摘要
In this paper, the authors studied the metallotectonic environment, ore-bearing formation and geochemistry of the greenstone belt iron-phosphate deposits in the northern margin of the North China platform. The result shows that the island arc-chlorite is the main native rock, and the post metamorphic host rocks belong to alkali- ferruginous and femic series. By analogy with the present exploitation situation of the low-grade endogenetic iron-phosphorite deposits in north China, there will be a good prospect of comprehensive utilization of greenstone belt iron-phosphate deposits in the northern margin of the north china platform.
