| 摘 要： | 经过野外和室内工作,作者提出,西南秦岭与西南贵州都是铀-金-汞-锑-砷(主要是雄黄雌黄,有时毒砂也重要)-铊成矿带。铀矿床的存在使这两个成矿带似乎区别于卡林成矿带,但实际上三者大同小异。本文概略讨论西南秦岭与西南贵州成矿带铀矿床与金矿床的地质背景、矿物组合、微量元素与同位素化学及成矿机制并与卡林型金矿床对比。

| Abstract: | On the basis of field and laboratory studies, the author proposes that both SW Qinlingand SW Guizhou are U-Au-Hg-Sb-As (realgar,orpiment)-Tl metallogenic belts. The findingof U deposits makes these two belts look different from the Carlin-trend deposits,USA, whichare otherwise very similar to the above-mentioned Chinese metallogenic belts. Generalizedgeologic setting, mineral paragenesis, trace element and isotope geochemistry mechanism ofore formation of the U deposits and Au deposits in these metallogenic belts are discussed inthis paper, together with the comparison with the Carlin-type deposits. |
