Tanzanite is a variety of Zoisite. It is valued as a gem stone and has the chemical formula Ca2Al3Si3O12(OH).
Talc is a metamorphic mineral from the silicate family. Its chemical formula is hydrated magnesium silicate H2Mg3(SiO3)4. Talc is commonly used as talcum powder to reduce friction, promote dry skin, and prevent rashes.
selenite Selenite is a very common chemical sedimentary mineral. Its chemical formula is Calcium Sulfate dihydrate CaSO42H20, It is a form of gypsum. It is a very soft mineral
Calcite Calcite is a very common sedimentary mineral. It has the chemical formula CaCO3 calcium carbonate. Calcite dissolves in water and so is carried along with water into cracks, fissures, and caves. It can over time build up layer upon layer to form stalactites and stalagmites in caves
