A 30,000-Year Pollen and Radiocarbon Record from Highland Sumatra as Evidence for Climatic Change

Abstract

We examine the pollen analytical and 14C sequences from two Sumatra highland sites, Pea Bullok (2 degrees 15'N, 99 degrees 02'E) and Danau di-Atas (1 degree 04'S, 100 degrees 46'E). The pollen diagrams do not correlate particularly well, possibly because two of the samples from Danau di-Atas analyzed by radioactive decay counting earlier should be infinite. Other complications are differences in the type of site, local topography, pollen sums used and difficulty in distinguishing between pollen taxa from local and regional vegetation. The older material from Pea Bullok was AMS dated.
