WebAluminosilicate. Aluminosilicate refers to materials containing anionic Si-O-Al linkages. Commonly, the associate cations are sodium (Na + ), potassium (K +) and protons (H + ). Such materials occur as minerals and as synthetic materials, often in the form of zeolites. Both synthetic and natural aluminosilicates are of technical significance as ... Web1Classification and nomenclature of volcanic rocks Petrographic analysisis carried out first based on core data, geochemical analysis, and thin section information. This is followed by the identification and classification of volcanic rocks using the “component + texture + genesis” scheme.

The major secondary phyllosilicates in soil are summarized in Table … In ore deposit geology, supergene processes or enrichment are those that occur relatively near the surface as opposed to deep hypogene processes. Supergene processes include the predominance of meteoric water circulation (i.e. water derived from precipitation) with concomitant oxidation and chemical weathering. The descending meteoric waters oxidize the primary (hypogene) sulfide ore minerals and redistribute the metallic ore elements. Supergene enrichment occurs at the base of … incfile expedited filing
