An integrated study of apatites from Haizhou type phosphorite deposits was madein such aspects as their mineral associations, chemical composition,REE analyses,inf-rared absorption spectra,and X-ray diffraction data. The results show that theseapatites were formed by metamorphic transformation-mobilization and migmatized meta-somatic recrystallization, and might be classified into two types:fluorapatite and fran-colite. Unit cell parameters a0=9.3653-9.3819nm,c0=6.8797 - 6.8936nm. Crystallo-chemical formulae (Ca5.00Fe0.02Sr0.01TR0.01)5.04[(P2.99C0.04)3.03O12]F0.08 and(Ca4.94Fe0.02 Mg0.02Sr0.01TR0.01)5.00 [(P2.90Ti0.02Si0.15)3.07)O12]F0.77). These data further demonstrate that the formationof Haizhou type phosphorite deposits is attributed mainly to deposition and metamor-phic transformation and next to migmatization-metasomatism.
