Feldspar Facts for Kids
Feldspar is the name of a group of rock forming tectosilicate minerals that make up as much as 60 of the Earth s crust.. Feldspar forms crystals from magma in both intrusive and extrusive rocks and they can also happen as compact minerals as veins and are also present in many types of metamorphic rock.Rock formed entirely of plagioclase feldspar is known as anorthosite.
