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 ...

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.
This list includes those recognised minerals beginning with the letter N.The International Mineralogical Association is the international group that recognises new minerals and new mineral names; however, minerals discovered before 1959 did not go through the official naming procedure, although some minerals published previously have been either confirmed or discredited since that date.
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 ...

Magnesium oxide, more commonly called magnesia, is a mineral that when used as part of a cement mixture and cast into thin cement panels under proper curing procedures and practices can be used in residential and commercial building construction. Some versions are suitable for general building uses and for applications that require fire ...
Mineral associations may vary (1) in different mineralized structures, either syngenetic (namely, passive precipitation in chimneys, mounds and stratiform deposits) or epigenetic (structures that correspond to feeder channels, and replacements of host rocks or pre-existing massive sulfide bodies), or structural zonation, (2) from proximal to ...
