本矿区位于宁芜中生代陆相火山岩断陷盆地北段东缘,小丹阳-方山深大断裂西侧,地形平坦,一片浮土覆盖,现已探明是一个中型的铁矿床.矿体产于沿其林山短轴背斜轴部侵入的闪长玢岩和黄马青组砂页岩的接触带中,控制埋深在50到550米之间.矿石类型有磁铁矿、赤铁矿和假象赤铁矿三种,并以后者为主.区内构造比较复杂,北北东向迭瓦式逆断层和近东西向正断层复合在一起.鉴于上述地质原因,本区重磁异常
The mine is located in the eastern edge of the northern section of the Mesozoic continental volcanic faulted basin of the Mesozoic in Ningwu, west of the Danyang-Fangshan deep fault with a flat topography and covered with floating earth and has been proved to be a medium-sized iron ore deposit. In the contact zone of diorite and Huangmaqing formation sand shale intruded along the axis of Linshan stub shaft, the burial depth is between 50 and 550 meters. The types of ore are magnetite, hematite And the illusion of hematite three, and the latter dominated.The structure is more complicated in the region, the North-East and East-East Diego fault reverse fault is combined with the normal fault.Because of the above geological reasons, the area gravity and magnetic anomalies
