Feldspars (KAlSi 3 O 8 - NaAlSi 3 O 8 - CaAl 2 Si 2 O 8 ) are a group of rock-forming tectosilicate minerals which make up as much as 60% of the Earth's crust. Feldspars crystallize fro...

Plagioclase is well displayed in a gravestone. ... Plagioclase tends to be more transparent than alkali feldspar; it also very commonly shows striations on its cleavage faces that are caused by multiple crystal twinning within grains. These appear as the lines in this polished specimen.

Plagioclase is not amongst the most valuable ore types around, but it has the largest amount of Pyerite of any ore and is thus always in constant demand. It also yields some Tritanium and Mexallon. It has a volume of 0.353, and it requires 333 ore units to refine. ... 1 Azure Plagioclase...

Plagioclase is actually a group of minerals. There is a continuous series from pure albite, NaAlSi3O8 (Ab), to pure anorthite, CaAl2Si2O8 (An). The series is arbitrarily divided into six species or subspecies as follows:

Plagioclase is the most common mineral in igneous rocks. The illustration to the left shows a large chalky white grain of plagioclase. The chalky appearance is a result of weathering of plagioclase to clay and this can often be used to aid in identification.
