摘要

Archaeological excavations at the Palaeolithic site of Attirampakkam, Tiruvallur District, Tamil Nadu, yielded artefacts dating to the Lower and Middle Palaeolithic cultural phases assigned to the Middle to Late Pleistocene. This communication reports preliminary results of clay mineral analysis, which suggests the influence of both provenance and climate during the Pleistocene. The higher Sr-87/Sr-86 values suggest chemical weathering of silicate minerals present in the host sediments as the predominant source for Ca in the calcretes.
