Acknowledgements The authors thank Drs. Meng Xianwei, Liu Jihua, Chen Zhihua and Bu Wenrui for helpful discussion in sample analysis and measurements. The preliminary treatment of samples for ^10Be dating was made at ^10Be Laboratory, Guangzhou Institute of Geochemistry, Chinese Academy of Sciences; the ferromanganese crust samples were collected by R/V Dayang No. 1 during D Y105-11 cruise and provided by China 0cean Repository. This work was supported by China 0cean Mineral Resources Association （Grant Nos. DY105-01-04-08, DY105-01-04-02） and the National Natural Science Foundation of China （Grant No. 40173027）.
Based on results of nannofossil analysis and 10Be dating in ferromanganese crusts M1-1 and A1-1 (no nannofossils were found in it),from the western and central Pacific respectively,it is found that the crust growth ag...
