摘要
Based on analysis of the metallogenetic models and ore geological settings of both the Ningwu-type and Daye-type iron deposits which are the most important deposit-types in the low-middle Yangtze Fe-Cu-Au polymetallic metallogenic belt,and on the vacant predication theory of metallogenic series,the authors suggest that the magmatic bodies occur as double-layers in the southern Ningwu Basin and that the deep part of the southern Ningwu Basin has ore-forming geological conditions similar to that the “DaYe-type” iron deposit.Therefore,the authors argue that the Daye-type iron deposit can be found beneath the porphyrite-type iron deposit in the southern Ningwu Basin.Furthermore,a "丰"—type metallogenetic model is suggested for the deposits in the southern Ningwu Basin.And thus,the authors suggest that a better prospecting effect may be obtained by synthetical survey using stereoscopic mapping,“model” of analog and integrated geophysical method.
