摘要
槐树坪金矿床位于华熊台缘坳陷熊耳山隆起,成矿区划属华熊台缘坳陷熊耳山隆起银、金、铜、铅、锌多金属成矿带,共发现13条构造蚀变带,圈出49个金矿体,矿体赋存于中元古界熊耳群火山岩中,受火山机构及NE向、NW向断裂联合控制,形态以脉状、透镜状、似层状为主,次为豆荚状、不规则状。通过对区域地质背景、矿区地质特征、化探异常特征等方面的研究,认为矿体受火山机构和断裂构造双重控制,并受后期热液叠加改造,属火山喷发-热液改造块状硫化物型矿床,探讨其矿床成因,归纳总结其找矿标志,以期为该地区寻找同类型矿床提供借鉴意义。
The Huaishuping gold deposit is located in Xiong’ershan uplift of Xiong Tai Long area of the North China platform.The metallogenic division belongs to the gold,silver,copper,lead and zinc polymetallic metallogenic belt of Xiong’ershan uplift in the marginal depression of Huaxiong platform.A total of13structural alteration zones were found,and49gold ore bodies were circled.The ore bodies occur in the Middle-Proterozoic Xiong'er Group volcanic rocks,controlled by faults trending NE and NW as well as by volcanic apparatus.The ore bodies take mainly the forms of vein,lenticular and banded,also have some lentil and irregular forms.Through the study of regional geological background,geological characteristics and geochemical anomaly characteristics,we think the ore bodies are controlled by volcanic apparatus and fracture structure,and reformed by superposition of late hydrothermal fluid,the deposit belongs to the volcanic eruption-hydrothermal reworked massive sulfide type,and summarizes signs for prospecting in order to find the same type of ore deposit in this area.It provides a reference for the research and exploration.
