Abstract
Intercalated volcanic ash layers in two deep-sea sediment cores from the Ce ntral Indian Basin (CIB) are examined for the possibility of an in situ sou rce of suboceanic volcanism. An in situ source has been predicated based on the bottom morphological structures and activation of seamounts during the geological past. The tentative correlation between depositional ages of th e ash layer horizons and the period of global climatic cooling events reinf orces the hypothesis that the suboceanic volcanic episode might have been i nitiated during the onset of glaciation.
