Title: Ostracoda of Coastal Group of Formations of Jamaica: ABSTRACT

Author(s): W. A. Van Den Bold

Article Type: Meeting abstract


Traditionally the group of formations that crops out along the northeast, east, and southeast coasts of Jamaica, has been divided into an upper and lower part. The upper, of Pleistocene age, includes the Manchioneal Formation with the Navy Island Member, and the beds in the upper part of the Bowden section. The lower part, at least partly of Pliocene age, includes the Bowden Formation, the San San clay, the Buff Bay Formation and overlying beds in the Buff Bay section, and the August Town Formation.

Correlation of 8 different sections by means of ostracods shows some discrepancies with Blow's correlation, based on planktonic forams. Distribution of ostracods in the August Town Formation suggests that its age is older than that of the Bowden shell bed. The overlying Harbour View beds are brackish-water deposits. A new species of Cyprideis, with reversal of overlap and hinge, has been found.
