英文摘要	In the Mesozoic, the Northeast (NE) China experienced transformation from Mongol-Okhotsk (MO) to circum-Pacific tectonic regime, forming different temporal volcanic activities. This paper summarizes geochoronology, spatial-temporal variations, association and geochemistry, with the aim to constrain evolution of those two regimes. Together with previous information, U-Pb age data indicate that Mesozoic volcanism in NE China can be subdivided into five episodes: Early-Middle Jurassic (190 similar to 160Ma), Late Jurassic (160 similar to 145Ma), early Early Cretaceous (145 similar to 120Ma), late Early Cretaceous (120 similar to 100Ma), and early Late Cretaceous (100 similar to 90Ma). The Early-Middle Jurassic volcanic rocks, occurring not only in the Lesser Xing' an-Zhangguangcai Ranges and western Liaoning Province, but also in the Manzhouli region, belong chemically to the high-k calc-alkaline series, implying the double subduction of MO oceanic plate and Farallon plate. Volcanic rocks of Late Jurassic mainly occur in the Great Xing' an Range (GXR), and a little in the Lesser Xing' an Range (LXR) and Zhangguangcai Range. The volcanic rocks in GXR which are trachyandesite and trachyte imply syn-collisional setting, and they were due to collisional orogeny accompanied the closure of MO Bay, and those in LXR and Zhangguangcai Range are intermediate-silicic rocks, which are formed under an extensional environment related to the deviation of Farallon plate. The most widespread volcanism in NE China was during in the early Early Cretaceous. Volcanic rocks largely distributed in GXR and around Songliao Basin are trachy-basaltic andesite, trachyandesite, andesite, trachyte and so on, which belong chemically to high-K calc-alkaline series and post-orogenic tectonic setting. The rocks formed during delamination of a thickened continental crust related to the post-orogenic diffuse extension due to the closure of MO suture bay. In the late Early Cretaceous, volcanism in GXR gradually decreased, whereas those in Songliao Basin increased. The volcanic rocks belong chemically to high-K calc-alkaline series and within plate setting, which formed under an extensional environment related to a backarc setting accompanied a low angle subduction of the Kula-Izanagi plate underneath the Eurasian continent. In the early Late Cretaceous, volcanic rocks were limited to the LXR and eastern Jilin-Heilongjiang provinces, and they are consist of medium-K calc-alkaline rocks such as basalt, basaltic andesite, andesite and dacite, implying active continental margin setting. Volcanism in early Late Cretaceous was affected by right-lateral strike-slip motions in continental margin in process of the oblique subduction of the Kula-Izanagi plate. Taking all this into account, we can conclude that the Mesozoic volcanism in Northeast China was both controlled by the closure of MO Bay and subduction of Paleo-Pacific plate. Mesozoic volcanic rocks were tectonic overprint that MO regime transferred to the circum-Pacific regime.
