Abstract: According to the results of multidisciplinary analyses with different methods, we found that there were at least four hiatuses ina sediment core taken from CC Zone in North Pacific. These hiatuses are as follows: Holocene, Middle Pleistocene, UpperPliocene and Middle Miocene. The main cause of these hiatuses is the Antactic Bottom Water (AABW). There were three layers of polymetallic nodules in this sediment core. They were the surface nodules, the buried nodules inthe depth of 28cm and 320cm in the mre respectively. These nodules were different in the size, chemical composition, mineralphases and age, but the origin of these nodules were all related to the hiatus in 320cm of the core which began at 1.2 X 107a BP.
