Descriptions of two thin sections from the glacial sediments exposed at Great Orton, Cumbria

This report describes the micromorphology of a prepared sample of Quaternary glaciogenic sediment and a glacial erratic exposed near Great Orton, Cumbria, on the southern side of the Solway Firth. The work forms part of the Southern Scotland Project of the Geology and Landscape Northern Britain Programme. The first part of the report provides a detailed description of a single thin section of an unconsolidated, sandy, silty clay present near the base of the section. The remainder of the report describes the mineralogy and petrology of a large granitic erratic found within the glaciogenic sequence and now located at the entrance to the Watchtree Nature Reserve at Great Orton.
