| 摘 要： | Sedimentary mineral deposits were not formed simply as product of simplereactions through a single kind of factors,but were outputs of intricate reactionsamong a complex set of evolutionary natural environmental agents.They were formedat least through three different stages,viz.,the imbibition and concentration ofore forming materials;the geochemical enrichment;and the physical concentrationstages(Fig.1).As to industrial phosphorites,physical enrichmnt is of paramountimportance.It seems,almost all of the world industrial phosphorite deposits wereformed as such.Our idea of physical enrichment was first set up in 1980,during the 2ndNational Symposium on Mineral Deposits at Hongchow.Since then,lots of newevidences had been added up.In this paper,only those of phosphorite deposits are described.
