k feldspar microstructures

Shock melting of K-feldspar and , - sciencedirect

The K-feldspar microstructures in the granitic rocks of the Toqqusap Nunaa area are characterised by ubiquitous, highly irregular grains with highly variable sizes and numerous cusps, saddles, and branches, which are located along the margins of deformed aggregates of quartz and, especially, interlaced with fractured and ,

ALEX STREKEISEN-Feldspar structure-

Feldspar The name feldspar derives from the German words Feld, "field", and Spath, "a rock that does not contain ore" Feldspars are the most abundant mineral in the Earth's crust, making up more than 60% of both the continental crust and the oceanic crust
