| 摘 要： | 秦巴山区煌斑岩脉广泛分布,岩脉时代主要有加里东期、印支期、燕山-喜山期。大部分含金煌斑岩产于古生代地层中,主要是志留系和泥盆系的细碎屑岩类。本文主要讨论了秦巴山区煌斑岩与金成矿关系,并指出构造破碎作用在成岩成矿中的重要地位。脉体与围岩的同化混染作用、蚀变作用与氧化作用促使金的活化、迁移、富集成矿。

| Abstract: | The lamporphyre is Widely distribution in Qinba mountain areas, the agesare onacin Caledomian, Indosinian, yanshanian and Himalayan Most of the auriferous lam porphyre dike presented in palaeozoic and are mainly Devonian and Silurian and their wall rock are essentially repres ented by fine clastic rock. In this paper, the relation between the lamporphyre Char-acteristics and gold mineralization are discussed. It is suggested that structure fracture have played a very im portant part in diagenesis and ore formation. Alteration, assimilation Contamiation and oxidation of dikes enable the gold easy to activate, migrate, and enrich under suitable metallogenlc conditions. |
