小秦岭金渠金矿区S202脉组深部成矿规律研讨

Discussion on the metallogenic regularity of the deep vein of the S202 formation in the Qinling Mountains gold deposit area of the small gold deposit

金渠金矿区位于老鸦岔复式背斜东部北翼及西阴-雷家坡向斜东部的两翼,矿区东西各有两大花岗岩体,分别为娘娘山岩体与文峪岩体,区内含矿剪切带发育,成矿成因复杂。矿区在老鸦岔复式背斜内产出的盲矿体位于受韧-脆性剪切带中,通过剪切带的正向剪切和逆向挤压,石英脉在剪切带的有利部位形成矿体。通过对S202矿组研究,得出S202大型剪切带呈鞍状特点,并提出找矿方向。

Jinqu Gold Deposit is located in the laoyacha Anticline of eastern North and West Wing - Yin Lei Jia Po East syncline wings, mine and things have two granite, rock and rock were Wenyu Niangniangshan, development zone containing ore metallogenic complex shear zone. Blind ore mine in laoyacha anticline output in the ductile brittle shear zone, the positive shear shear zone and reverse extrusion, favorable position of quartz veins in shear band formation of orebody. Based on the study of S202 ore group, it is concluded that the S202 shear zone is saddle shaped, and the prospecting direction is proposed.
