鄂东地区大冶式铁矿是我国重要的铁矿类型之一。深入研究其成因,无疑对发展成矿理论和指导找矿有重要意义。关于它的成因,前人先后提出过矽卡岩型（接触交代）、闪长岩钠化蚀变和膏盐层促进成矿、三叠系沉积菱铁矿被改造成矿、矿浆成矿等不同看法。现以四年来对鄂城、金山店、灵乡和王豹山等四个岩体有关矿床研究所获的野外资料为基础,对成矿流体的性质进行初步探讨。
Daye iron ore in eastern Hubei Province is one of the important iron ore types in China. Studying its causes in depth is undoubtedly of great significance for the development of mineralization theories and guidance for prospecting. For its cause, the authors have put forward skarn type (contact account), sodium diorite alteration and gypsum salt layer to promote mineralization, Triassic sedimentary siderite was transformed into ore, ore and other mineralization Different views. Based on the field data obtained from the four ore bodies related to ore bodies such as Echeng, Jinshandian, Lingxiang and Wangbaishan in the past four years, the properties of ore-forming fluids are discussed tentatively.
