Genesis of magnesite

Date of release:2018-07-13 Author: Click:

There are two main causes of magnesite formation. One is exogenesis, which occurs in sedimentary rocks. Most of these layered clastic sedimentary rocks contain organic components from organisms. In other words, magnesite is formed by biological action under the condition of low oxygen; Liaoning two calcium fused magnesia.

Secondly, it is formed in hydrothermal veins of middle to low temperatures: magnesite is commonly found in metamorphic sedimentary rocks, gangue minerals formed after hydrothermal accumulation; in addition, magnesite may occur in pegmatite.

Genesis of magnesite

The common associated minerals are quartz, pyrite, limonite, goethite, chalcopyrite, sphalerite, cryolite, galena, barite, calcite, dolomite, fluorspar. ITE) and so on.

Because of their similar crystalline structure, these minerals have many similar physical properties, such as the triangular system, (trigonal) - crystalline type is mostly rhombohedral or scalenohedron, there are three groups of well-developed rhombohedral cleavage, and the transparent rhombohedral crystals have double refraction. In fact, cations in the mineral composition can completely replace each other to form a series of solid solutions, so the resolution between minerals may become more difficult.
