    Reading Mining and Mineral Use Geology

    Rocks are crushed so that the valuable minerals can be separated from the waste rock. Then the minerals are separated out of the ore. A few methods for extracting ore are: heap leaching: the addition of chemicals, such as cyanide or acid, to remove ore. flotation: the addition of a compound that attaches to the valuable mineral and floats.

    The Factors That Control Metamorphic Processes GeologyIn

    The parent rock or protolith is the rock that exists before metamorphism starts. It can be any of the three rock types: sedimentary, igneous, or metamorphic. The critical feature of the parent rock is its mineral composition . This is because the stability of minerals (how influenced they are by changing conditions) is what counts when metamorphism takes place.

    How X rays helped to solve mystery of floatingrocks

    It’s true—some rocks can float on water for years at a time. And now scientists know how they do it, and what causes them to eventually sink. X-ray studies at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have helped scientists to solve this mystery by scanning inside samples of lightweight, glassy, and porous volcanic rocks known as pumice stones.

    Texture of a rock is the appearance of the rock and how one feels touching it. The size and shape of the mineral grains or crystals and the pattern of their arrangement give a texture to the rock. The texture of a rock provides a clue whether the magma cooled fast or slowly and where the rock was formed.
