| Abstract: | In this paper, we systematically summarized two large stages and seven eruptive phases of the Changbaishan volcano. The accumulation types of deposits and the characteristics are classified, Meanwhile, mechanism and evolutionary process are discussed. The existence of base surge accumulation of the Changbaishan volcano is proposed for the first time. The newly found intrusive phase and subvolcanic phase are compared with extrusive phase, indicating that they were derived from the same analkali magmatic chamber. |
