| 摘 要： | 八卦庙特大型金矿床是近年发现的产于秦岭地区泥盆系浅变质细碎屑岩中规模最大的微细浸染型金矿，金矿化与石英脉关系非常密切，经过大量分析数据统计表明，金矿石品位与其石英脉带的发育规模、脉体内外硫化物的含量成正比，与脉体的规整程度成反比；与脉体的厚度具有一定的关系。一般说，产于节理中的石英细脉的含金量比顺层产出的石英大脉的含金量高；石英脉的含金量高于脉旁围岩的含金量数倍甚至几十倍，含金石英脉与脉旁蚀变岩石共同构成工业矿体。石英脉带是宏观上直观的找矿评价标志。

RESTUDYING ON THE RELATIONSHIP BETWEEN QUARTZ VEIN AND GOLD MINERALIZATION IN BAGUAMIAO GOLD DEPOSIT |
| |
| Abstract: | Baguamiao giant gold deposit was discovered in 1989.It is the largest micro fine grain disseminated one located in low grade metamorphic fine clastic rock of Devonian system in Qinling area.The gold mineralization is closely related to the quartz vein and to vein thickness to certain degree.According to a lot of analysis data,the gold ore grade is in direct proportion to the development of the vein zone and to the content of sulphide inside and outside the vein,and is inverse to the regulation degree of the vein.In general,the gold content of the vein in joint is higher than that along bedding.The gold content is mostly as several to several tens of times as the content in surrounding rock.Gold bearing vein and alterated wall rock both consist of industrical orebodies.Quartz vein zone is audio visual indicator and estimated marking in macroscopic scale. |
