贵州省青杠林铅锌矿床主构造特征及找矿远景浅析

Major Tectonic Characteristics and Prospecting Potential for the Qingganglin Pb-Zn Deposit,Guizhou

根据矿区内大比例尺地质测量及主构造微量元素分析结果,对矿区内主构造特征、含矿性以及矿床的成矿规律、控矿因素进行了解析。青杠林铅锌矿床铅锌元素在多期构造活动时,随热液通道向上迁移,并在导矿构造两侧的层间破碎带、韧性剪切带内富集成矿。矿床成因类型属中低温热液充填交代型铅锌矿床。本文结合区域铅锌矿成矿规律及成矿条件对青杠林铅锌矿床的找矿远景作出了初步的评价。

This paper deals with major structures and their ore-bearing potential,ore control factors and ore-forming regularity in the Qingganglin Pb-Zn deposit based on large scale geological survey and contents of minor elements in the major structures.Pb and Zn were deposited in interlayer fractured zone and ductile shearing zone by passage way for ore fluids,forming meso-and epithermal filling-metasomatic deposit.The prospecting potential is assessed.
