Montmorillonite
Montmorillonite is a phyllosilicate mineral with the chemical formula (Na,Ca)0.33(Al,Mg)2(Si4O10)(OH)2 * nH2O, indicating a structure composed of variable sodium and calcium cations, aluminum and magnesium in the tetrahedral and octahedral layers, and water molecules in the interlayer. It crystallizes in the monoclinic system and is characterized by a very low Mohs hardness of 1.3, a density of 1.8 g/cm³, and a dull to pearly luster. It typically appears in a range of colors, including white, gray, green, or yellow. Montmorillonite is classified as a 2:1 clay mineral in the smectite group and is commonly found in fine-grained sedimentary and hydrothermal environments.
Overview
Montmorillonite is a phyllosilicate mineral with the chemical formula (Na,Ca)0.33(Al,Mg)2(Si4O10)(OH)2 * nH2O, indicating a structure composed of variable sodium and calcium cations, aluminum and magnesium in the tetrahedral and octahedral layers, and water molecules in the interlayer. It crystallizes in the monoclinic system and is characterized by a very low Mohs hardness of 1.3, a density of 1.8 g/cm³, and a dull to pearly luster. It typically appears in a range of colors, including white, gray, green, or yellow. Montmorillonite is classified as a 2:1 clay mineral in the smectite group and is commonly found in fine-grained sedimentary and hydrothermal environments.
Etymology
Montmorillonite is named after Montmorillon, a town in France where the mineral was first identified. The name reflects its type locality, though no specific discovery year is provided in the facts.
Geological genesis
Montmorillonite typically forms through the weathering of volcanic ash or the alteration of other silicate minerals in low-temperature hydrothermal or sedimentary environments. As a member of the smectite group, it is commonly associated with diagenetic and low-grade metamorphic processes.
Occurrence
Montmorillonite is commonly found in sedimentary rocks, particularly in shales and clays, and in areas of volcanic ash alteration. Specific localities are not provided in the facts.
