【摘要】：研究区位于中条山元古代岛弧带的西南部,南接汾渭裂谷带。区内出露的地层以前寒武纪地层为主,本次研究主要涉及下元古界中条群和担山石群。中条群岩性主要为云母片岩和大理岩,其中篦子沟组为胡-篦型铜矿床含矿层位,局部有金、银、铅、锌矿化,局部形成矿床;担山石群主要由砾岩和石英岩组成。区内历经了悠久的地质历史,多期次的构造运动和强烈的岩浆活动。区域重力、航磁及地球化学资料显示中条山中南段有良好的找矿前景。论文在分析区域成矿规律和成矿系列的基础上,选择了中条山中南部柳木桌-瓦渣沟地区、七峪-柳仙洞地区及刘家岔-锥子山地区三个重点研究区进行了岩石地球化学研究。研究表明:Cu元素最大值893.8×10-6,平均29.18×10-6,标准离差12.26,变异系数0.42,主要高值区有2处。Au元素最大值135×10-9,平均1.26×10-9,标准离差0.60,变异系数0.48,有柳木桌、瓦渣沟、贺峪沟、峪口等多个浓集中心。Ag元素最大值5×10-6,平均0.07×10-6,标准离差0.03,变异系数0.428,主要高值区有3处。通过成矿作用、成矿模式及找矿标志的研究,结合地质条件、地球物理、地球化学和遥感等特征,利用类比分析的方法,本文共圈出了柳木桌-贺峪沟、老君庙-锥子山、七峪-柳仙洞3个找矿靶区。
[Abstract]:The study area is located in the southwest of the Proterozoic island arc belt of Zhongtiaoshan and the Fenwei rift belt in the south. The protruding strata in the area are preCambrian strata, this study mainly involves the Zhongtiao Group and the Tanshanshi Group of the Lower Proterozoic. The lithology of Zhongtiao Group is mainly composed of mica schist and marble, in which the Bizigou formation is the ore-bearing horizon of Hu-grate type copper deposit, with local gold, silver, lead, zinc mineralization and partial formation of deposits, while the Tan-shanshi group is mainly composed of conglomerate and quartzite. The area has undergone a long geological history, multiple tectonic movements and strong magmatic activity. The regional gravity, aeromagnetic and geochemical data show that there is a good prospecting prospect in the central and southern part of Zhongtiao Mountain. On the basis of the analysis of regional metallogenic regularity and metallogenic series, three key research areas, namely, Liumao-wajagou area, Qiyu-Liuxiandong area and Liujiacha-pyanzishan area, in the central and southern part of Zhongtiao Mountain, have been selected for the study of rock geochemistry. The results show that the maximum value of the element is 893.8 脳 10 ~ (-6), the average is 29.18 脳 10 ~ (-6), the standard deviation is 12.26, the coefficient of variation is 0.42, the maximum value of .au is 1.26 脳 10 ~ (-9) in the main high value region, the standard deviation is 0.60, the coefficient of variation is 0.48. The maximum value of element. AG was 5 脳 10 ~ (-6), average 0.07 脳 10 ~ (-6), standard deviation 0.03, coefficient of variation 0.428, and three main high value regions. Through the study of metallogeny, metallogenic model and prospecting markers, combined with the characteristics of geological conditions, geophysics, geochemistry and remote sensing, and by using the method of analogy analysis, this paper has formed a total of Liumutable-Heyugou, Laojunmiao-pyanzishan, etc. Qiyu-Liuxiandong three prospecting target areas.
