth Matters contains news and reviews of the Section's activities, written and edited by members.
   

If you wish to join the Geology Section please contact the Honorary Treasurer & Membership Secretary, Mrs Beryl Harding, at the above address.

 

- ABOUT THE GEOLOGY OF HEREFORDSHIRE -

Dominated by the Old Red Sandstone but fringed by older rocks and covered in a mantle of Quaternary 'Ice Age' deposits, Herefordshire's bedrock geology is almost entirely sedimentary in origin.

Nevertheless the variety of geological phenomena is amazing and the landscape is beautiful, the two being inextricably interlinked. This is explored further in the Geology Section's current project, writing a book entitled The Geology of Herefordshire, to be published in 2015. Meanwhile you may wish to read the overview written by Ron Shoesmith in 1982, in CBA Research Report No.46.

Geological maps of Herefordshire still largely rely on the initial mapping conducted by the Geological Survey in the 1860s, a summary version of which appeared in Stanford's Atlas (which can be inspected by clicking here and scrolling about halfway down the page). The BGS is currently resurveying the area and their coverage can be inspected by clicking here to open a new window and dragging open the region around Hereford.

If you wish to know more, a number of papers have been published in the Transactions of the Woolhope Club, and specimens can be examined in the museums at Hereford and Ludlow.

There is also a useful page of links on the Shropshire Geological Society web page, accessible by clicking here.

 

- EARTHQUAKES IN HEREFORDSHIRE -

Minor earthquakes occasionally occur in Herefordshire, usually as a result of movements along faults some kilometres down in the basement, well beneath the rocks which are seen outcropping at the surface. Two notable earthquakes have taken place in historical times. The largest was a magnitude 5.3 event on 17 December 1896 (a substantial account of which, by Charles Davison, is in the Woolhope Club's library; the text of a summary by Davison has been made available through Project Gutenberg). The most recent was a magnitude 3.6 event on 26 October 2008, details of which have been posted by the BGS.
