The magnesite deposits are in pre-Cambrian crystalline limestone. They were formed by replacement of the calcium in limestone or dolomitized limestone by magnesium, which probably was carried by hypogene solutions. The resulting bodies are massive and lenticular, and consist of fine-grained to coarse-grained crystalline magnesite.

The majority of Marble deposits will be turned into small crushed stones, or "dimension" stones.

Feb 03, 2017· Organic Matters of Limestones. In mining-regions where the ores occur in limestone, it is observed that in most instances the largest and most productive mines are in belts or zones of crystalline limestones which are either exceptionally pure lime-carbonates or, more frequently, dolomites with only a small amount of insoluble matter.

Limestone my be crystalline, clastic, granular, or dense, depending on the method of formation. Crystals of calcite, quartz, dolomite or barite may line small cavities in the rock.
