摘　　要：京希金矿床位于博罗科努早古生代岛弧西段吐拉苏断陷中.赋矿地层为下石炭统大哈拉军山组的第二岩性段,含矿岩石主要为硅化火山角砾岩和硅化砂砾岩.矿床处于近NS向与NW向断裂的交汇锐角部位.强烈的硅化、黄铁矿化、毒砂化蚀变组合是高品位矿石的蚀变标志,近矿围岩中高岭石化、绢云母化普遍发育.岩石中富含Au、As、Sb、Hg,贫Cu、Pb、Zn等微量元素.成矿温度130~240 ℃,成矿深度0.67~0.70 km,属浅成低温热液型金矿.The jingxi gold mine bed locate boluokenu early an island of ammonite of the tulasu volcano in.Endow with the mineral geologic strata for descend the anthracites tong dahala junshan set the second rock segment,mainly contain the mineral rock to turn the volcano cape rock and to turn the gravel rock. The mineral bed is placed in the near south north to with north west to split of hand over and remit acute acute angle part.Mightiness of silicon turn the yellow iron mine turn,the poisonous sand turn the eclipse changes the combination is the high personal status mineral stone of eclipse change the marking,the near mineral round the high in rock petrochemical,thinmica of turn the widespread growth,It enrick to contain the little chemical element of au、as、sb、hg、but poverth Cu、Pb、Zn etc.Little chemical element.Become the mineral temperature 130~240℃,become the mine depth 0.67~0.70 km,is shllowto the hot liquidtype of lowtemperoture.
