摘要:
提要:西藏冈底斯东段优势矿床成矿系列预测是当前需要解决的重要问题。文中研究了成矿系列矿源场特征,以及地球化学靶区与矿床成矿系列的联系,揭示了矿化规模的地球化学控制因素,计算了因素耦合系数。预测冈底斯构造带是4种类型矿床成矿系列的密集区。

Abstract:
Abstract:The prediction of preponderant minerogenic series in the eastern section of the Gangdise Mountains, Tibet, is a key problem that needs to be solved currently. The authors studied the provenance characteristics and relations between geochemical targets and minerogenic series, revealed the geochemical constraints of mineralization scale and calculated factors coupling coefficients for predicting potential resources. It can be concluded that four different minerogenic series are concentrated in the eastern section of the Gangdise Mountains.
Key words:  minerogenic series prediction  constraint  factors coupling coefficient  Gangdise Mountains
