Preliminary Programme

Venue: Grinkle Park Hotel, Easington, Cleveland, UK.
Course Leaders: Ian Davison, Earthmoves Ltd.
and Dave Waltham, Royal Holloway, University of London.

This two day combined field/lecture course will cover all aspects of Salt Tectonics and its effects on sedimentation. The course provides a unique opportunity to combine a lecture course with a visit to the deepest mine in the UK. The mine extends out 5 km below the North Sea coastline and up to 1.3 km below sea level, where you can walk around in salt rollers on the shoulder of the North Sea Central Graben! Coastal cliff exposures of salt welds and Zechstein collapse breccias will be examined at Seaham (optional extra field excursion held on Sunday before the main course starts on Monday).

OPTIONAL EXTRA. Salt welds and dissolution seams Seaham Middlesborough. ID. Note this extra field session is really an add on for people that are prepared to travel up to the area a day early for a 3 pm start, and is not considered an essential part of the course.
