| 摘 要： | 通过对大兴安岭古利库金银矿床的成矿热液流体的温度测定和同位素组成的研究,确定该矿床属浅成低温热液类型,并将成矿作用划分为2个成矿阶段,早期阶段成矿温度240~280℃,晚期成矿温度185~235℃.成矿热液流体的氢氧同位素组:δDH2O-76‰~-94‰,δ18O-6.58‰~-14.11‰,表明成矿热液来自大气降水.矿石的硫和铅同位素组成说明成矿热液硫来自中生代火山岩,而铅是从基底落马湖变质岩系及相伴的兴凯期花岗岩类中萃取出来的.

| Abstract: | Guliku gold( silver) deposit is located at the connection of Dayangshu volcanic basin and Luomahu intermediate uplift. Besed on the stable isotope composition study, a mineralization model for Gulilu Au( Ag) deposit is proposed, i.e.an adular sericite type of epithermal gold( silver)deposit with horizontally zoned Au Ag ore bodies occurring in the limb of a paleo volcanic dome on the margin of a Mesozoic continental volcanic basin.The mineralization is in two stages.The temperature of the early stage is between 240℃ and 280℃ ,while that of the late stage is from 185℃ to 235℃ .The isotopic composition(δ DH2O 76‰ to 94‰ ,δ 18O 6.58‰ to 14.11‰ ) suggests that the minerlizing solution is derived from mainly meteoric water. The S and Pb isotopic study shows that the“ hydrothermal sulfur" is derived from volcanic rocks and the “ hydrothermal lead” is from the basement and associated granitoids. |
