从成矿地质背景、矿区地质特征等入手,分析了铅锌多金属矿的控矿因素,认为成矿受构造及岩浆岩控制,且南部的流纹斑岩体为该区的成矿母岩,近东西向及北西向断裂带为主要的控矿构造。初步认为本区中部和南部的深部具较理想的找矿前景,尤其是南部流纹斑岩体附近,重点要注意近东西向和北西向断裂,以及流纹斑岩与二长花岗岩接触带的找矿工作。
Based on the metallogenic geological background and the geology characteristics of the ore district, the ore-controlling factors of the lead-zinc polymetallic deposit are analyzed. It is considered that the metallogenesis is controlled by the tectonism and magmatic rocks, and the rhyolite porphyry in the south is the metallogenic parent rock , Near east-west and north west fault zone as the main ore-controlling structure. It is preliminarily thought that the prospect of prospecting in the deep in central and southern part of this area is more ideal. Especially in the vicinity of the rhyolite porphyry in the southern area, attention should be paid to the near-EW and NWW faults and the contact zone between rhyolite porphyry and monzonitic granite Prospecting job.
