Studies show that the average ratio of w/w(P2O5)(1.62) of phosphates in submarine guyots is the same as that of w/w(P2O5)（1.621）of carbonate-fluorapatite, but is obviously different from that of w/w(P2O5)（1.318）of fluorine_carbonate, suggesting that the phosphates from northwestern Pacific are species of carbonate_fluorapatite.Three types of microneedle-microcolumnar, microgranular and microcryptocrystalline carbonate_fluorapatite with different abundances have been found.

The crystal constant of α has a range from 0.932 nm to 0.933 nm with an average of 0.933 nm. Various replacement and remnant structures show that the phosphorates in submarine guyots are mainly of replacement origin.
