Sedimentary Rock Classification ( Read ) | Earth .

Clastic Sedimentary Rocks. Clastic sedimentary rocks are grouped by the size of the sediment they contain. Conglomerate and breccia are made of individual stones that have been cemented together. In conglomerate, the stones are rounded. In breccia, the stones are angular. Sandstone is made of sandsized .

Texture nonclastic. Grain size cryptocrystalline, cannot be seen except under very high magnification. Hardness hard. Colour all colours, dependent on impurities present when precipitated. Clasts none. Other features smooth to touch, glassy, exhibits conchoidal fracture. Uses mainly decorative; ancient cultures used chert for cutting tools, arrow heads etc.

Kinetics of precipitation of gypsum and implications for

an almost identical dependence on applied stress and grain size, supporting the hypothesis that pressuresolution creep in gypsum is controlled by the kinetics of precipitation. Keywords: kinetics, gypsum, pressure solution, deformation, compaction. On the basis of both field and laboratory studies, it is wellestablished that gypsum is one of the weakest and most ductile rock materials found

Dehydration of Gypsum Rock by Solar Energy: Preliminary Study

To study the influence of the grain size in the transformation of dihydrate calcium sulfate phase into bassanite and anhydrite, the gypsum rock was crushed at different particle sizes. The particle size distribution of the ground sample is collected in Figure 3. For the proposal of this work, only major fractions were used.
