摘要
秦岭造山带经历了逆冲推覆构造运动,同时有酸性岩浆侵入活动,进而形成了与花岗岩浆活动相关的金、银、铜、钼多金属矿化带。在东秦岭的小秦岭-熊耳山金矿集区内,发育有东闯、文峪、大湖、祁雨沟、上宫、北岭、桐沟等典型矿床。除此之外,北秦岭的阳山、镰子沟、庞家河、凤太多金属矿集区以及“勉略宁”三角区也有金矿产出;西南秦岭的金矿床大多形成于印支期,如马鞍桥、夏家店、柞水-山阳矿集区、铧厂沟、李子园、八卦庙、镇甸盆地等共同构成了秦岭造山带西部金矿集区。本研究以秦岭全域金矿为研究对象,系统梳理了秦岭造山带金矿的时空分布、成矿流体特征及成矿模式。重点以小秦岭-熊耳山矿集区为例,通过统计前人的实验方法和研究成果,归纳秦岭造山带金矿的特征信息与研究方法;结合流体包裹体、同位素地球化学等手段,揭示了该区金矿多期次叠加成矿的特征,旨在对研究区金矿进行系统的总结与分类。
Abstract
The Qinling orogenic belt undergone thrust nappe structure and accompanied acid magmatic intrusion, forming gold, silver, copper and molybdenum polymetallic mineralization belt related to granite magma activity. The Xiaoqinling-Xiong'ershan gold deposit cluster located in the eastern Qinling is the second largest gold deposit cluster in China after Jiaodong. The typical deposits developed in Dongchuang, Wenyu, Dahu, Qiyugou, Shanggong, Beiling and Tonggou. In addition, there are gold deposits in Yangshan, Lianzigou, Pangjiahe, Fengtai polymetallic belt and 'Mian-Lue-Ning' triangle area in northern Qinling; the gold deposits in western and southern Qinling mostly formed in the Indosinian period, with Ma'anqiao, Xiajiadian, Zhashui-Shanyang gold deposit cluster, Huachanggou, Liziyuan, Baguamiao, Zhendian basin tectonic Qinling orogenic belt western gold deposit cluster. In this study, the spatial and temporal distribution, ore-forming fluid characteristics and metallogenic model of gold deposits in Qinling orogenic belt sorted out systematically. Taking the Xiaoqinling-Xiong'ershan gold deposit cluster as an example, the characteristic information and research methods of gold deposits in Qinling orogenic belt summarized by counting previous experimental methods and research results. Combined with fluid inclusions, isotope geochemistry and other methods, the characteristics of multi-stage superimposed mineralization of gold deposits in study area are revealed, aiming at summarize and classify the gold deposits systematically.
