Radiocarbon and thermoluminescence dating of the Old Alluvium from a coastal site in Perak, Malaysia

Journal Article


Abstract


  • Exposures of the 'Old Alluvium' in Pantai Mine and Sinar Manjung Mine in Perak, Peninsular Malaysia, reveal woody peat layers interbedded with angular sands and gravels. Eight samples from peat within the Pantai Mine were dated using accelerator mass spectrometry (AMS) radiocarbon dating, together with a near-surface shell sample. Five samples of quartz sand from the Pantai Mine and three samples of similar sand from Sinar Manjung Mine were dated by thermoluminescence (TL) dating. While for several samples both dating techniques were at the limits of their detection, results from the upper strata of the northwestern face of the Pantai Mine indicate agreement between the two independent dating techniques. The age of the Old Alluvium, known as the Simpang Formation in Perak, is confirmed as Late Pleistocene at this site. The measured ages range from 28,000 years B.P. to 67,000 years B.P., but the lower units are older than this and appear at this site to be beyond the range of both dating techniques. © 1993.
