摘要
硫、铅同位素研究表明,金矿成矿作用具有明显的继承性.区域潜在含金性是形成金矿化集中区的首要前提,花岗岩类侵入体和韧性剪切带的形成是造成矿源层(岩)中金活化的主要营力.正常的岩浆结晶分异作用难以形成含金热液,通过二次活化再成矿是金矿成矿的主要机制.在成因上同时与太古宙绿岩建造和显生宙花岗岩类有关的一系列金矿床构成了地台区特有的金矿床系列.
Studise of sulphur & lead isotope have shown that there exists a remarkable inheritance in gold mineralization. The potential gold-bearing nature of certain region is the major premise of the formation of gold mineralization concentrate zones. The intrusion of granites & ductile shear zone are the main agents for the gold remobilization from source bed (rock). The common differentiation of magmatic crystallization is diffecult to generate auriferous hydrothermal solution. The basic mechanism of gold metallogeny is characterized by double remobilization & concentration of gold. A series of gold deposits related to both Archaen green stone formation & Phanerozoic granites constitute the characteristic gold deposit series in platforms.
