dc.description.abstract | In term of geological position and conditions of formation with use of a modern geodynamic basis 5 types of pyrophyllite deposits are established. First and second are connected to hydrothermally altered rocks in acidic and intermediate volcanogenic suites. Its differ by character of metasomatites and their subsequent transformations in various volcanic conditions. The third type includes deposits and occurences of metamorphogenic-metasomatic genesis and is caused by transformations of a green-shist facies of terrigenoussedimentary interbeds among volcanites of acidic composition. The fourth type is connected to low and mid-temperature stages of formation of hydrothermal veins within the limits of volcanogenic and metamorphic stratums. The deposits of weathering crusts on metamorphic stratums and metasomatites, containing a pyrophyllite mineralization concern to the fifth type. | |
