It typically shares the same crystal structure as rutile. Well formed crystals are rare. It usually occurs in massive,granular or columnar habits,or as distinctive dendritic patterns.\u003c\/p\u003e\n\u003cp\u003eMineral class-\u003cbr\u003ePyrolusite belongs to the oxide mineral class. Its chemical composition is magnesium dioxide.\u003c\/p\u003e\n\u003cp\u003eRock formation -\u003cbr\u003eThe mineral forms primarily through sedimentary processes and secondary weathering. It develops in highly oxidation environments.\u003cbr\u003eOxidation zones-\u003cbr\u003eFormed when primary manganese bearing minerals undergo severe weathering and oxidation.\u003c\/p\u003e\n\u003cp\u003eSedimentary deposits-\u003cbr\u003ePrecipitated directly from water in shallow marine environments,bogs or lakes ,often forming nodules or beds.\u003c\/p\u003e\n\u003cp\u003eHydrothermal veins-\u003cbr\u003eDeposited by low temperature hydrothermal fluids passing through fractures.\u003c\/p\u003e\n\u003cp\u003eHardness-\u003cbr\u003eThe MOHs hardness of pyrolusite is 6-6.5 for distinct crystals. However because it commonly occurs in aggregate,earthy or fibrous masses, it frequently exhibits an apparent hardness as low as 1-2 .which readily soils the fingers with a nock
