HULL GEOLOGICAL SOCIETY’S MEMBERS EVENING, 9th. February 1984.

by Mike Horne

The Members’ Evening which was held in the Department of Geology, Hull University was well attended. Displays of specimens and four slide shows were given.

Mike Horne showed some slides of the sea—shore exposures of Upper Devonian and Lower Carboniferous rocks at Portishead near Bristol.

Mr. Richard Davies showed a selection of slides of a variety of geological features which he had taken in Europe, including the Moine Thrust, pillow lavas, turbidites, sole markings, folding, unconformities, bioturbation and ripple marks.

Mr. Lyn Emery showed some slides of the original cave paintings at Lascaux, France, and talked about the animals depicted and the painting techniques used. He also described the replica caves and zoo which he had visited at Lascaux.

Mr. Ken Fenton, though unable to attend, had sent some slides taken at the Society’s visit to Hessle Station to record the exposure of the buried cliff there before it was removed by contractors to make way for a new road. These slides showed the chalk cliff, the beach deposits, land wash, blown sand and overlying boulder clay. The cliff at Hessle was compared with that at Sewerby and a lively discussion about the buried cliff in Yorkshire ensued.

Mr Felix Whitham brought along marvellous displays of Cretaceous echinoids arranged in stratigraphical order, some Jurassic ammonites and Cretaceous brachiopods, most of which he had found locally. He also had a specimen of Inoceramus collected from the chalk near the Hessle buried cliff.

The Geology Department kindly opened up some of the drawers of its reserve collection to allow members to examine graptolites and some Jurassic ammonites. Also on view was a fine collection of Silurian trilobites, corals, stromatolites and brachiopods.

The Society is grateful for the Geology Departments hospitality in acting as hosts and for contributing to the success of the evening.
