Consideration on the Deep-iron Ore Deposits Prospecting in the Middle-Lower Yangtze Metallogenic Belt
摘要
Abstract
The Middle-Lower Yangtze metallogenic belt is a intra-continental belt dominated by Yanshannian magmatic mineralization. There are two types of iron ore deposits in this area: one occurs mainly in volcanic-sedimentary basin and is genetically related to the intrusion of intermediate to mafie magma and slightly alkaline magma, the other occurs in uplift area and the transitional zone of uplift and subsidence.Based on the investigation of regional metallogenic background, the iron ore types are subdivided. It pointed out that some problems which affect iron deposit prospecting need to solve. According to the progress in deep-iron deposit prospecting, the focus of this study is to discuss similarities and differences of the iron mineralization in the Ningwu and Luzong volcanic-sedimentary basins, and some issues related to deep-iron ore prospecting. It is suggested that the deep-iron prospecting in this area should concentrate on the floor of the sedimentary basin and transitional zone of the basin and uplift areas. Daye-type Cu-Fe deposit and Tongling-type Fe-Cu and porphyry Cu deposits should be the major prospecting targets for upcoming work.关键词
