  2016612 · MARS MINERALS What do we have? Feldspar is plentiful on celestial bodies and contains a lot of aluminum. One sample from the Moon returned by Apollo was pure anorthite. The Thermal Emission Spectrometer on Mars Global Surveyor detected a lot of feldspar including microcline, andesine, and a lot of bytownite.

  Experimental study of anorthite dissolution and the relative …

  The variation of alkali feldspar dissolution rates with aqueous Al activity stems from the fact that the formation of this precursor requires the removal of Al. In contrast, because it has a Si/Al ratio of 1, the removal of Al from the anorthite …

  2022412 · The feldspar with a composition between orthoclase and albite is known as alkali feldspar owing to the presence of alkali ions such as K + and Na ++, and the version between anorthite and albite as plagioclase feldspar. Feldspar is especially abundant in igneous rocks (e.g. granite).

  Anorthite (Feldspar) - National Gem Lab

  Anorthite could be the member that is rarest of Plagioclase Feldspars for the Feldspar number of minerals that includes Albite, Amazonite, Andesine, Anorthite, Bytownite, Hyalophane, Labradorite, Moonstone, Oligoclase, Orthoclase, Sanidine and Sunstone. The Plagioclase Feldspars form a string between Albite and Anorthite. Albite is the sodium …

  Plagioclase | Encyclopedia MDPI

  20221125 · Plagioclase is the primary aluminium-bearing mineral in mafic rocks formed at low pressure. It is normally the first and most abundant feldspar to crystallize from a cooling primitive magma. Anorthite has a much higher melting point than albite, and, as a result, calcium-rich plagioclase is the first to crystallize.
