PETROCHEMICAL AND GEOCHEMICAL CRITERIA PGE-BEARING OF ROCKS VURUCHUAIVENCH MASSIF (MONCHEGORSK PLUTON, MURMANSK REGION)

Questions of terminology and classification of hydrothermal fluid processes as well as their differences from the karst are considered in the article. Diagnostics criteria of karst processes, differences of hypergene karst from hydrothermokarst are shown. An option of specification such definitions as tuffisite, флюизитов, fluidolith, structures of the gas permeability is suggested. Characteristics generalization of various fluid processes is attempted. The conclusion about the existence of a wide spectrum of translayer no magmatic processes, having specific parameters and scales, as well as mineral deposits complex is made.

Keywords: karst, hydrothermokarst, fluidolith, tuffisites, zone of deep gas permeability, criteria, mineralization
