Study on geochemical composition and isotope ages of the Malasongduo porphyry associated with Cu-Mo mineralization

  • 马拉松多斑岩铜钼矿床是玉龙斑岩铜矿带中第二大的大型斑岩铜钼矿床,本文分析了岩体化学组成及用锆石LA-ICP-MS U-Pb法以及黑云母K-Ar法测定了成岩成矿体系同位素年代。赋矿岩体可分为早晚两期, 早期岩体主要由石英二长斑岩及碱长花岗斑岩组成,晚期岩体主要由碱长花岗斑岩组成。早期岩体和晚期岩体在化学组成上有一定的差异,早期岩体富Al2O3、MgO、CaO、Na2O、Fe 2O3、TiO2,晚期岩体则相对富SiO2及K2O;马拉松多早期岩体锆石LA-ICP-MS U-Pb年龄(36.9±0.4Ma, MSWD=1.52)与晚期岩体锆石LA-ICP-MS U-Pb年龄(36.9±0.3Ma, MSWD=1.38)相同,也和黑云母K-Ar年龄(36.9±0.6Ma)及前人的辉钼矿Re-Os年龄一致。早期和晚期岩体是在现有同位素体系难以区别的相同的时间间隔内脉动侵入形成的,马拉松多成岩成矿系统在很短时期内从高温(800℃,锆石U-Pb封闭温度)冷却至中低温(300℃黑云母Ar同位素体系的封闭温度),成岩成矿时间跨度小于1Ma。玉龙矿带主要赋矿岩体锆石年龄表明,玉龙斑岩铜矿带岩浆活动时间跨度4.3Ma内,约发生过四次成岩成矿事件。
