“…Zhang et al 2010;Li et al 2012;Sun et al 2012;Kiminami & Imaoka 2013).These subduction episodes produced subduction related volcanic rocks and granitoids over hundreds of millions of years that are widespread in the Great Xing'an Range. In the late Mesozoic the Palaeo-Pacific subduction and slab rollback underneath NE China controlled much of the volcanism.…”

“…Mantle upwelling associated with slab rollback and backarc return flow initiated the Songliao Basin, a series of interconnected half-grabens, at about 157 Ma (e.g. Zhang et al 2010;Trujillo 2013). In many ways the tectonics of NE China during the late Mesozoic is reminiscent of the tectonics of western North America during the Cenozoic (Trujillo 2013).…”

S U M M A R YThe 127 station NorthEast China Extended SeiSmic Array (NECESSArray) provides large quantities of high quality seismic data in northeast China that allow us to resolve lateral variations of Lg Q or crustal attenuation at 1 Hz (Q o ) to 2.0 • or greater. Using the reverse two-station/event method with 11 642 Lg path-amplitudes from 78 crustal earthquakes, we obtain a 2-D tomographic image of Lg Q o with values ranging from ∼50 to 1400. A high degree of detail in the lateral variation of Lg attenuation is revealed in our tomographic image. High Q o regions are found in the Great Xing'an, Lesser Xing'an and Songen-Zhangguangcai Ranges. Low Q o regions are observed in the Songliao, Sanjiang and Erlian Basins. The lowest Q o is found near the Wudalianchi volcanic field and other Quaternary volcanic fields, the southern Songliao Basin, the western edge of the Erlian Basin and the Sanjiang Basin. Low Q o values are measured for paths that cross sedimentary basins with thick, unconsolidated sediments. Most of the high Lg attenuation in the Songliao Basin correlates reasonably well with low crustal Rayleigh wave phase velocity anomalies. The highest attenuating regions also correlate well with regions of Holocene volcanism.Key words: Tomography; Heat flow; Earthquake ground motions; Seismicity and tectonics; Guided waves; Seismic attenuation; Seismic tomography. I N T RO D U C T I O NThe Lg wave is the most prominent high frequency (f > 0.5 Hz) regional phase observed at regional distances. It has a group velocity of about 3.5 km s -1 in northeast China and can be modelled as the sum of higher mode surface waves (Oliver et al. 1955;Knopoff et al. 1973;Herrmann & Kijko 1983) or as many supercritically reflected crustal S waves (e.g. Bouchon 1982). This wave only propagates efficiently over continental paths and can be seen at distances up to 30 • in the Canadian Shield (Hasegawa 1985). The study of Lg wave attenuation has often been used for characterizing crustal structure since the sensitivity of the Lg wave to crustal properties makes it an important tool in better understanding the underlying causes of seismic anomalies in the crust (Ruzaikin et al. 1977;Ni & Barazangi 1983;Xie & Mitchell 1990;McNamara et al. 1996;Xie 2002;Zor et al. 2007;Phillips & Stead 2008;Zhao et al. 2010;Bao et al. 2012). Lg attenuation is also an important factor in determining seismic hazard since the large amplitude of the Lg wave is capable of causing structural damage at regional distances (Campillo et al. 1989).Early efforts to map crustal attenuation relied on the temporal decay rate of the Lg coda (e.g. Singh & Herrmann 1983). In these studies source effects were model dependent and site effects, which are due to the near surface effect of sediments and the focusing and defocusing of the seismic waves, were omitted. Furthermore, efforts at understanding Lg attenuation have been restricted to modelling it as if only geometric spreading and attenuation affect the amplitude, while in reality, the Lg wave train is much more comp...

“…The volcanic rocks in the southern GXM are mainly distributed in several discrete basins, including the Baoshi, Pingshan and Wudan basins, and have been subdivided into the Manketouebo, Manitu, Baiyingaolao and Meiletu formations (Fig. 2;IMBGMR, 1991;Ying et al, 2010;Zhang et al, 2010). The Manketouebo formation is widely distributed and mainly composed of rhyolite, dacite, volcaniclastic rock and rhyolitic tuff.…”

“…The widespread volcanic rocks in the southern GXM are mainly sub-alkaline and show characteristics of calc-alkaline and shoshonitic series. Recent geochronological studies indicate the volcanic rocks in the Great Xing'an area were mainly erupted in the Early Cretaceous (Wu et al, 2005;Wang et al, 2006;Zhang et al, 2010). In this study, we systematically investigate a suite of calc-alkaline and shoshonitic volcanic rocks from the southern GXM on geochronology and geochemistry.…”

“…100,000 km 2 (Ying et al, 2010), and mainly distribute along the GXM. Numerous geological, petrological and geochronological studies were carried out on these large-scale magmatic activities (Jahn et al, 2001;Fan et al, 2003;Wu et al, 2005;Wang et al, 2006;Zhang et al, 2008aZhang et al, , 2008bZhang et al, , 2010Guo et al, 2010;Yang et al, 2013), which have not resulted in a consensus about the mechanism. There are several models has been proposed to interpret this extensive Mesozoic magmatism, including: mantle plume hypothesis (Lin et al, 1998;Ge et al, 1999), post-orogenic diffuse extension after the subduction of the Mongol-Okhotsk Ocean (Fan et al, 2003;Gao et al, 2005;Guo et al, 2010), thickened lithospheric delaminating induced by the subduction of Pacific plate (Wu et al, 2005;Wang et al, 2006;Zhang et al, 2010).…”

The Wandashan Orogen of NE China is a typical accretionary orogen related to Paleo-Pacific subduction. The Raohe Complex, as a major part of the orogen, consists of mid-Triassic to mid-Jurassic radiolarian chert and intraoceanic igneous rocks in an accretionary prism overlain by weakly sheared terrestrial-sourced clastic trench slope sediments. Sensitive high-resolution ion microprobe U-Pb dating and LA-MC-ICPMS Hf isotopic analysis of detrital zircons from the terrestrial-sourced Yongfuqiao Formation sandstone show that most zircons are Phanerozoic (90%): 140-150 Ma (10%), 180-220 Ma (25%), 240-270 Ma (15%), 300-360 Ma (15%), 391-395 Ma (3%), and 450-540 Ma (20%), whereas 10% are Precambrian in age. About 90% of the zircons have ε Hf (t) values ranging from +11.1 to À12.8. This suggests that the major provenance of the trench slope sediments was from the adjacent eastern segment of the Central Asian Orogenic Belt and the Jiamusi Block. The age of the Yongfuqiao Formation is constrained to the earliest Cretaceous, which represents the accretion time of the mid-Triassic to mid-Jurassic oceanic complexes. When compared with the Mino Complex in Japan and the Tananao Complex in Taiwan, three different provenances are identified suggesting three ancient drainage systems which transported sediments from NE China, North China, and South China to the Paleo-Pacific subduction-accretion system.
