[Chemical composition] The composition is not fixed, roughly K2O>6%, H2O 8-9%, SiO2 50-55%, Al2O3 25-33%. Compared with muscovite, potassium is significantly reduced and water is significantly increased.
[Form] Monoclinic system. The crystals are in the form of small scales, and the aggregates are often in the form of clods.
[Physical properties] White, glass luster, aggregate is earthy luster. There is a sense of grease. Hardness 1-1.5. The cleavage parallel {001} is extremely complete. Sheet elasticity is weaker than muscovite. The proportion is 2.6-2.9.
[genesis and occurrence] Sphlogopite is the intermediate transition product of muscovite transformed into clay mineral by weathering, and is the main mineral component of clay and clay rock ( shale , mudstone).
[Identification characteristics] Large crystal particles can be identified according to scaly morphology, cleavage, weak elasticity, grease gloss, and the like.
