| 摘 要： | 金矿化是一个复杂的地质作用过程,是多种地质作用密切配合所完成。四川若尔盖北部拉日玛-邛莫金矿带的形成,是地质构造从地壳浅部构造层次逐渐抬升至地表;岩石从脆-韧性变形演化到脆性变形;矿源层中的有机碳从低成熟度演化到高成熟度;岩石中的金从惰性金演化为活性金;地层中的金从初步富集演化形成金矿床。地质构造演化促使地层中的有机物演化,促使金的初步富集到形成金矿床。因此,构造演化、有机物演化、成矿演化三者密切相关。

| Abstract: | Gold mincra;ozatopm is a very complex geological process and calls for close coordination of varied geological processes.Gold deposits in the gold mineralization belt in the northern part of Zoige, Sichuan, were formed through gradual uplift of geological structures from, the shallow levels of the crust to the surface, deformation of rocks from brittle-ductile to brittle one, evolution of organic carbon in source beds from low to high maturity, evolution of gold in the rocks from nert to activated one and gradual concentration of gold from strata. The tectonic evolution promoted the evolution of organic carbon in strata and concentration of gold. Here there are intimate relationships among tectonic evolution, organic evolution and metallogenic evolution. |
