Dolomite,malachite and gypsum are distinct minerals that vary significantly across their crystal structures,chemical makeup and environmental origins.
Dolomite:
Crystal system- Trigonal
Mineral class- Carbonate
Hardness- 3.5-4 on the MOHs scale
Rock formation- formed primarily via dolomitization (where magnesium rich groundwater alters existing limestone) it is a major component of the sedimentary rock dolostone.
Malachite:
Crystal system- Monoclinic
Mineral class- Carbonate Hardness
Hardness- 3.5-4 on the MOHs scale
Rock formation- Formed as a secondary mineral via the supergene weathering and oxidation of primary copper sulfide ore deposits,typically occurring near limestones.
Gypsum:
Crystal system- Monoclinic
Mineral class- Sulfate
Hardness- 2 on the MOHs scale
Rock formation- Formed primarily as an evaporite mineral in sedimentary marine lagoons and hypersaline lakes as water evaporates. It forms massive rock gypsum beds.
