Calcite crystal and chemical formula

* it form in rhombohedral class chemical formula:caco/3

Magnasite formation and process, dunite

 

* Host rock of magnasite is dunite

* Who  dunite is  formed, while magma cooling and consolidation 

While under goes crystallization

*Which type of crystallization,that is equilibrium crystallization

What do you mean by equilibrium crystallization

* While magama cooking starting and ending composition same is called equilibrium crystallization, it form olivine and dunite is formed

* Hydrothermal cavity filling deposit: liquid material (carbonasies) intruder in the fraction of the rock.

* It reacts with host rock dunite (dunite is a mono mineralic rock) mg/3si0/4  it form magnasite 

* It is one of the best example for matasomatism process

* salem is the world second hydrothermal cavity filling deposit (chock hills of salem
