摘　　要：我国是全球第一大锂资源消费国,但供应能力较弱,对外依存度高达80%,政府相关部门高度重视锂资源勘查工作。河南地勘二院2016-2018年在新疆托盖勒克托盖勒克地区开展的化探扫面工作中,圈定了三个以Li为主成矿元素的化探综合异常,通过槽探工程验证发现了资源潜力巨大的托盖勒克锂矿点。作者通过对研究区化探测试数据进行综合处理分析,总结出该区的地球化学特征和锂矿找矿前景。锂矿主要赋存于锂云母伟晶岩脉内、目前发现地表矿化体4条,锂平均品位1.07%,初步估算矿床达到大型规模,具有形成超大型锂稀有多金属矿的找矿前景。China is the world’s largest consumer of lithium resources, but its supply capacity is weak and its dependence on foreign countries is as high as 80%. Relevant government departments attach great importance to the exploration of lithium resources. In 2016-2018, the second Institute of geological exploration of Henan province carried out the geochemical exploration work in togalek, Xinjiang. Three comprehensive geochemical anomalies with Li as the main ore-forming element were delineated. Through the verification of the trenching project, the tongalek lithium ore spot with huge resource potential was found. Through the comprehensive processing and analysis of the geochemical test data in the study area, the author summarizes the geochemical characteristics of the area and the prospect of lithium exploration. At present, there are 4 surface mineralized bodies found in the vein of lepidolite pegmatite. It is estimated that the deposit has reached a large scale in rough steps, and it has the prospect of forming super large rare lithium polymetallic ore.
