Summary: Planktonic foraminifera of Oligocène age were recovered at only thirteen of the forty-six Indian Ocean Deep Sea Drilling Project sites, all but one of which were situated on topographically high structures. Calcium carbonate dissolution is intense in all assemblages, which are often reduced to a few solution-resistant and typically long-ranging species. This preservation pattern suggests a shallow lysocline in the Indian Ocean throughout most of this interval. Abstract Copyright (1977), by the American Geophysical Union.
