西藏冈底斯东段成矿系列区域地球化学预测

Regional geochemical prediction of the minerogenic series in the eastern section of the Gangdise Mountains,Tibet

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。

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 mineraliza - tion 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.
