| 摘 要： | 陕西秦巴区元古宙和早古生代火山活动强烈,火山岩发育。经研究,其火山岩形成机制,多与裂谷构造有关。这些火山岩中与之相关的矿产有钼、铼、钨、金、铅、银、锌、铜、铁、金红石及有关的非金属矿等。本文从该区火山岩的特征出发,分析其所产出的大地构造环境,并探讨火山岩与矿产之间的关系,最后提出进一步找矿的建议。

| Abstract: | During the Proterozoic and the Early Paleozoic eras,volcanic activities were strong and volcanic rocks developed well in the Qinling-Dabashan area of Shaanxi Province.The formation mechanisms of those volcanic rocks were mostly related with rift structures and the minerals of molybdenum, rhenium,tungsten,gold,silver,zinc,copper,iron,rutile and some non- metallic ores are relative to the volcanic rocks. Studying the characteristics of the volcanic rocks in this area,the writer has made a detailed analysis on the tectonic environment of the vol- canic rock occurrences and discussed the relationships between the volcanic rocks and mineral resources,thus making suggestions for further ore prosp- ecting. |
