The micromorphology of the Quaternary deposits associated with the Carstairs Eskers, Lanarkshire, Scotland

This report describes the micromorphology of prepared samples of Quaternary sediments
exposed in the Carstairs area of Central Scotland. The work forms part of the Midland Valley
Terrane project of the Integrated Geological Survey (north) Programme.
The first part of the report provides the background information on the Quaternary geology of
the Carstairs area. This is followed by a section describing the detailed micromorphology of five
large format thin sections of the matrix of an unconsolidated very coarse diamicton and the
underlying sands, silts and clay layers. The results are used to develop a model for the
emplacement of a very coarse-grained mass flow deposit present within the Carstairs Quaternary
sequence.
