Weathering and Soil Mineral Formation
The petrogenetic processes which produce new mineral assemblages, either by alteration of previously formed rocks, or by recombination of alteration products, are quite different from those which produce igneous rocks. Those alteration processes which take place at the surface of the earth, at the earth-atmosphere interface, are called weathering processes. Weathering products formed in situ without transport form soils; following transport they form sediments. Alteration of previously formed rocks which takes place at depth or at the surface as a result of magmatic influence is considered a part of the meta-morphic process.
