摘要

冈底斯成矿带经历的地质演化过程极为复杂

并由此产生了一系列规模巨大的多金属成矿带

其中以超大型的钼铜多金属矿为特色。采用地史与构造方法对冈底斯成矿带东段的地球动力学成因进行了梳理

并通过LA-ICP-MS锆石U-Pb年代学测定及

Ar-

Ar同位素定年方法对沙让钼矿的成矿机制进行了分析。结果表明

冈底斯东段发生的5期钼成矿事件均与燕山晚期的酸性岩浆活动和喜山早期的中酸性岩浆侵入有关。

Abstract

Due to the complex processed of geological evolution in the Gangdese metallogenic belt

it was formed a series of large scale polymetallic metallogenic belts

and among of them are super-large molybdenum-copper polymetallic deposits.This study were used geological history and tectonic method to discussed the geodynamic formation of the east part of the Gangdese metallogenic belt

also discussed the metallogenic mechanism of Sharang molybdenum deposit by using LA-ICP-MS zircon U-Pb chronology and

Ar-

Ar isotope chronology dating method. The resulted showed that 5 stages molybdenum mineralization events were occurred in the eastern part of Gangdese

which were related to the acidic magmatism of Late Yanshan and the intermediate

-acidic magmatism of Early Xishan.
