MINERAL COMPOSITION AND COLOR
"Rocks are made of mixtures of minerals and other materials. Some rocks contain only a single mineral. Others can contain several minerals. These minerals are known as rock-forming minerals.
A rock's color provides clues to the rock's mineral comp. For example, granite is generally a light-colored rock that has high silica content. Basalt, is a dark colored rock that is low in silica. But as with minerals, color alone does not provide enough information to identify a rock.
Geologists observe the shape and color of crystals in a rock to identify the minerals that the rock contains. In identifying rocks, geologists also use some of the tests that are used to identify mineral's. For example, testing the surface of a rock with acid determines whether the rock includes minerals made of compounds called carbonates."
