作者通过对晚震旦世沉积相,以及磷块岩矿床中一些值得注意的现象,海侵方向和磷块岩形成机理,及其分布规律的研究,指出:我国一系列巨大的磷块岩矿床的主要成矿原因,是它们位于我国东部和西部两大主导构造体系相复合地带。两种地球化学性质不同的海流相交汇部位,是我国重要的磷矿成矿带。据此,作者认为:我国内蒙西部额齐纳旗——狼山一带;淮阳山字型前弧及东翼反射弧之南侧,特别是九岭山—天目山隆起带,即原始江南古陆之北、东缘赣北、皖南及浙西一带,可能是希望较大的磷块岩远景区。
The authors pointed out that a series of giant phosphorite deposits in China are based on the late Sinian sedimentary facies, as well as some noteworthy phenomena in the plutonite deposits, the direction of transgression and the formation mechanism of phosphorus rock, and their distribution laws. The main reason for the metallogenesis is that they are located in the composite zone of the two major structural systems in the east and west of China. Two geochemically different marine currents intersect each other and are important phosphate mineralization belts in China. Based on this, the author believes that: in the western part of China’s Inner Mongolian Ejinaqi--Langshan area; the south side of the Huaiyang mountain-shaped front arc and the eastern wing reflex arc, especially the Jiulingshan-Tianmushan uplift zone, namely the primitive Jiangnan ancient land In the north and east of the Yubei, Weinan, and Zhexi areas, it may be the larger prospects for phosphorus rock.
