Feldspar | Earth Sciences Museum
The term feldspar is used to identify a very large group of minerals. In fact, it is used to describe any mineral which consists of framework aluminum, oxygen and silicon atoms plus an additive. All minerals in this grouping have the same crystalline structure. The feldspar group has nearly 20 recognized members, but only nine of those are common.
What Are The Uses Of Feldspar?
Feldspar minerals account for the largest percentage of minerals in rocks, and a glassy mineral in a rock slightly softer than quartz is likely to be part of the feldspar family. Types of Feldspar.
