| 摘 要： | 通过对长江中下游成矿带成矿地质背景、宁芜与庐枞火山盆地成矿对比等研究基础上,提出该区中生代陆相火山岩盆地及外围地区铁矿具有"双层结构控矿"的认识,上部为玢岩铁矿、下部类似于"大冶式"铁矿;同时,总结了区域铁矿成矿规律,提出了区内铁矿勘查的下步主要方向。

| Abstract: | Based on study of geological setting of metallogenic belt along the mid-lower Yangtze River reach,metallogenic comparison between the Ning-Wu and Lu-Zong basins,it is argued that the iron ore deposit in the Mesozoic terrestrial volcanic basin and its periphery in the area has a ＂double-layer ore-control structure＂that consists of the upper part of porphyry iorn ore and the lower part similar to ＂Daye＂iron ore.Regional iron ore-forming law was summarized and major direction shown for further iron ore exploration in the area. |
