| 中文摘要: |
| 黔北务川—沿河地区是贵州重要的萤石矿产基地，矿床（点）分布密集，显示该地区有较好的萤石（重晶石）找矿潜力。调查显示该区萤石（重晶石）矿的产出明显受北西向节理的控制，并主要赋存在奥陶系桐梓组、红花园组灰岩中，表现为既受北西向节理面的控制、也受湄潭组页岩的明显封盖影响，具有明显的Si/Ca界面控矿的特征。根据界面控矿对该地区萤石矿的控制特征，在隐伏区北西向节理和湄潭组页岩之下，在有利的构造虚脱空间内，是寻找大规模萤石矿床的有利位置。 |
| 英文摘要: |
| Wuchuan-Yanhe area is an important base of fluorite in the northern Guizhou province.In the area the deposits are range and Concentrated and is expected have good exploration potential for the Fluorite（barite）.The distribution of Fluorite（barite） ore was significantly affected by the joint of North West direction，and exist in the Ordovician Tongzi and Honghuayuan formation limestone.Overall display not only affected by the joint plane，is also affected by the Meitan formation shale，which is upper the Honghuayuan formation，obvious seal.Interface control characteristics of the ores is obvious.According to the interface ore controlling of fluorite mine，in the area control features in concealed area north west to joints，under the Meitan formation shale，and in the favorable structural collapse space are looking for potential large-scale fluorite deposit resources. |
