摘要
晚泥盆世半封闭的湘东海湾中,由古半岛剥蚀、搬运来的铁质,在海岸平缓的滨—浅海相中得以聚集;又受后生作用影响,形成宁乡式铁矿床。华夏系同期背斜构造隆起区是寻找古浅—滨海盆地的前提,其中的凹陷构造是找盲矿体的有利部位。
Iron substance denuned from palaeo-penisular and migrated to the late Devonian semi-closed Xiang-dong bay was accumulated in off-hore and shallow sea facies along the gently dipping sea coast andformed the Ningxiang type iron deposits dy epigenetic metallization.The upwarped district of the Ca-thysian anticlinal structure is the prerequisite for finding Palaeo shallowsea-offshore basin and the do-wnwarpod structure in the basin is the favourable position for hunting concealed deposits of the typehere studied.
