Rock-Forming Minerals

Rock Forming Minerals

QUARTZ

We learned that rocks are formed from minerals. Two of the most common are Quartz and Feldspar.
Quartz can be found in any type of rock, it is a very old minerals that can be found in any rocks no matter how ancient. Since quartz can be found anywhere it is called "tramp" mineral.

As empr gov:

While rocks consist of aggregates of minerals, minerals themselves are made up of one or a number of chemical elements with a definite chemical composition.

FELDSPAR

Feldspar is a very common mineral just like quartz, Different kind of feldspar has different colors, some kind are used as gemstone, some is transparent. All kinds of feldspar have a glassy or pearly appearance. The gem variety of feldspar can be found in Switzerlamd, Norway, Siberia, Madagascar, Pennsylvania, Virginia and Colorado.

Hope we learned something. :)
