引言长江下游南京-芜湖(宁芜)和庐江-枞阳(庐枞)两个中生代晚期火山岩盆地中的铁矿,经过近年来各部门的地质队伍、科研单位及院校的详细工作,基本上查明了矿床的赋有状态、蚀变特征、矿石特点和成矿的主要控制因素,并在宁芜地区根据各种类型铁矿床之间的成因联系,建立了“玢岩铁矿”模式。虽然对“玢岩模式”的名称还有不同意
Introduction The iron mines in the late Mesozoic volcanic basins of Nanjing-Wuhu (Ningwu) and Lujiang-Zongyang (Luzong) in the lower reaches of the Yangtze River have been subjected to the detailed work of geological teams, research institutes and institutions in various departments in recent years. Basically The conferment status, alteration characteristics, ore characteristics and main controlling factors of mineralization have been identified. According to the genetic relationship between various types of iron deposits in Ningwu area, a “rock iron ore” model has been established. Although the name of “rock model” still do not agree
