摘　　要：羊拉里农矿段层状块状硫化物矿体下盘产出有蚀变角砾岩筒,在空间上与层状矿体构成"上层下脉",这种组合正是海底喷流-沉积型矿床的一个显著特征。通过岩浆的叠加改造,使早期同生沉积的矿体变富,且带来了大量的伴生元素,钼、金均可达到工业品位,形成伴生矿床。The Yangla copper deposit Linong paragraph mine Altered breccia pipe has outputted footwall layered massive sulphide ore body,up in space with layered orebodies constitute ＂under the upper vein＂,which is the combination of Harbor-sedimentary deposits A significant feature.Through the superposition of magmatic transformation,so that early syngenetic ore deposits become rich,and has brought many associated elements,molybdenum,gold may reach industrial grade,associated with the formation of ore deposits.
