Rock gardens are low-maintenance, easy to design, and can be customized to fit any size or style of yard.Mined gypsum contains both quartz and dolomite [CaMg(CO₃)₂]. FGD gypsum usually possesses a much smaller and more uniform particle size (more than 95% < 150 microns) than agricultural mined gypsum that is granulated to produce a final size of 2–4 mm. However, FGD gypsum can also be processed to form larger-sized granules.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.Download Table | Chemical analysis by XRF of initial gypsum for the different grain size fractions (oxides wt%). from publication: Dehydration of Gypsum Rock by Solar Energy: Preliminary Study ...

Clastic sedimentary rocks have particles that range in size. Their names are based on the grain size and are categorized into three main groups: clay (less than 1/16 mm), sand (1/16 – 2 mm), and gravel (larger than 2 mm).
