દુર્લભ પ્લેજીયોક્લાસ્ટિક મૂનસ્ટોન ઘણા અગ્નિકૃત ખડકોમાં જોવા મળે છે,

anorthite's Usage Examples:

mostly composed of Ca-poor pyroxene, pigeonite, and Ca-rich plagioclase (anorthite).

It represents a plagioclase with less than 10% anorthite content.

solution of the endmembers K-feldspar [KAlSi3O8], albite [NaAlSi3O8] and anorthite [CaAl2Si2O8].

In minerals, as a feldspar, it can be found as anorthite, an end-member of the plagioclase series.

and silicates such as olivine, pyroxene, plagioclase feldspar (mainly anorthite), and garnet crystals.

characters it is intermediate between albite (NaAlSi3O8) and anorthite (CaAl2Si2O8).

The albite:anorthite molar ratio of oligoclase ranges from 90:10 to 70:30.

Its chemical formula is (Ca, Na)(Al, Si)4O8, where Ca/(Ca + Na) (% anorthite) is between 30–50%.

The two types of feldspar are usually: plagioclase: a member of the anorthite-albite series (CaAl2Si2O8-NaAlSi3O8) alkali feldspar: a member of the.

characteristic minerals in CAIs include anorthite, melilite, perovskite, aluminous spinel, hibonite, calcic pyroxene, and forsterite-rich olivine.

The series ranges from albite to anorthite endmembers (with respective compositions NaAlSi3O8 to CaAl2Si2O8), where.

described as a solid solution of the endmembers K-feldspar [KAlSi3O8], albite [NaAlSi3O8] and anorthite [CaAl2Si2O8].
