| 摘 要： | 迭部刀扎—舟曲憨班一带已发现金矿床(点)与桑坝推覆体构造前缘的采古逆冲断裂具有密切的关系。该断裂不仅控制了含矿地层、岩浆岩的分布,而且是区内重要的控矿、容矿断裂。有规模的金矿体一般产在岩体的接触带上。金矿化与硅化、黄(褐)铁矿化、黄铜矿化关系密切。由此而提出了在该区带进一步找矿的主要地质标志。

| Abstract: | The known gold deposits(occurrances)found in the area from Daozha of DiebuCounty to Hanban of Zhouqu County are closely associated with Caigu thrusted fault in the frontborder of Sangba Nappe.Caigu fault not only controls the distribution of ore-bearing strata andmagmatic rocks,but is the important ore-controlling and ore-hosting structure.Important goldore bodies generally occur in the contact zone of rock bodies and country rocks.Gold mineralizationis closely related to silicification,pyritization (limonitization)and chalcopyritization.Geological in-dicotors for gold ore prospecting in the area are put forward. |
