摘要
动力变质作用对金矿有直接的成矿意义。动力变质过程就是成岩成矿过程,不同程度的动力变质相带金的迁移、富集规律不同,形成的矿石建造也有差异。动力变质作用中岩石力学变形梯度不一定都与深度有关,常因岩性和应力集中面分布不均一,水平方向脆性—韧性应变带相间出现。
The dynamic metamorphism has a direct association with the gold mineralization. The process of dynamic metamorphism is homogeneous with that of diagenesis and minerogenesis. The regularities of migration and enrichment of the gold vary in different grade of dynamometamorphic facies belts. The gradient of mechanic deformation of rocks is not necessarily related with the depth. The horizontal brittle - plastic stress zones appear Iternatively due to the inhomogeneous distribution of lithology and stress concentration plane.
