| 摘 要： | 万宝源斑岩型钼矿位于辽东裂谷内,产于石柱子花岗闪长岩体及其后侵入的石英斑岩内。矿化类型可以分为浸染状、细脉充填状和石英脉状三种。为了解决该钼矿的成矿流体来源及矿床形成机制问题,我们从流体包裹体、REE、S、D-O同位素入手进行了研究。石英中的流体包裹体测试数据揭示:钼矿化可以分为三个阶段,高温阶段、中温阶段和低温阶段,以中温阶段为主。REE分析表明,成矿物质起源于花岗闪长岩体,后经分离结晶作用,最终与花岗闪长岩体表现出不同的REE配分模式;S同位素分析显示,S来源于岩体与地层,是一种混合硫;D-O同位素研究则说明,成矿流体是以岩浆水为主,后期有天水加入的混合流体。最后建立石柱子成矿系统,对石柱子花岗闪长岩内外接触带上的矿床成因进行了探讨。

| Abstract: | Wanbaoyuan porphyry Mo deposit is located in Liaodong Rift and hosted by late Yanshanian Shizhuzi granodiorite body and later quartz porphyry.Mineralization types,according to host rocks and structure are divided into disseminated,veinlet-filled and quartz-vein ore.In order to solve the questions of ore-forming fluid source and ore-forming mechanism,fluid inclusions,REE,S and D-O stable isotope are studied.Vapor-liquid fluid inclusions data from quartz indicate that Mo mineralization experienced three stage... |
