Feldspar - an overview | ScienceDirect Topics

The feldspar fuses when it melts, forming a glass matrix. The feldspars are mixtures of potassium alumino-silicate (K 2 O Al 2 O 3 6SiO 2) and sodium alumino-silicate, also known as albite (Na 2 O Al 2 O 3 6SiO 2). Feldspars are naturally occurring substances, so the ratio between the potash (K 2 O) and the soda (Na 2 O) will vary somewhat.

Pictures and Descriptions of Igneous Rock Types

03-06-2019· Igneous rocks are those that form via the process of melting and cooling. If they erupt from volcanoes onto the surface as lava, they are called extrusive rocks.By contrast, Intrusive rocks are formed from magma that cools underground. If the intrusive rock cooled underground but near the surface, it is called subvolcanic or hypabyssal, and often has visible, but tiny mineral grains.
