Sedimentary rocks were formed from particles or dissolved materials from older rocks. 4. Basalt and granite are examples of metamorphic rocks. 5.Gypsum rock has an obvious layered crystal structure with the increase of CaSO 4 ·2H 2 O, contributing to the phenomenon with a larger grain size and lower tensile strength.Grain size is the average diameter of sediment fragments in sediment or rock. Grain sizes are delineated using a logbase-2 scale [ 9 ; 10 ]. For example, the grain sizes in the pebble class are 2.52, 1.26, 0.63, 0.32, 0.16, and 0.08 inches, which correlate respectively to very coarse, coarse, medium, fine, and very fine granules.
