After halite precipitation, the residual brine (the bittern) is enriched in potassium–magnesium salts (K–Mg salts). The residual bittern is pumped from the pond 3 as the raw brine feed for pond 4. Through a brine mixing process, this highly saline brine is supersaturated with respect to epsomite and carnallite in ponds 4, 5, 6 and 7.Web

Grain Size. Detrital rock is classified according to sediment grain size, which is graded from large to small on the Wentworth scale (see figure).Grain size is the average diameter of sediment fragments in sediment or rock.
