摘　　要：贵州独山锑矿田位于扬子古陆西南缘与雪峰山隆起的嵌接部、黔南坳陷东部独山箱状背斜中,是贵州省锑资源基地,该区成矿地质条件优越,锑找矿潜力巨大。NE向的半巴断裂带控制了区内锑矿床(点)的分布,是本区主要控矿构造。本文以该断裂带为研究对象,总结区域地质特征,通过地物化遥找矿方法研究,集成了该区地质、地球物理、地球化学及遥感等找矿信息,提出该区找矿标志包括地层岩性、断裂构造、围岩蚀变、矿化体(或矿体)的风化露头、地球物理和遥感等。在此基础上,初步建立找矿模式,并提出本区找矿靶区优选的准则,优选出半坡、巴年、贝达3个找矿靶区。The Dushan antimony ore field in Guizhou Province is located in the Dushan boxy anticline within the eastern part of the Southern Guizhou depression in the conjunction of the southwestern Yangtze ancient land and the Xuefeng mountain uplift. It is an antimony resource base in Guizhou Province. There are superior Sb metallogenic geological conditions and great antimony prospecting potential in the area. The NE-trending Banba fault zone is the main ore-controlling structure controlled the distribution of antimony deposits(occurrences) in the area. In this paper, aiming at the Banba fault zone as study object, we have inductived the regional geological characteristics, integrated prospecting informations including geological, geophysical, geochemical, and remote sensing ones of the area based on researches of geological, geophysical, geochemical, remote sensing exploration methods, and proposed prospecting criteria including stratum lithology, fault structure, wallrock alteration, weathered outcrop of mineralized body(or ore body), and parameters of geophysics and remote sensing. Then, we have established a preliminary prospecting model, put forward the criteria for optimizing the ore-prospecting target in this area, and finally have optimally outlined three antimony prospecting targets including the Banpo, Banian, and Beida targets.
