摘要
衡东县东岗山矿田内发育着两个完美的对顶帚状构造,它们对东岗山和吊马垄两个锡铅锌矿床的形成和富集具有极其重要的控制作用。本文介绍了它们的发育特征,讨论了形成的边界条件,进行了构造应力场分析。在此基础上,较深入地论述了它们对成矿控制的若干规律,进而具体地指出了深部找矿最有利的部位,值得验证。
Two complete revesed S-type brush structures developed in the Donggangshan orefield, Hengdong county, which shew important control on the enrichment and formation of two tin-lead-zinc deposits in Donggangshan and Diaomalong. Their development are introduced, their boundary condition of formation are discussed, and the tectonic stress field are also analysed in this paper, Based on the above studies, their orecontrolling patterns are further discussed, and the favourte position for orebodies in the deep part are also concretely pointed out, which deserves to be verified.
