Dolomite also known as quotdolostonequot and quotdolomite rockquot is a sedimentary rock composed primarily of the mineral dolomite CaMgCO32. Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater.
Dolostone is quite similar to limestone but is composed mostly of the mineral dolomite CaMgCO32. Both are sedimentary rocks that occur as thin to massive beds of fine- to coarse-grained rock. Their color is typically some shade of gray but may be white tan

Abstract Crystalline limestone of the Sakonishi area in the Kamioka ZnPb mine central Japan is depleted in 18 O and 13 C toward the center of mineralization due to interaction with hydrothermal fluids with a dominant meteoric water component. The relationship between isotopic composition and mineral assemblage texture the chemical composition of the minerals and the bulk chemical .
Dolomite occurrence. Dolomite occurs in metamorphic rocks chiefly in contact or regionally metamorphosed with Magnesian or dolomitic limestone where it may recrystallize to form a dolomitic marble. At a higher extent of metamorphism the Dolomite may break down in two stages. Dolomite is different from limestone and may contain minimum 45 of .

In the central region the upper dolomite is absent so the combination of both limestone units with the lower dolomitized unit results in a quotlimestone facies.11 To the east only the thinner basal limestone and thicker lower dolomitized unit are present so the net effect is a quotdolomite facies.quot

The dolomite is believed to be a secondary replacement of original limestone while the sediment was undergoing lithification. Dolomite also forms as later drusy crystals lining vugs in dolostones. Dolomite may form as a hydrothermal replacement mineral and as such is especially abundant as a gangue mineral in the ore deposits of the Upper
Mankato-Kasota Limestone This sedimentary rock is part of the Oneota Dolostone Formation of southern Minnesota. It is quarried near the town of Mankato Minnesota. The age of this rock is 450-500 m.y. which places it in the lower Ordovician Period. The rock is a very fine-grained yellowish-tan dolostone consisting almost entirely of dolomite.
