Yellow Limestone Group

Introduction

The rocks of the Yellow Limestone Group represent the first to be deposited across the eroded mountains produced by the collision of the Jamaica arc with the Yucatan Block. These rocks show a progressive onlap from north to south across Jamaica and eventually the establishment of open marine, platform carbonate deposits.

The rocks of the Yellow Limestone Group range from clastics (conglomerates, sandstones, siltstones and shales), through impure limestones and marlstones to pure limestones. Often these different rocks are interbedded so that a relatively pure limestone (e.g., Stettin Formation) may be followed by a clastic unit (e.g., Litchfield Formation).
