Excursion title:

North Esk Inlier, Pentland Hills: North Esk to the Lyne Water – a road less travelled

Date & time:

Saturday 2nd September 2017, 9 am

Finish time:

5 pm at end of public road, Baddinsgill NT126548

Leader:

Ken Shaw, EGS

Excursion aims and description:

The North Esk Inlier is a sequence of sedimentary rocks formed at the edge of the Iapetus Ocean in the Silurian period, ranging from mudstones to conglomerates. We will examine and discuss the depositional environments of these rocks, and how they relate to the fossils within them. There will be opportunity to collect fossils from loose material, accurately described in the field guide as “splendidly preserved as undistorted moulds … succeeding each other through time and directly linked with changing environments”. Other aspects of the local geology and geomorphology will also be highlighted and discussed.

The North Esk and Lyne Water are both Sites of Special Scientific Interest, so we will not allow any hammering of bedrock exposures. There is ample loose material that can be split by hand, so no hammers please.
