摘　　要：在松桃举贤锰矿、寨英锰矿地质工作的基础上,通过对松桃举贤地区南华系两界河组、大塘坡组第一段(含锰岩系)分布特征、岩性及厚度变化规律的系统分析研究,类比普觉(西溪堡)地堑盆地特征,发现在南华纪大塘坡早期,位于南华裂谷盆地(Ⅰ级)、武陵次级裂谷盆地(Ⅱ级)、石阡-松桃-古丈地堑盆地(Ⅲ级)中的举贤地区存在一个隐伏的Ⅳ级地堑盆地,仅盆地的北西边缘局部出露地表,大部分隐伏于地下。预测该盆地展布方向为北东东70°左右,长15 km左右,宽3~5 km,锰矿资源潜力大,是寻找隐伏大型、超大型锰矿床最有利的地区之一。目前通过首批深部钻探工程验证,已初步证实这一预测。Based on the geological work of Juxian manganese deposit in Songtao and Zhaiying manganese deposit, the distribution characteristics, lithology and thickness change rule of Liangjiehe formation and the first member of Datangpo formation(manganese-bearing rock series)of Nanhua System in Juxian area of Songtao were analyzed.The systematic analysis and study of the law, analogous to the characteristics of the Pujue(Xixibao)graben basin, was found in the early Nanhua period Datangpo, located in the Nanhua Rift Basin(Class I),the Wuling Secondary Rift Basin(Class II),Songtao ~ In the Juxian area of the Guzhang graben basin(grade III),there is a hidden grade IV graben basin, only the northwest edge of the basin is partially exposed to the surface, and most of it is hidden underground.It is predicted that the distribution direction of the basin is about 70° northeast, about 15km long and 3-5km wide.It has great potential for manganese ore resources and is one of the most favorable areas for finding hidden large and super-large manganese deposits.This prediction has been preliminarily confirmed through the first batch of deep drilling engineering verification.
