Geology of Dolomites The Geological History and Evolution

Even other areas of the earth can be classified as Dolomite, but only in these alpine areas the geology of Dolomites has bin so big that makes it so unique. From what once was a warm and tropical see – with a position more South of what it is today – full of life and furrowed from warm sea flows, the mountains that we know today where formed.

MIDDLE PLEISTOCENE KARST EVOLUTION IN THE STATE .

The Rus Formation is composed of soft limestone, dolomitic limestone, chalky limestone, gypsum, anhydrite, and shale. The thickness ranges between 42-112 m. Most depres-sions are related to dissolution of the gypsum and anhydrite within this formation, resulting in the development of numer-ous surface-collapse depressions (Embabi & Ali 1990).

Limestone - an overview | ScienceDirect Topics

Dolomite (also called magnesian limestone) is named after the mineral dolomite CaMg(CO 3) 2 that it contains. It is formed from limestone by chemical reactions during diagenesis. Dolomitic rocks are classified according to their percentage content of the dolomite mineral as follows: • 0–10% dolomite = limestone. • 10–50% dolomite ...

Carbonate Sedimentary Rock Classification

Limestone [CaCO 3] is also chemically related to dolomite [CaMg(CO 3) 2]. Because all these rocks have CO 3 - - in common they are called the carbonates. The composition of most carbonates is derived from a combination of biological and chemical components.

Stromatolite - Wikipedia

A very rare type of non-lake dwelling stromatolite lives in the Nettle Cave at Jenolan Caves, NSW, Australia. The cyanobacteria live on the surface of the limestone, and are sustained by the calcium rich dripping water, which allows them to grow toward the two open ends of the cave which provide light.
