Formula: CaMg(CO 3) 2 Hexagonal Description: Dolomite is an abundant mineral in Wisconsin. It is a major rock-forming mineral in the sedimentary dolostones within the Prairie du Chien group (Oneota and Shakopee formations), Sinnepee Group (Platteville, Decorah and Galena Formations) and the Niagaran rocks.
Dec 03, 2013· Dolomite is also a sedimentary rock type. When dolomite is formed, several steps of dissolution and re-precipitation is passed where the structure of the mineral is modified into more stable forms and crystallizes in a trigonal-rhombohedral manner.
The oldest rocks that lie within the area of dolomite deposits in clude sheared conglomeratic quartzite and slates or phyllites which are clearly unconformable beneath the dolomite, limestone, and other rocks making up the carbonate succession. All these rocks have been recently described by Waters and Krauskopf.

rocks (many types) Schists and Gneisses In general, the iron and magnesium rich rocks are altered to schists and amphibolites, whereas the silica and aluminum rich rocks form gneisses, but almost any variation is possible because of variations in intensity of metamorphism and also because of the opportunity for the addition or removal of elements.

Antiporda ...
The principal mineral of limestone is calcite (CaCO3), a form of calcium carbonate. Dolostone is quite similar to limestone, but is composed mostly of the mineral dolomite (CaMg(CO3)2). Both are sedimentary rocks that occur as thin to massive beds of fine- to coarse-grained rock.
