Description :
The Youngest Toba Ash (Ca. 74,000 yr B.P.) occurs extensively in the Indian subcontinent. The reworked ash samples are closely similar in their bulk chemical composition, REE signature, and bubble-wall shard morphology to those from the Toba caldera and deep-sea cores from the Bay of Bengal and Indian Ocean. The Toba ash thus can be used as an event marker for regional and global Quaternary correlation.
