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。
Gossamer Temple is a large gold deposit discovered in recent years in the Qinling Mountains Devonian metamorphic fine metamorphic fine-grained fine-grained gold deposit, gold mineralization and quartz veins very closely, after a large number of statistical data show that, The grade of gold ore is proportional to the developmental scale of quartz veins and the content of sulfides inside and outside the veins, which is inversely proportional to the regularity of the veins and has a certain relationship with the veins thickness. In general, the quartz veinlets produced in the joints have a higher gold content than the quartz veins produced in the bedding; the gold content of the quartz veins is several times or even several times greater than that of the surrounding veins, and the gold-bearing quartz veins and Periplane alteration rock together constitute the industrial ore body. Quartz vein belt is a macroscopic visual indicator of prospecting evaluation.
