What Is Dolomite? Identification In The Field And Metamorphism!

Also known as “dolostone” or “dolomite rock,” the mineral dolomite has a chemical composition of CaMg(CO3)2. Dolomite is found in global sedimentary basins. The formation is generally done by the post-depositional alteration of limestone and lime mud by magnesium-rich groundwater. Dolomite mining survey companies still need it.

Facts About Dolomite: Identification In The Field

• Limestone and dolomite are very similar in nature. They share a similar range of colors from white to grey and white to light brown. Other colours also exist like red, black, and green dolomite. 
• They have approximately similar hardness and are both soluble in dilute hydrochloric acid. Industries crush and cut both of them to use as a construction material. Moreover, they have the ability to neutralize acids as well. 
• Dolomite is a common rock in the records. However, as a mineral, it has rare occurrences in sedimentary environments. Due to this reason, companies believe that most dolomites occur when limestones and lime muds have modifications by the post-deposition process. 
• Dolomite emerges in similar sedimentary environments as limestone such as warm, shallow, and marine environments. Here, the calcium carbonate mud accumulates in the form of shell debris, coral fragments, carbonate precipitates as well as fecal material. 
• Formation of dolomite is thought when the calcite (CaCO3) present in carbonate mud or limestone is modified by magnesium-rich groundwater. Thus, the available magnesium enhances the conversion of calcite into dolomite (CaMg(CO3)2).

Metamorphism Of Dolomite:

1. Dolomite often behaves like limestone while subjecting to high pressure and heat. It starts to recrystallize with the rise in temperature. As this occurrence takes place, the size of the mineral in the rock increases, and the rock forms a distinctly crystalline structure. 
2. If you observe the picture of granular dolomite, you will be able to notice that the rock consists of easily recognizable dolomite crystals. 
3. Moreover, the coarse crystalline texture is an indication of recrystallization, most often happening due to metamorphism. Lastly, the transformation of dolomite into a metamorphic rock is known as dolomitic marble.
