Abstract

The present study focuses on sediment grain size, microfossil content and heavy minerals present in the sediments collected from a trench in the southeast coast of India in order to identify the frequent extreme wave events (e.g. storm surge, cyclone, tsunami, etc.). Two different depositional events were identified at different depths with distinct sedimentological, mineralogical and microfossil characteristics. These geological features further improve the understanding of depositional sequences in this region.

Keywords: ostracoda, foraminifera, trench sample, Velanganni, southeast coast of India.
