鄂东地区大冶式铁矿是我国重要的铁矿类型之一。关于它的成因,先后提出过矽卡岩型、高温热液型、闪长岩钠化蚀变和膏盐层促进成矿、三叠纪沉积菱铁矿被改造成矿、矿浆成矿等不同看法。目前对这一问题仍有较大分岐。矿床成因研究不仅能够发展成矿理论,更具有指导找矿的实际意义。现以四年来在铁山、鄂城、灵乡和金山店等四个岩体的主要矿床中所进行的研究工作为依据,重点对岩浆活动和铁矿的多期性、矿浆成矿特点以及成矿模式等问题进行探讨。
Daye iron ore in eastern Hubei Province is one of the important iron ore types in China. As for its origin, skarn-type, high-temperature hydrothermal type, sodium diorite alteration and gypsum salt formation have been proposed to promote mineralization. Triassic sedimentary siderite has been transformed into ore and ore-forming, etc. view. At present, there is still a big difference on this issue. The study of deposit genesis not only can develop mineralization theory, but also has the practical significance of guiding mineral prospecting. Based on the research conducted in the four major ore deposits of four rock masses in Tieshan, Echeng, Lingxiang and Jinshandian over the past four years, the author focuses on the magmatic activity and the multi-period of iron ore, the ore-forming characteristics and Mineralization patterns and other issues to be explored.
