460铀钼矿是一大型铀钼共生矿床,矿床定位于多组断裂构造与火山机构的复合部位,铀钼矿体赋存于火山通道相次火山岩体和隐爆角砾岩中,以浸染状、网脉状矿化形式为主,围岩为酸性火山岩,矿物组合与蚀变有分带特点,并有高、低温矿物共存现象.火山岩、次火山岩中有较高的铀钍丰度.硫同位素表明成矿物质来源于基底岩石和火山岩围岩;氢氧同位素表明成矿热液主要为大气降水经深部加热形成.矿床类型为与次火山岩有关的热液矿床.

Ore deposit 460 is a large uranium-molybdenum deposit located at the the superimposition of multi-group fractures and volcanic apparatus. Uranium-molybdenum ore bodies occur in the sub-volcanic rock within the volcanic feeder and in the crypto-exploded breccia. Dissemination and stockwork are the main mineralization styles. The host rock is acidic. The ore bodies are characterized by mineral and alteration zoning and co-existing of high and low temperature minerals. S isotopes indicate that the ore materials are derived from the magmatic hydrothermal fluid and dominated by the crustal materials. The ore fluid is mainly meteoric water heated at depth. Genetically, the ore deposit is a hydrothermal deposit related to sub-volcanic rock.
