The classification of minerals is a process of determining to which of several groups minerals belong based on their chemical characteristics. Since the 1950s, this classification has been carried out by the International Mineralogical Association, which classifies minerals into the following broad classes: Classification of non-silicate minerals
Dana's classification [1] [2] is a mineral classification developed by James Dwight Dana. It is based on the chemical composition and structure of minerals. It is mainly used in English-speaking countries, especially in the United States. The mineral classification used by the International Mineralogical Association is the Nickel-Strunz ...
Classification of minerals — includes:; Class 01 - Elements: Metals and Alloys, Carbides, Silicides, Nitrides, Phosphides; Class 02 - Sulfides, Sulfosalts ...
They found that Earth, with over 4800 known minerals and 72 elements, has a power law relationship. The Moon, with only 63 minerals and 24 elements (based on a much smaller sample) has essentially the same relationship. This implies that, given the chemical composition of the planet, one could predict the more common minerals.
Mineral classification schemes and their definitions are evolving to match recent advances in mineral science. Recent changes have included the addition of an organic class, in both the new Dana and the Strunz classification schemes. [152] [153] The organic class includes a very rare group of minerals with hydrocarbons. The IMA Commission on ...
Normative mineralogy is an estimate of the mineralogy of the rock. It usually differs from the visually observable mineralogy, at least as much as the types of mineral species, especially amongst the ferromagnesian minerals and feldspars, where it is possible to have many solid solution series of minerals, or minerals with similar Fe and Mg ratios substituting, especially with water (e.g ...
Cover of the first edition of the Strunz Mineral Classification. Nickel–Strunz classification is a scheme for categorizing minerals based upon their chemical composition, introduced by German mineralogist Karl Hugo Strunz (24 February 1910 – 19 April 2006) in his Mineralogische Tabellen (1941). [1]
Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish the various species. Within a mineral species there may be variation in physical properties or minor amounts of impurities that are recognized by mineralogists or wider society as a mineral variety.
