北山地区铅锌矿成矿类型及找矿方向

Metallogenetic Types of Lead-Zinc Deposit and Prospecting Direction in Beishan Area

概述北山地区铅锌矿的分布特征,根据主导成矿作用分类,北山地区主要是与钙碱性岩浆岩建造有关的铅锌矿成矿系列。通过对花牛山铅锌银多金属矿和白山堂铜锌矿床两个典型矿床的剖析,分析其成因和分布规律,提出找矿标志以及北山地区铅锌矿有利的成矿靶区。

Beishan area, where distribution characteristics of lead-zinc deposit is briefly introduced in the paper firstly. According to classification of principal metallogenic process, it is mainly lead and zinc deposit metallogenic series which relates to calcium-alkaline magmatic rock formation. Secondly, through the study on two typical deposits as lead-zinc-silver polymetallic deposit of Huaniushan and copper-zinc deposit of Baishantang, its genesis and distribution regularity are analyzed. Finally, the authors propose the prospecting criteria and favorable metallogenic target of lead-zinc mine in Beisban area.
