Armalcolite is a titanium-rich mineral that falls under the magnesianferropseudobrookite mineral group with Fe 2+ Ti 2 O 5 and MgTi 2 O 5 as end members. [8] Due to having octahedral symmetry, armalcolite has solid solution (cation substitution) between multiple elements Fe 2+ , Fe 3+ , Mg, Al, and Ti; this is because of their similarities in ...
2 Si 2 O 5 (OH) 4 ·2H 2 O), halloysite-7Å (Al 2 Si 2 O 5 (OH) 4) and gibbsite (Al(OH) 3) are thought to be products of tuff weathering. Betalommosovite was described by Gerasimovskiy and Kazakova (1962) and discredited by the IMA-CNMMN (IMA1967 s.p.). It was published without approval and listed as discredited on the 'IMA/CNMNC List of ...

The first set of commonly used mineral symbols was published in 1983 and covered the common rock-forming minerals using 192 two- or three-lettered symbols. [1] These type of symbols are referred to as Kretz symbols. More extensive lists were subsequently made available in the form of publications [2] [3] or posted on journal webpages. [4]

Native element minerals are those elements that occur in nature in uncombined form with a distinct mineral structure. The elemental class includes metals and intermetallic elements, semi-metals and non-metals. This group also includes natural alloys, phosphides, silicides, nitrides and carbides.
