Abstract: Volcanic magma eruption in Tianchi of Changbai Mountain run through the whole Quaternary period. It is characterzied by distinct eruption cycle and well developed glacier relics, providing beneficial conditions for the study of coupling relation between volcanic eruption and glaciation. This paper analyzed eruption cyclic of Quaternary volcanos and distribution characteristics of volcanic rocks using collecting the chronological statistic data of volcanic eruptions and the cycle of ice age and interglacial, along with superposition relationship between volcanic eruption and ice erosion U-shaped valley. Based on the chrological data and the well-developed U-shaped valey around Tianchi volcanic cone, the glaciaton can be divided into three ages: Jingjiang Ice Age, Manjiang Ice Age and Erdaobaihe Ice Age, in response to Poyang Ice Age, Dagu Ice Age and Lushan Ice Age in the eastern of China, respectively. Eruption of Tianchi volcano in Changbai Mts formed three stages of Baitoushan Formation(Ⅰ. Ⅱ. Ⅲ), which couple well with three Ice Ages mentioned above. The ice cirque in Tianchi formed during Baitoushan Ice Ages(i.e. Dongshan Ice Age, MIS4, in the eastern of China). Even experiencing double transformation during Heifengkou Ice Age and Qixiangzhan Ice Age(Mengshan Ice Age, MIS2, in the eastern of China), and Holocene glaciation and volcanism, its basic features have been preserved until today. Ice sheet melting of Changbai Mts resulted in rebounding of pressure release, which may induce the cyclic eruption of Tianchi volcano.
