摘　　要：桂西北丹池成矿带是我国南方一条重要的锡多金属成矿带,由芒场、大厂和五圩等3个主要矿田组成。作者通过系统的构造调查,将带内控矿构造样式归纳为上脉下层、以脉状矿为主的"马鞍山式";上脉下层、以层状矿为主的"铜坑式"和以脉状矿为主的"箭猪坡式"。总结了不同构造样式的产出地质背景和构造特征。在此基础上,提出了芒场矿田马鞍山铅锌矿和五圩矿田箭猪坡铅锌矿的找矿方向。The Nandan-Hechi metallogenic belt, consisting of Mangchang, Dachang and Wuxu ore fields,is an important tin-polymetallic metallogenic belt in South China. Based on detailed field investigations ,the ore-controlling styles of this belt can be classified into as follows ：, （ 1 ） ＂ Maanshan style＂, typical ore-controlling structure in the Mangchang ore field,with veins in the upper portion and strata in the lower portion, dominated by vein-like orebod- ies;（2） ＂Tongkeng style＂, typical ore-controlling structure in the Dachang ore field, also with veins in the upper portion and strata in the lower portion, but dominated by layered orebodies ; （3）＂ Jianzhupo style＂, typical ore-controlling structure in the Wuxu ore field, dominated by vein-like orebodies. Moreover, the geological setting and structure characteristics of different ore-controlling styles are discussed. According to these ore-controlling styles, it is suggested that some places,such as the northwestern Maanshan Pb-Zn ore deposit in the Mangchang ore field,and the east and south of the Jianzhupo Pb -Zn ore deposit in the Wuxu ore deposit,are probably the loci of concealed orebodies.
