| 中文摘要: |
| 砂宝斯金矿床产于中侏罗统陆相碎屑岩中,共有6条矿脉,走向近SN向,矿床的形成经历了4个成矿期、6个成矿阶段,矿石类型主要为蚀变砂岩型和构造破碎蚀变岩型,SN向断裂为主要控矿构造,成矿溶液是岩浆热液和大气降水的混合流体,矿床是在成矿流体处于中低温、低盐度、低压浅成、偏碱性、高硫低氧、相对还原环境的物理化学条件下形成的,属中低温蚀变砂岩型。区域构造和水系沉积物测量是区内有效的找矿方法。 |
| 英文摘要: |
| Shabaosi gold deposit occurs in the terrestrial clastic rocks of Middle Jurassic Series including 6 ore veins trending roughly in N-S diection.It was formed in 4 metallogenic epochs and 6 stages.There are two types of gold ore,i.e.the altered sandstone type and the altered cataclastic rock type.The N-S fracture is the main ore-control structure and the ore fluid is the mixed liquid of magmatic hydrothermal fluid and meteoric water.The deposit was formed under condition of medium-low temperature,low salinity,low pressure,high sulfidation and low oxidation,sub-alkali and relatively reduced environment at shallow depth.It is a medium-low temperature sandstone type gold deposit.Regional structural and river sediment surveys are effective to the ore prospect. |
