Rock gypsum grain size

The rock salt is mined, crushed to appropriate size, and usually applied to roads and highways without further processing. When applied dry, much of the salt can bounce off of the road or be scattered by the wind of passing traffic. If the salt is applied wet, more of it sticks to the road, and the loss of salt is reduced..

Texture (grain size) Coarse (over 2 mm) Medium (1/16 to 2 mm) Fine (1/16 to 1/256 mm) Very Fine (less than 1/256) Composition Calcite Quartz Gypsum Halite Altered plant fragments Clastic Sedimentary Rocks Sediment Name Gravel (rounded fragments) Gravel (angular fragments) Sand Mud Mud Chemical Sedimentary Rocks Texture (grain size) 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.
