Based on results of nannofossil analysis and 10Be dating in ferrom.nganese crusts m.-1 and A1-1 (no nannofossils were found in it),from.the western and central Pacific respectively,it is found that the crust growth ages from.nannofossil biostrati-graphy agree well with those based on 10Be isotope analysis. Both crusts have three growth layers,and the oldest layer was deposited in m.ocene at about 12.80 m.. The m.xim.m.m.nim.m.and average growth rates of crust A1-1 (from.the central Pacific) are 8.11,1.92 and 3.47 m./m.,and those of crust m.-1 (from.the western Pacific) are 2.93,0.47,and 0.94 m./m..
