| 中文摘要:西藏特提斯喜马拉雅成矿地质条件优越，是中国重要的锑矿成矿带之一，但矿产地质调查工作程度较低。文章在总结西藏特提斯喜马拉雅锑矿成矿地质条件的基础上，系统整理区域地球化学勘查数据，查明锑地球化学异常分布特征，优选找矿远景区。研究结果显示，西藏特提斯喜马拉雅锑矿主要受东西向和南北向断裂控制，基性岩脉可能是矿床重要的成矿物质来源之一。西藏特提斯喜马拉雅锑地球化学异常具有“东强西弱”的分布特征，异常多呈不规则面状或长透镜状沿区域构造线展布，并伴有Au、Ag、As、Hg等元素异常，指示构造对异常分布的强控制性。文章以此为基础，结合伴生元素组合和锑矿资源分布特征，在西藏特提斯喜马拉雅圈定Ⅰ类找矿远景区2处、Ⅱ类找矿远景区1处、Ⅲ类找矿远景区4处。研究结果对西藏新一轮找矿突破战略行动工作部署具有一定参考意义。 |

| Abstract:The Tethyan Himalaya in Xizang exhibits highly favorable metallogenic geological conditions, ranking as one of the key Sb mineralization belts in China. However, the mineral geological survey work in the Tethyan Himalaya remains at a relatively low level of detail and coverage. By synthesizing the metallogenic geological controls of Sb deposits in the Tethyan Himalaya, systematically analyzing regional geochemical exploration datasets, and characterizing the geochemical distribution patterns of Sb, this study aims to identify and prioritize prospective ore-prospecting areas. Results indicate that Sb mineralization in the Tethyan Himalaya is predominantly controlled by east-west and north-south trending fault systems, with basic dikes inferred to be significant sources of metallogenic materials. Sb geochemical anomalies display a distinct “east-strong, west-weak” distribution pattern, occurring primarily as irregular planar or elongated lenticular zones along regional tectonic trends. These anomalies are consistently associated with co-occurring Au, Ag, As, and Hg anomalies, highlighting the critical control of tectonic structures on their spatial distribution. Incorporating the spatial associations of these element assemblages and known Sb resource distributions, this study delineates 2 Class I, 1 Class II, and 4 Class III prospecting potential areas within the Tethyan Himalaya. The research results have a certain reference significance for the deployment of a new round of prospecting breakthrough strategic action in Xizang. |
