Feldspar HyperPhysics Concepts

Feldspar is a name given to a class of aluminumcontaining silicates which are sometimes called light silicates or "nonferromagnesian silicates" since they don't contain iron or magnesium. The feldspars include orthoclase (KAlSi 3 O 8 ) and plagioclase ((Ca,Na)AlSi 3 O 8 ).

Milky quartz is a common mineral that is found in many different types of rocks. The chemical formula is Silicon oxide (SiO2). One type of quartz is easily identified by its hexagonal crystals, but quartz can also be found in a large mass. Quartz can be broken or weathered into the tiny pieces we know as sand.
