摘要
莒南王家庄子铅锌矿床属于中低温岩浆热液型铅锌矿床,区域断裂构造发育,岩浆多期次活动,成矿地质条件较好。本文从矿体特征、矿石特征、围岩蚀变等3方面,对矿床地质特征进行了阐述,圈定铅锌矿体5个,矿体呈脉状、透镜状,严格受断裂带控制。初步分析、归纳总结矿床成因以及找矿标志,矿体在走向和倾向上均未封闭,具有较大找矿潜力,同时为矿区深部和外围找矿指明了方向。
The Wangjiazhuangzi Pb Zn deposit in Junan belongs to the middle low temperature magmatic hydrothermal Pb Zn deposit with well-developed regional faults,multi-stage magmatic activities and good metallogenic geological conditions.This paper expounds the geological characteristics of the deposit from three aspects of ore body characteristics,ore characteristics and wall rock alteration.Five lead-zinc ore bodies are delineated.The ore bodies are in vein and lenticular shape and are strictly controlled by the fault zone.Based on the preliminary analysis and summary of the genesis and prospecting criteria of the deposit,it is found that the ore body is not closed in strike and dip,and has great prospecting potential,which points out the direction for deep and peripheral prospecting in the mining area.
