摘要
黔东松桃地区位于慈利-保靖断裂与鹤峰-龙山断裂的夹持区域内。区内褶皱与断裂十分发育,主要发育有NNE-SSW向断裂、线状褶皱,NE-SW向断裂、褶皱以及NW-SE向小型断裂、短轴褶皱。本文对区内主要大型断裂特征及其与汞铅锌金银等热液矿产成矿关系进行了探讨研究,结果表明区内大型断裂多为热液矿产的导矿通道,矿(化)体多产出在这些大型断裂的旁侧次级断裂裂隙中,同时对区内形成于南华纪早期的锰矿体的后期保存与破坏有重要影响作用。
The Songtao dense area of Mn mineral deposits lies between the Cili-Baojing fault and the Hefeng-Longshan fault.Folds and faults are well developed in the area,mainly including NNE-and NE-trending faults and linear folds,and NW-SE trending small faults and short-axis folds.This paper has a discussion on main major faults and their relationship with hydrothermal minerals such as the lead-zinc,gold,silver and mercury mineralization.These major faults acted as ore-bearing hydrothermal channel,and their subsidiary fractures were host structure.Early Mn deposits were destroyed by the major faults.
