浅析火山岩型金属矿的成矿地质特征

A Brief Analysis of Metallogenic Geological Characteristics of Volcanic Metal Deposits

赋存于火山岩中的金属矿床为火山岩型金属。其中,火山碎屑岩、火山沉积岩以及火山熔岩中都存在金属矿床,还包括浅变质岩和陆相砂砾岩中的金属矿床。俄罗斯火山岩型金属矿床的种类与数量最多,并且其资源的储备量也是占有较高的位置。

Metal deposits hosted in volcanic rocks are volcanic-type metals.Among them,there are metal deposits in pyroclastic rocks,volcanic sedimentary rocks and volcanic lavas,including metal deposits in epimetamorphic rocks and continental sandy conglomerates.Russian volcanic rock type metal deposits have the most types and quantities,and their reserves also occupy a high position.
