Syndepositional cementation by fibrous calcite is limited to coral grainstones in forereef facies in the Lirio Limestone (Fig. 9-11 A). Fibrous calcite cement consists of elongate nonluminescent fibers, 240 μm in length, forming continuous isopachous layers around skeletal fragments and thin linings inside foraminifera tests.

Limestone. Rock Type: sedimentary Composition: mostly calcite Environment: There are several ways for limestone to form. Calcite dissolves easily in warm water but when the concentration reaches a certain threshold, the calcite comes out of solution and is deposited on the sea floor as a chemical precipitate.Laterite is a soil type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content.

Onyx is a name used for both a banded variety of quartz and a banded variety of calcite, so don’t be confused by the term’s double use. Both types of onyx are used as decorative stone, but differ in their uses. Calcite onyx is much softer than quartz onyx and is more easily carved, so it is used for most ‘onyx’ carvings.
