Lithology and environment
| Primary lithology: | planar lamination,fine,pebbly silty "siliciclastic" |
| Includes fossils? | Y |
| Lithology description: The base of the member comtains boulder-rich diamicton, interpreted here as till. Overlying this is a sequence of finely laminated silty clay with scattered stones. The top of this member is usually truncated and the fine sediments are overlain by the sandy member B with an erosional hiatus. | |
| Environment: | marine indet. |
| Glacial or sequence phase: | regressive |
| Geology comments: Scattered mollusc shells in the clay-silt sediment show that it is marine and Member A is interpreted as glacigenic and glaciomarine from the end of a major glaciation of the area. The marine sediments were probably sedimentated during the isostatically conditioned regression that followed te glaciation. | |
