| 中文摘要: |
| 贵州省丹寨县老东寨—乌佐铅锌矿床是湘西—黔东铅锌成矿带南段新发现的一中型规模铅锌矿床。通过系统梳理矿床地质特征，发现NNE向和NW向断层、板岩与白云质灰岩的岩性组合是老东寨-乌佐铅锌矿床的重要控矿因素；硅化、黄铁矿化、重晶石化与方解石化的热液蚀变组合，以及铅、锌、镉化探异常是区内直接找矿标志。通过综合对比分析，初步认为老东寨—乌佐铅锌矿床属于MVT型铅锌矿床。老东寨Ⅲ号矿体为国内首次在陡山沱组中发现的单矿体达中型规模的MVT型铅锌矿体，拓宽了国内MVT型铅锌矿找矿勘查范围。 |
| 英文摘要: |
| The Laodongzhai-Wuzuo Pb-Zn deposit in Danzhai， Guizhou Province is a newly discovered medium-sized Pb-Zn deposit in the southern Xiangxi-Qiandong Pb-Zn metallogenic belt. Based on a systematical Summary of the geological characteristics， it is concluded that the NNE- and NW-trending faults， as well as the lithologic combination of slate and dolomitic limestone are important ore-controlling factors of the Laodongzhai-Wuzuo Pb-Zn deposit. Hydrothermal alteration of silicification， pyritization， baratization and calcitization， and geochemical anomalies of Pb， Zn and Cd are direct prospecting criteria in the area. Through comprehensive comparison， it is believed that Laodongzhai-Wuzuo Pb-Zn deposit belongs to MVT type Pb-Zn deposit. The Laodongzhai-III ore body is a medium-sized type MVT type Pb-Zn deposit that first discovered in Doushantuo Formation， which broadens the direction and scope of prospecting for MVT type Pb-Zn deposit in China. |
