Minerals Present In Rocks

Extracting ores Mining of mineral resources

Rocks with large concentrations of minerals are called ores Mining depends on finding good quality ore preferably within a small area The next step is to get the rocks which contain the mineral out of the ground Once the ore is on the surface the process of getting the mineral you want out of the rock

Metamorphic Rocks Geology

Much as the minerals and textures of sedimentary rocks can be used as windows to see into the environment in which the sediments were deposited on the Earth s surface the minerals and textures of metamorphic rocks provide windows through which we view the conditions of pressure temperature fluids and stress that occurred inside the Earth during metamorphism The pressure and temperature

Exercises on Igneous Rocks Introductory

The classification of an igneous rock depends partly on the minerals that may be present in the rock and since the minerals have certain colours due to their chemical makeup then the rocks must have certain colours For example a rock composed of mostly olivine will be green in colour due to olivine s green colour such a rock would be called ultramafic A rock that has a large amount of
