Abstract

Planktic foraminiferal studies from the southern Bay of Bengal (SBBT) indicate the presence of corroded specimens of Globorotalia menardii in the deep trap at a depth of 3011 m during February-March 1992. Strangely, all the other spinose and less resistant spinose foraminiferal species are found devoid of any signs of dissolution in association with the highly corroded specimens of Gr.menardii. In view of the above and also to the fact that this trap depth is well above the lysocline, it is postulated that these corroded specimens of Gr.menardii tests could have been supplied by lateral advection and mixed up with the settling particles at SBBT, thus this assemblage is a resultant of two different sources, during this particular period.
