The Middle Pleistocene of north Birmingham
The Older Drift of north Birmingham infills a system of pre-glacial valleys. Its stratigraphy has been worked out, chiefly from borehole records, showing it to comprise the deposits of two separate glaciations—the Lower and Upper Glacial Series, and an intervening Interglacial Series. It records the...

The Older Drift of north Birmingham infills a system of pre-glacial valleys. Its stratigraphy has been worked out, chiefly from borehole records, showing it to comprise the deposits of two separate glaciations—the Lower and Upper Glacial Series, and an intervening Interglacial Series. It records the deposition during the Lower Glacial Series of fluvioglacial sediments followed by those of a glacial lake during the late-glacial period. A small remnant of the latter persisted into the Interglacial as a lake at Nechells and was gradually infilled with lake muds. After a temporary period of low water the level subsequently fell again, largely draining the lake which became covered with fen-wood and marsh receiving some fluviatile sediment. Other thin interglacial beds exist at Cardigan Street and possibly Washwood Heath. Elsewhere the period is represented by an unconformity. The Upper Glacial Series records the triple advance into the area of valley glaciers, accompanied by the formation of glacial lakes. In the intervening periods of retreat the valleys were receiving fluvioglacial sediment, and in one period were occupied by a second large glacial lake. A fourth advance of an ice sheet covered the area and completed the infilling of the valleys.
