摘要
小栗子银及多金属矿处于老岭复式背斜南东翼与鸭绿江深断裂交汇处的断裂中,且处于火山活动频繁部位,即在望江楼组陆相沉积地层与燕山期超浅成火山岩-安山岩与浅成侵入岩-花岗闪长斑岩交互带中。断裂构造十分发育,为岩浆热液活动提供了通道和储存空间,该矿床的成因属受火山机构控制的火山期后中—低温热液充填交代矿床。
Xiaolizi silver and polymetallic ore lie in the fracture at the junction between southeast limb of the Laoling anticlinorium and the Yalu River deep fault, and in the volcanic activity part, that is in interactive belt between Wangjianglou Group continental sedimentary strata and the Yanshanian ultra hypabyssal volcanic rock-andesite and hypabyssal intrusive rocks-granodiorite porphyry. Faults are well developed, which providing channel and storage space for magmatic hydrothermal activity. The genesis of the deposit is post volcanic middle-low temperature hydrothermal iflling-metasomatic deposit controlled by volcanic apparatus.
