What is Perthitic texture?
Likewise, people ask, what is Exsolution?
Exsolution is a process by which a solid solution phase unmixes into two separate phases in the solid state. Exsolution occurs only in minerals whose compositions vary between two or more pure endmember compositions.
One may also ask, which feldspar is pink? Orthoclase
Also know, which feldspar has exsolution lamellae?
Perthite is used to describe an intergrowth of two feldspars: a host grain of potassium-rich alkali feldspar (near K-feldspar, KAlSi3O8, in composition) includes exsolved lamellae or irregular intergrowths of sodic alkali feldspar (near albite, NaAlSi3O8, in composition).
What are alkali feldspars?
Alkali feldspar, any of several common silicate minerals that often occur as variously coloured, glassy crystals. In the Earth's crust the alkali feldspars display a range of ordering from the fully random distribution of sanidine and orthoclase to the fully ordered distribution of microcline. See feldspar.
