| 摘 要： | 崖湾金矿床定位于礼县—白云—山阳深大断裂西端的分支断裂罗坝—礼县断裂中段,是李坝大型金矿床的外围矿床之一。通过对矿区水系沉积物、岩石微量元素特征的总结,结合地质因素,指出矿床的主要微量元素为As、Bi、Sb、Ag、Hg。与Au矿关系密切的伴生元素依次为Sb、As、Ag、Hg、Bi。矿床微量元素具有垂直分带性,从上至下的序列为:Ag—Mo—Hg—Pb—Bi—Sb—Au—As—Zn—Cu。对矿体标高和微量元素垂直分带性的研究后认为矿床总体剥蚀程度为上部,矿床向西、向东发展潜力巨大。

| Abstract: | Yawan gold deposit is in the middle section of Luoba-Lixian fault which is a west branch of Lixian-Baiyun-Shanyang great faults, it is one of peripheral deposits around Liba big scale gold deposit. By the summarization of the stream sediment and rock microelement characteristics of deposit area, it is pointed out that the main microelements of the deposit are As, Bi, Sb, Ag, Hg, the accompanying elements which are close relation to gold deposit are Sb, As, Ag, Hg, Bi. The microelements of deposit are vertical zoning which sequence is Ag-Mo-Hg-Pb-Bi-Sb-Au-As-Zn-Cu from top to deep. By studying location of ore body and microelement vertical zonality, it is deemed that overall denudation degree of deposit is in upper, and potential to extend to west and east is high. |
