Abstract

Organic constituents present in the Muthurajawela peat deposit of Sri Lanka, have been investigated. Here, we report the variations with depth of sitosterol and sitostane (stigmastane), which were found to be major constituents of extracts and, hence, were selected to study the process of diagenesis. These two compounds were present in anomalous concentrations in the middle horizon of the depth profile. Considering the stratigraphy and sterol concentrations, it can be concluded that the middle horizon resulted from a sudden terrestrial input, which could have been due to a Pleistocene or Quaternary environmental change.
