Stone age archaeology and environment on the Southern Accra plains, Ghana

Excavations at Asokrochona and Tema West I have uncovered an industry that has tentatively been assigned to the Sangoan. The sites were in use during a period when the climate and environment were like today's. With a change to more arid conditions between 25000 and 13500 B.P. tool types and settlement pattern changed considerably. Between 13500 and 4000 B.P. the Plains experienced a relatively humid period. Sites with a small scale flake industry and pottery are common towards the end of the period. At Kpone such artefacts are found in a shell‐midden. With the onset of a dry period between 4000 and 3500 B.P. traces of human occupation disappear. Succeeding sites belong to the Iron Age.
