A. (1976) Authigenic minerals in the PreCambrian sedimentary rocks of the Chattisgarh System (Central India). Metamorphic rock, which comes from the Greek to "change form," is formed by applying great pressure and temperature to existing rock converting it into a new distinct type of rock. The higher the temperature or pressure, the higher the grade of metamorphism. The Greek derivation of the word "geology" refers only to the Earth, but since the beginning of the space age, the field has expanded to include the study of the solid matter of other celestial bodies, such as Mars and the Moon.

The chemical material is carried in solution. This is the product of chemical weathering. The transportation versus deposition; in other words, the conditions that cause deposition of the chemical material depends upon the temperature of the water, the solubility of the particular substance that's dissolved, and also the water chemistry, meaning that interactions between one chemical and another may cause precipitation Tidal Signatures in Modern and Ancient Sediments (Special Publication 24 of the IAS) (International Association Of Sedimentologists Series) Tidal Signatures in Modern and Ancient Sediments (Special Publication 24 of the IAS) (International Association Of Sedimentologists Series) pdf, azw (kindle), epub.

If it breaks apart easily, it's cemented very loosely by clay minerals. Well, I hope that gives you a fairly good sense of the material. The next lesson we'll study metamorphic rocks, a rather extreme version of chemical change.

Sure, the forces, temperatures and timescales involved are orders of magnitude greater with rock, but the basic features of its plastic behavior are much the same. Its plasticity increases dramatically with temperature, especially near its melting point. At low temperatures, like those at the earth's surface, it becomes brittle enough that it would more likely fracture than flow if deformed rapidly ref.: Magic of Minerals and Rocks read for free click Magic of Minerals and Rocks pdf, azw (kindle), epub, doc, mobi.
