This is a field trip of two halves. In the morning we examine the SSI Carboniferous cyclothem sequence along the shore by Dunbar from White Sands to Barn’s Ness. The afternoon will be spent in the nearby active quarry in the same strata, where we will be the guests of Tarmac Group. An opportunity to develop a 3D perspective on this famous site and contemplate global and astronomical forces that lead to cyclicity in sedimentary sequences.

In the afternoon we will be the guests of Tarmac Group in their active quarry and will comply with their safety instructions. It is essential that participants stay with the group in the quarry.

Hard hats or Hi-viz clothing needed:

Hard hats, stout walking boots, hi-viz vests, and safety glasses are all essential PPE for the quarry visit in the afternoon.
