Abstract

Abstract The Early Miocene sequences of North Passage Island iu the Andaman Sea have been studied for their siliceous and calcareous microfossil assemblages. 95 species of radiolaria and 27 species of planktonic foraminifera belonging to these two major groups of microfossils have been documented. An integrated radiolarian ancl planktonic foraminifera1 biostratigraphy is presented.
