R型聚类分析可以揭示岩体与岩体、期次与期次之间可能存在的内在联系(郑济林,1987)。宁芜地区位于长江中下游多金属成矿带,盆地内发育有一系列与白垩纪陆相火山岩-次火山岩有关的铁矿床(Mao et al.,2011)。宁芜研究项目编写小组(1978)根据矿床与辉长闪长岩的成因联系以及矿床本身的次火山成因特点,提出了“玢岩铁矿”的成矿模式,认为长江中下游宁芜、庐枞盆地中铁矿床的形
R-cluster analysis can reveal the possible relationship between rock mass and rock mass, period and period (Zheng JL, 1987). The Ningwu area is located in the polymetallic metallogenic belt in the middle and lower reaches of the Yangtze River. There are a series of iron deposits associated with the Cretaceous continental volcanic-subvolcanic rocks in the basin (Mao et al., 2011). According to the genetic association between the deposit and the gabbro-diorite and the genesis of the secondary volcano in the deposit itself, the authoring team of the Ningwu Research Project (1978) put forward the metallogenic model of the “iron rock”, saying that Ningwu in the middle and lower reaches of the Yangtze River , Luzong basin shape of iron ore deposits
