A note on Paleocene fossils from the white limestone in eastern Jamaica
The journal of the Geological Society of Jamaica
Date of Publication
Larger and planktonic foraminifers at several limestone localities in the John Crow Mountains area, eastern Jamaica, appearing on published geological maps as White Limestone Supergroup (Group/Formation of authors), are indicative of late Paleocene, to possibly early Eocene ages. There appears to be no lithostratigraphic reason to separate these rocks at or near the base of the White Limestone in this region, from the White Limestone in other parts of Jamaica. However, west of the John Crow Mountains, the base of the White Limestone has not been shown to extend lower than the upper part of the middle Eocene. These data support earlier suggestions that the change upwards from siliciclastic to carbonate sedimentation, may have occurred some 15 million years earlier in eastern Jamaica than over the central and western parts of the island, suggesting a significant difference in the geological history of the two regions.....
