Some Physical-Chemical Fundamentalstion, “When does a crystal crystallize from a melt?”. The obvious answer is that it occurs when a fluid is cooled a bit below the melting temperature (melting point) which prevails at some definite pressure. In order to determine the exact melting point in those cases where it is not possible to dir

Sedimentary Rocksnts are water, wind, and ice, and in rare instances organisms. Deposition takes place under the influence of gravity, as a result of settling, flocculation, and chemical precipitation, the latter either directly or through the action of organisms. Likewise evaporite deposits are sediments because th

Metamorphic Petrogenesisering processes on the one hand and complete remelting on the other. Such transformations can occur through changes in temperature and pressure alone. Load pressure, resulting from the superposition of later-formed rocks, is sufficient to accomplish metamorphism. Under normal conditions in the upper

Geochemical Considerationse earth’s crust. Thus, we have observed a cycle of processes starting with magmatic crystallization, leading to weathering, sedimentation, and finally metamorphism, which can lead in turn to the generation of new magmas. In dealing with this so-called rock cycle (or geochemieal cycle) we have, in fa
