一、地质产状江苏某地金-银碲化物在江苏省首次发现,它们产于含金石英脉中。该地在构造上处于一火山岩断陷盆地的中部。与金-碲矿化有关的地层为侏罗系上统大王山组的粗安质火山碎屑岩和火山熔岩。区内次火山岩发育,主要是粗安玢岩和石英粗安玢岩。围岩蚀变有硅化、绢云母化和黄铁矿化等。局部构造破碎强烈。金-银碲化物产在强烈蚀
First, the geological production Jiangsu gold - silver telluride was first found in Jiangsu Province, they are produced in the quartz vein. The site is structurally located in the middle of a volcanic faulted basin. The strata associated with the gold-tellurium mineralization are the Jurassic Dawangshan Formation, the Jurassic pyroclastic clastic rocks and volcanic lava. The secondary volcanic rocks in the area are mainly coarse andesite and quartz rough andesite. Wall rock alteration silicification, sericitization and pyrite mineralization. Local structure broken strong. Gold - silver telluride production in a strong eclipse
