Physical Geology Sed Rx Samples

Rock gypsum is a chemical precipitate formed by the evaporation of cencentrated solutions such as seawater It ranges in texture from massive/granular to fibrous depending on the size and shape of the gypsum crystals Sediment type: chemical; Composition: gypsum; Grain Size: varible, commonly fibrous or granular and medium to fine grained ; Common Sedimentary Environments: desert lakes

· WELL ROUNDED all corners of a grain are rounded off ; ANGULAR all corners of a grain are still sharp (pointed) The more the corners of an individual grain in a clastic rock are rounded, the longer the distance the grain has been transported 3) Sorting: Degree to which the sedimentary particles are the same size
