June 4 @ 8:00 am - June 11 @ 5:00 pm
Leaders: Allen Fraser and Robina Barton
Our first three days will be spent on the islands of Unst and Fetlar where we will examine aspects of the Shetland Ophiolite nappes. These will include depleted mantle and magma chamber rocks, inter-nappe sheared conglomerates and a later granite intrusion. We will also visit abandoned chromite quarries from the 19th. and 20th. centuries and a restored horse-driven ore crushing circle.
