Saturday 30th August 2008 — Huddersfield White Rock
|
Leader: Tony Benfield, BGS (retired), former LGA President.
Purpose: To demonstrate some of the constituent lithofacies of the sandstone member of a late Namurian (Marsdenian Sub-stage) cyclothem and to link them to their deltaic and fluvial depositional environments.

Fri 12th - Sun 14th Sept 2008 — Residential Weekend: Glamorgan
|
|
|
Saturday 4th October 2008 — Howardian Hills
|
Leader: Jon Ford & Simon Price, BGS.
Purpose: An overview of the Jurassic succession of the Howardian Hills – the southern limit of the Cleveland Basin. We will visit several localities that demonstrate the local succession and show how regional tectonic events during the evolution of the Basin have affected sedimentation. We hope to visit one active quarry to demonstrate economic opportunities resulting from the atypical succession, and will show how recent work by the BGS is improving our understanding of local geohazards.
Geology: Jurassic, Cretaceous, Quaternary.
