1 Definition

1.1 Definition

Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight

A ganister is a hard, fine-grained quartzose sandstone or orthoquartzite which is basically used in the manufacture of silica brick typically used to line furnaces and is a type of sedimentary rocks.

1.3 Etymology

From French, from the name of Dolomieu (1750–1801), the French geologist who discovered the rock

From gan′is-ter i.e a hard, close-grained siliceous stone, often forming the stratum which underlies a coal-seam

5 Formation

5.1 Formation

Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.
