Rock gypsum grain size
Gypsum, also known as calcium sulfate hydrate, is a naturally occurring mineral found in layers of sedimentary rock all over the world. It is formed by the evaporation and replenishment of waters containing calcium and sulfates.

Arbitrarily defined limits for the sizes of crystals within an igneous rock. Commonly accepted grain-size ranges are:For sedimentary rocks, see particle size.Composition & Types of Sand. Sand is a mixture of small grains of rock and granular materials which is mainly defined by size, being finer than gravel and coarser than silt. And ranging in size from 0.06 mm to 2 mm. Particles which are larger than 0.0078125 mm but smaller than 0.0625 mm are termed silt. Sand is made by erosion or broken pebbles ... ….

If water is the transport medium of sediment, the grain size of sedimentary deposits most closely indicates the _____. a. geographic extent of the weathering source rock at outcrop b. average velocity of the water from the time of erosion until deposition c. velocity of the water at the moment the sediment settled to the bottomClastic sedimentary rocks are classified according to the grain size of the sediment and the kinds of rock fragments that make up the sediment (Table ). Grain size is largely a function of the distance the particle was transported. In general, the greater the distance traveled, the smaller and more rounded the sediment particles will be.
Detrital sediments are classified by grain size. Detritus is classified by its grain size. Grains larger than 2 millimeters are called gravel.
