Pale blue to blue-green shales typically are rich in carbonate minerals. Clays are the major constituent of shales and other mudrocks. The clay minerals represented are largely kaolinite, montmorillonite and illite.Shale is usually gray to black. It is usually composed of clay minerals and quartz grains. However, additional elements in the rock often give it different colors. For example, ferric oxides impart red, brown, or orange color. The exact color due to iron oxide depends on the type of oxide in the rock. Hematite (ferric oxide) gives a red color ...
