摘　　要：从物理化学条件中反映研究区内锑矿成矿物质主要来源于重熔型岩浆岩,次为地层本身锑元素;成矿热液沿构造裂隙在多期构造作用下向上运移,并经历碱性-酸性-碱性演化、古水热循环萃取作用,在隆起带中部、边部以及拗陷盆地中的次级隆起区富集成矿。According to the physico-chemical conditions,it is known that the antimony mineralization material in the study area are mainly derived from the remelting magmatic rocks,and are secondarily from the antimony elements of the strata.The hydrothermal fluid migrated upward along the structural faults under the multistage tectonic progress.In the evolution of Alkaline-acid-alkaline,for the extraction function of paleohydrothermal cycle,enrichment and mineralization were developed in the middle and edge of uplift zone,and secondary uplift zone of the depression basin.
