Gypsum grain size.

Quartz is, by far, the dominant mineral in sandstones. Still there are other varieties. A Quartz arenite – is nearly 100% quartz grains. An Arkose contains abundant feldspar. In a lithic sandstone, the grains are mostly small rock fragments. A Wacke is a sandstone that contains more than 15% mud (silt and clay sized grains)..

The three gypsum transects are labeled numbers 1, 2, and 3.At the rock scale, the variability of gypsum facies all over the world (with differences in grain size, porosity, gypsum content and rock structure) results in a broad range of values of ...The grains will elongate in a direction that is perpendicular to the direction of compressive force. This alignment and increase in mica grain size gives the rock a silky luster. At that point the rock can be called a "phyllite." When the platy mineral grains have grown large enough to be seen with the unaided eye, the rock can be called "schist."

It consists of the mineral gypsum with a very fine grain, massive habit, and even coloring. Alabaster is also used to refer to a similar type of marble, ... a sedimentary rock composed mostly of the mineral chalcedony—cryptocrystalline silica in crystals of submicroscopic size.This leads to such features of molded gypsum products as smooth surface, accurate size, distinct and plump edges and corners, and refined decorative effects.
