摘要:
杨家庄金多金属矿床位于北秦岭2个区域构造之间的金多金属韧性剪切成矿带上，目前已圈出12条金多金属矿体，均呈似层状、脉状、透镜状产于断裂蚀变带中。综合分析表明：矿体受地层、构造及岩浆岩多重控制，二郎坪群大庙组变质凝灰岩及碳质板岩为赋矿围岩，北西西向断裂为主要控矿构造，燕山期第二期花岗岩为矿质的活化、迁移、富集提供了热源。

Abstract:
The Yangjiazhuang Gold Polymetallic Deposit is located in the gold polymetallic ductile shear metallogenic belt between the two regional structures of the North Qinling Mountains.For now,12 gold polymetallic ore bodies have been delineated.They are stratiform,veins and lens occurring in fractured alteration zones.Comprehensive analysis shows that ore bodies are controlled by multiple factors such as strata,structures and magmatic rocks.The host rocks are metamorphic tuff and carbonaceous slate of the Erlangping Group Damiao Formation.The NWW-trending faults are the main orehosting structures.The secondphase granite of Yanshanian period provided the heat source for the ore-forming minerals activation,migration and enrichment.
