摘要
产于晚古生代火山岩中的浅成低温热液型金矿床是新疆北部近期发现的一个重要的金成矿类型。通过对本区部分浅成低温热液型金矿的容矿火山岩岩石化学成分、REE分布模式、硫同位素、氢同位素、氧同位素和锶同位素及流体包裹体成分的分析与对比．讨论了其基本成矿地球化学特征，并揭示了本区浅成低温热液型金矿床与我国东部地区某些产于中生代陆相火山岩中的同类型金矿床在成矿地球化学特征上存在的一些差异。
Epithermal gold depeits formed in Late Paleozoic volcanic formations are considered as an importantmineralizing type newly found in northem Xinjiang. By analyzing and comparing the chemical compositionsof host volcanic rocks, REE patterns, sulfur, hydrogen and, oxygen and strontium isotopic compositions ofore, and fluid indusion compositions with those of some epithermal gold deposits in northern Xinjiang, theauthors discuss their preliminary metallogeno-geochemical characteristics and point out some differences inmetallogeno-geochemical characterist ics between epithermal gold deposits in northern Xinjiang and those ineastern China, which were formed in Mesozoic terrestrial volcanic formations.
