摘　　要：本文研究了符竹溪金－锑矿床微量元素地球化学特征，对矿区岩、矿石微量元素进行了相关分析，筛选出对符竹溪地区金、锑矿有指示意义的Ａｕ，Ｓｂ，Ａｓ，Ｍｏ，Ｗ，Ｈｇ，Ｐｂ，Ａｇ，Ｔｌ，Ｂｉ等１０个指示元素。经分析对比，确定其实用性指示元素为Ａｕ，Ｓｂ，Ａｓ，Ｍｏ，Ｂｉ，Ｈｇ。利用这些元素的轴向分带规律及比值指标对该矿床深部进行了成矿预测，并已由探矿工程证实，见到了金品位高达４４×１０（－６）的矿体，因而扭转了该矿山矿石资源面临枯竭的局面，经济效益显著。同时，对整个符竹溪地区，即矿床边部及外围作了化探选区，选出了３个远景地段：矿床南部竹叶山地段、外围杨家冲地段和田庄湾地段。In this paper geochemical features of microelements of Fuzhuxi gold-antimony deposit are studied,and correlation analyses have been done on microelements in rocks and ores of the deposit. So the ten indicator elements of gold and antimony in Fuzhuxi area are selected and determined, which include An, Sb, As, Mo, W, Hg, Pb, Ag, T1 and Bi. By analyses and comparison, An, Sb, As, Mo, Hg and Bi are determined as practical indicator elements for gold-antimony prospecting in this area. Metallogenic prognosis for the deeper part of the deposit are conducted by using elements' axial zonality and their ratio index,which are demonstrated by exploration engineering, ore bodies of gold grade up to 44 × 10-6 being found.Therefore,the tense situation about An and/or Sb ore resources was eased up in the mine,and economic benefit became remarkable. Moreover,three prospective sectors are selected in the area (the part near the deposit and its periphery) by geochemical exploration,which are Zhuyeshan sector south of deposit,Yangjiachong and Tianzhuangwan sectors in the periphery.
