John Crow Mountain Belt

Introduction

The John Crow Mountain Belt is situated in eastern Jamaica and comprises the rocks of the John Crow Mountains and Rio Grande valley. These rocks have a different stratigraphy to other parts of Jamaica. Inparticular, they have Paleocene deep-water conglomerates, sandstones and shales (possibly a K-Pe boundary succession), deep-water Paleocene bedded Marlstones-limestones (similar to the Font Hill Formation), and a massage into pure limestones (similar to the White Limestone) within the Paleocene.

The following units are present:-
White Limestone Group. Late Paleocene-Miocene. Shallow-water and deep-water limestones.
Nonsuch Formation. Mid Paleocene. Deep-water Paleocene impure bedded Marlstones-limestones (similar to the Font Hill Formation).
Mooretown Formation. Early Paleocene (?Latest Maastrcihtian). Turbiditic sandstone-shale sequence.
Bowden Pen Formation. Late Maastrichtian? Pebble conglomerates (syn rift sequence).
