摘　　要：文中介绍了连城锰矿兰桥矿区的地层分布特征,在本区划分出栖霞组地层.讨论了含锰层位和中生代风化环境等区域地质背景.认为本区氧化锰矿床是风化成因.Stratigraphic distribution characteristics of the Lanqiao ore area of the Liancheng manganese mine are described in this paper, from which the Qixia Formation has been recognized. The regional geological setting including the Mn-bearing ore horizons and Mesozoic weathering environment arc also discussed. It is believed that the oxidized Mn-deposits of this district are of weathering type.
