The Ladies Skerrs dome, Meadow Haven, Berwick – Alison Tymon

This visit to coastal exposures around the town of Berwick-upon-Tweed will examine good coastal exposures of cyclothems, deposited in river deltas, swamps and shallow sea close to the equator. The strata include coal, fireclay, limestone and sandstone, some containing fossils. We will also examine structural evidence for the Berwick Monocline and associated faults, formed during the Variscan Orogeny. Note: this excursion is repeated from 2017, as part of a weekend visit by Yorkshire Geological Society; EGS members are welcome to attend, but transport from Edinburgh is not provided.
