中文摘要:
      南阳山锑矿位于五里川锑成矿亚带,属热液矿床,矿体分布在双槐树断裂带南侧F1、F2断裂带内。本文通过野外观察、薄片分析、微量元素分析等方法,对南阳山矿区地质特征及其矿床成因进行分析。本区矿石可分为三类:角砾状矿石、团块状矿石、充填脉状矿石,其中角砾状矿石为主要矿石类型。矿石矿物有辉锑矿和锑华,其中以辉锑矿为主。南阳山锑矿成矿元素Sb主要来源于秦岭群(赋矿层),S元素随热液来源于深部岩浆。含矿断裂带F1、F2深部与其北侧双槐树大断裂相连,热液沿双槐树断裂带向上运移至断裂分叉部位发生分流,分流热液继续汇集秦岭群内成矿元素,在上升至成矿有利部位便聚集成矿。这对南阳山锑矿盲矿体的寻找具有重要的指导意义,同时对寻找五里川锑成矿亚带内新矿(化)体具有重要的借鉴意义。
英文摘要:
      As a part of the Wulichuan antimony metallogenic belt, the Nanyangshan deposit is a hydrothermal deposit, with ore bodies distributed within faults south of the Shuanghuaishu fault zone. By field observation, microscope image analysis and trace element analysis, this work analyzed geological characteristics and genesis of the Nanyangshan deposit. The ore in this deposit can be divided into three types: brecciated ore, crumby ore, and filling nervation ore, of which the brecciated ore is dominant. The ore mineral can be divided into stibnite and valentinite, and the main ore mineral is stibnite. The stibium of ore-forming elements mainly originated from the rock of the Qin Ling Group and sulfur from the deep magma. These ore-controlling fault zones are connected with the Shuanghuaishu fault zone at depth. The hydrothermal solution migrating along with the Shuanghuaishu fault flowed to these ore-controlling fault zones as bifurcation, and ore-forming elements continued to pool in the Qin Ling Group, and accumulated at favorable localities. This recognition might have significance for the exploration of blind ore bodies in the Nanyangshan deposit, and is also a reference for seeking new ore bodies in the Wulichan antimony metallogenic belt.
