与深断裂有关的近断裂变质作用及其成矿体系

根据在乌拉尔和哈萨克斯坦的研究成果，系统论述了近断裂变质作用形成时的大地构造环境和构造条件，及其在地壳和上地幔各深度段中的发育特点和表现形式、近断裂变质带中金属矿化的特点，并讨论了研究近断裂变质作用对非传统型金属矿床成矿预测和找矿的意义。

THE NEAR-FAULT METAMORPHISM CONNECTED WITH DEEP FRACTURES AND ORE FORMATION SYSTEM

The main features of near-fault metamorphism are developing in narrow drainage structures of displacing nature and arising as a result of block dislocatinns during late-and postorosenic development stages of geosynclinal-folded regions. The near-fauit metamorphism connected with deep fractures has progressive and resressive branches and in regard to factes level it reaches high stages up to magma formation in the stream of ascending intratelluric solutions. Concerning geochemistry, the near-fault metumorphism is characterised by many petrogenic and ore elements supplied from deep, still thermally active section of the Earth crust and the upper mantle including intensive local redistribution of chemical elements with formation of various metal concentrations.
