【摘要】：内蒙古科尔沁右翼中旗哈嘎屯地区位于大兴安岭中南段东缘,是西伯利亚与中朝板块之间对接碰撞后形成的中—晚期华力西地槽的一部分。晚侏罗世断裂活动加剧,在燕山早期,大规模火山—岩浆侵入活动形成了北东向构造—岩浆带。深源岩浆为成矿提供了热源和成矿物质,形成了著名的大兴安岭铜、铅、锌、银、锡多金属成矿带。设计工作区处于该多金属成矿带之林西—扎兰屯成矿亚带上,在古生代属西伯利亚板块东南陆缘增生带和华北板块北部陆缘增生带,从中生代开始成为欧亚板块东缘的一部分,受滨西太平洋强烈影响,成为滨西太平洋火山-岩浆岩带的一部分。其Ⅰ级成矿带属古亚洲成矿域的东段及古亚洲成矿域与滨(西)太平洋成矿域叠加复合部位。古亚洲成矿域与滨太平洋成矿域叠置,多期成矿叠加,增强了成矿的强度。根据大地构造背景和已知矿床(孟恩陶力银铅锌矿床、莲花山铜矿床、布敦花铜矿床等)的分布及其形成的地质构造条件分析,该地区具有良好的找矿前景。在前人工作的基础上,对资料进行系统整理分析,以钻探为主要手段,对区内已发现多条矿化蚀变带、激电中梯异常、铀矿化点以及含矿海西期花岗岩岩体进行评价其成矿潜力;对上侏罗统满克头鄂博组与海西晚期侵入岩接触带部位进行大比例尺的地质、物探测量,寻找新的矿化信息以及深部激电异常体,逐步扩大找矿靶区,为下一步工作提供依据。本文以铀及多金属找矿理论为指导,对成矿有利地段进行评价,注重矿点突破,兼顾外围,对2015年工作(项目实施、组织管理、经费、质量及安全保障情况)行了详细部署。
[Abstract]:The Hagatun area of Horqin Middle Banner is located in the eastern margin of the central and southern section of Daxing'anling Mountains, Inner Mongolia. It is a part of the late Huaxi geosyncline formed by the docking collision between Siberia and China and Korea. The late Jurassic fault activity intensified in the early Yanshanian. The large-scale volcano-magmatic intrusions formed the NE-trending tectonic-magmatic zone. The deep magma provided the heat source and ore-forming material for the mineralization, and formed the famous copper, lead, zinc and silver in the Daxinganling Mountains. The design work area is located in the Linxi-Zalantun metallogenic subzone of the polymetallic metallogenic belt, which belongs to the southeastern accretive zone of Siberian plate and the northern margin of North China plate in Paleozoic. It became part of the eastern margin of the Eurasian plate from the Mesozoic and was strongly influenced by the western coast of the Pacific Ocean. It is a part of the volcanic-magmatic belt in the West Coast Pacific Ocean. Its grade I metallogenic belt belongs to the eastern segment of the Paleo-Asian metallogenic domain and the Paleo-Asian metallogenic domain and the shore-based (western) metallogenic belt. The superposition of the Pacific metallogenic domain. The paleo-Asian metallogenic domain and the riparian Pacific metallogenic domain are superimposed. The multi-stage metallogenic superposition enhanced the metallogenic strength. According to the tectonic setting and known deposits (Menn Taoli Ag Pb Zn deposit Lianhuashan copper deposit). The distribution of Buduhua copper deposit and the geological structural conditions of its formation show that the area has a good prospecting prospect. On the basis of the previous work, the data are systematically analyzed and drilled as the main means. The ore-forming potential of several mineralization alteration zones, induced medium ladder anomalies, uranium mineralization points and ore-bearing Hercynian granitic rocks has been evaluated in this area. The contact zone between the upper Jurassic Mankitou Obo formation and the late Hercynian intrusive rocks was measured on a large scale, geophysical prospecting was carried out, new mineralization information and deep IP anomaly were searched for, and the prospecting target area was gradually expanded. This paper, guided by uranium and polymetallic prospecting theory, evaluates the favorable ore-forming areas, pays attention to the breakthrough of ore points, takes into account the periphery, and works on 2015 (project implementation, organization and management). Detailed arrangements are made for funding, quality and safety.
