摘要
790铀金矿田位于西秦岭东北段—北北东向的构造-岩浆活化带上。矿田内的若干个铀、金矿床都集中分布于790产铀岩体的内、外,与成矿关系较密切的700岩体是一个多期多次侵入与喷溢的复式岩体,它产出于东西与南北向两区域性深断裂系相交汇的特定部位。本文通过对矿田内铀、金矿床成矿地质特征的分析类比,论述了铀、金成矿的相似之处,以及矿床分布所显示出明显分带的差异性,从而启示人们,在找铀的有利地区要注意寻找金矿。
U-Au ore field No. 790 is located in a NNE-trending tectono-magmatic reactivated zone in the northeastern section of western (?)inling. Uranium and gold deposits within the ore field are all centralized within or near a uranium-productive massif No. 790. The massif, closely related to metallogenesis, is a composite massif of multi-stage and multi- intrusion and effusion which occurs at the specific intersection part between two regional deep fault systems in EW and NS directions. Through the analysis and comparison of metallogenetic geological characteristics of uranium and gold deposits in the ore field this paper deals with similarity in metallogencsis of uranium and gold, difference in distinet zoning of uranium and gold deposits. It is suggested that attention should be paid to areas considered to be favourable for uranium while prospecting for gold.
