Jamaica's geology is dominated by limestone. This sedimentary rock is formed primarily from the accumulation and cementation of the skeletal remains of marine organisms, such as coral, algae, and mollusks.

Here are some specific types of limestone found in Jamaica:

* Reef Limestone: This type is formed by the growth and accumulation of coral reefs, common along Jamaica's coastlines.

* Calcareous Oolite: These are small, rounded grains of calcium carbonate that are formed in shallow, warm, agitated waters.

* Bioclastic Limestone: This type is composed of fragments of shells, corals, and other marine organisms.

While limestone is the most prevalent, Jamaica also features other sedimentary rocks in smaller amounts, including:

* Sandstone: Formed from the accumulation and cementation of sand grains.

* Conglomerate: Composed of rounded fragments of gravel and larger rocks.

* Mudstone: Formed from the accumulation and compaction of fine-grained mud.

It's important to note that these sedimentary rocks are often interlayered, creating a complex geological history for the island.
