摘　　要：通过归纳黔西北地区的区域地质背景,典型矿床的地质特征,比较矿床中矿石和含矿地层的Pb/Zn比值和REE配分模式,分析构造展布、矿床(点)的分布和物探异常之间的关系,提出构造是区域的主要控矿因素,从而强调研究构造体系是综合找矿工作的重点。This paper describes the regional geological background and geological characteristics of typical Pb-Zn deposits in northwestem Guizhou. This study also compares the REE distribution patterns and Pb/Zn ratios of deposits with those of ore-hosted beds, analyzes the distribution relations among the deposits, development of factures and fold structures and geophysical anomalies. Considering that geological structure is a principal factor controlling metallogeny, the authors emphasize that research on structural system is very important for comprehensive ore prospecting.
