本文分析了某银铅锌多金属矿地质特征及成因分析,并阐述了银、铅、锌的成矿规律。矿体严格受断裂构造和花岗岩体控制,燕山期深部岩浆为成矿提供成矿物质,北西向断裂构造为成矿提供运移通道和容矿空间。得出该矿床为构造—岩浆热液作用中低温热液脉状硫化物矿床。
This paper analyzes the geological characteristics of a silver-lead-zinc polymetallic deposit and its genesis, and expounds the metallogenic regularity of silver, lead and zinc. The ore body is strictly controlled by the fault structure and the granite body. The deep magma in the Yanshanian period provides ore-forming materials for metallogenesis and the NW-trending fault structure provides migration channels and ore-hosting space for metallogenesis. It is concluded that this deposit is a mid-low temperature hydrothermal vein-like sulfide deposit with tectono-magmatic hydrothermal activity.
