The research leads to following conclusions: A The age of the ferromanganese contacting with the upper phosphate layer is 14.9 Ma; B The crust had been grown continually without sedimentation interruption since 14.9 Ma, suggesting that it can be used to rebuild the environment of palaeo-ocean and palaeo-climate from 14.9 Ma to 0 Ma; C The sedimentation interruption between the ferromanganese and the upper phosphate layer lasted around 4 Ma; D Between 19 Ma and 22.7 Ma, great phosphatization event happened in this area, which might cause the sedimentation interruption from 22.7 Ma to 14.9 Ma; E The ferromanganese crust began to grow from 75 Ma.

对超微量Sr同位素测试得到的富钴结壳磷酸盐年龄进行分析认为：(1)上部富钴结壳与上层白色磷酸盐化层接触部位的年龄为14.9 Ma；(2)自14.9 Ma以来，结壳的生长是连续的，沉积间断发生的可能性非常小，该样品可以用来进行14.9 Ma年以来古海洋、全球变化的重建工作；(3)上层白色磷酸盐化层与其上部的富钴结壳之间存在4 Ma的沉积间断；(4)19 Ma~22.7 Ma左右在该区发生过大规模的磷酸盐化作用，磷酸盐化作用可能造成磷酸盐化时期(19 Ma~22.7 Ma)和之后4 Ma(19 Ma~14.9 Ma)富钴结壳的沉积间断；(5)结壳的初始生长年龄在75 Ma左右；(6)老结壳的生长速度要远低于新结壳的生长速度。
