Serpentine is a group name given to a family of closely related hydrated magnesium silicate minerals that form through the alteration of ultramafic rocks. Recognised for their silky...
Zeolite refers to a diverse group of hydrated aluminosilicate minerals that possess an open, three-dimensional crystal framework capable of reversible cation exchange and water adsorption. These minerals are...
Calcite is a calcium carbonate mineral with the chemical formula CaCO₃. It is among the most abundant and widely distributed minerals on Earth, forming in igneous, sedimentary, and...
Dolomite is a carbonate mineral composed of calcium magnesium carbonate (CaMg(CO₃)₂) and is the principal component of the rock known as dolostone or dolomite rock. Distinguished by its...
Siderite is an iron carbonate mineral with the chemical formula FeCO₃, belonging to the calcite group of carbonate minerals. It derives its name from the Greek word sideros,...
Barite, also spelled baryte, is a barium sulphate mineral with the chemical formula BaSO₄. It is the principal ore of barium and one of the most common sulphate...
Gypsum is a widely occurring hydrated calcium sulphate mineral with the chemical formula CaSO₄·2H₂O. It is one of the most abundant and versatile evaporite minerals on Earth, found...
Anhydrite is a calcium sulfate mineral with the chemical formula CaSO₄, closely related to gypsum but distinct in lacking water molecules in its structure. Its name is derived...
Celestite, also known as celestine, is a naturally occurring strontium sulfate mineral (SrSO₄) celebrated for its delicate sky-blue colour and transparent crystal forms. The name derives from the...
Witherite is a relatively rare carbonate mineral whose chemical formula is BaCO₃ (barium carbonate). It is one of the principal ores of barium and holds importance in mineralogy,...
