冈底斯中部位于西藏高原腹地,地理位置和构造—成矿带所处的位置十分重要,大地构造位于拉萨—冈底斯陆块中部.中新生代在班公湖-怒江特提斯洋向南俯冲、雅鲁藏布江洋向北俯冲、碰撞构造背景制约下,产生了强烈的构造运动和大规模的岩浆活动,为成矿提供了强大的热动力;多期次火山、岩浆热液的参与,为成矿提供了丰富的物质来源,有利的成矿地质背景从宏观上控制了区内金属矿产的形成.本文在前人研究成果的基础上,依据冈底斯中部地区近期地质勘查成果,运用成矿系列理论,以区域构造-岩浆时空演化特征为主导,探讨了区域成矿规律及成矿潜力,在冈底斯中部初步建立了燕山期与花岗质岩石有关的铜—铁—铅锌—银矿床成矿系列和喜马拉雅期与中酸性花岗质岩石有关的铜—铁—铅锌—金矿床成矿系列等2个矿床成矿系列和6个成矿亚系列;划分了洞错—尼玛锑铜多金属矿带、江马—文部铁铜多金属矿带、达雄—甲谷铜铁多金属矿带、隆格尔—尼雄—措麦铁铜矿带和杰萨错—查孜铜、铀钍多金属矿带等5条铁铜多金属成矿带和22个成矿远景区,指明了找矿方向.     

Geological characteristics,metallogenic regularity,and research progress of lithium deposits in China

China is rich in abundant lithium resources characterized by considerable reserves and a concentrated distribution of metallogenic zones or belts, with proven reserves of 4046.8×10³ t (calculated based on Li₂O) by 2021. China is also a big consumer of lithium. By 2019, China ’s lithium consumption in the battery sector alone had reached 99×10³ t, with an average annual growth rate of nearly 26%. China has become the world ’s largest importer of lithium resources, showing a severely unbalanced relationship between supply and demand for lithium resources. Therefore, there is an urgent need for the prospecting, exploitation, and study of lithium resources in China. This study collected, organized, and summarized the data on the major lithium deposits in China, analyzed and compared the spatial-temporal distribution patterns, geological characteristics, and metallogenic regularity of these lithium deposits, and summarized the prospecting and research achievements over the last decade. The major lithium deposits in China are distributed in provinces and regions such as Qinghai, Jiangxi, Sichuan, Tibet, and Xinjiang. These deposits are mostly small in scale. According to different genetic types, this study divided lithium deposits into granitic pegmatite type, granite type, saline lake brine type, underground brine type, and sedimentary type, as well as new types including hot spring type and magmatic-hydrothermal type, and summarized the characteristics and key metallogenic factors of these different types of deposits. Sixteen metallogenic prospect areas of lithium deposits were delineated according to the deposit types and the distribution patterns of metallogenic belts. The paper introduced the research progress in major metallogenic models and lithium extraction techniques made over the past decade. Based on the comprehensive analysis of the prospecting potential of lithium deposits, the authors concluded that the future prospecting of lithium resources in China should focus on lithium metallogenic belts, the deep and peripheral areas of currently determined large-scale pegmatite-type lithium deposits, geophysical-geochemical anomalous areas with mineralization clues, and areas with developed large-scale low-grade associated granite-type and sedimentary lithium resources. The study aims to serve as a guide for the future prospecting of lithium deposits in China.©2022 China Geology Editorial Office.
