Rock gypsum grain size
-Most abundant grain size: sand-well sorted-well rounded grains-Clasts: mineral fragments ... -Rock gypsum-rock salt-ironstone-oolitic limestone-travertineBasically, beach material is small pieces of rocks that have eroded and have been carried to the beach via the wind and water. The geology of the surrounding area determines the color of those rocks. This determines what material is available for a beach. In Hawaii, much of the rock there is black basalt making the sand black on some beaches.
