This study shows lithosphere evolution history in the west North China Craton (NCC) from the early Cretaceous to Quaternary by studying the major element, trace element and Sr-Nd-Hf isotope compositions in Jining basalts of 119.6108.6 Ma, 23.521.9 Ma and 1.30.11 Ma.The early Cretaceous basalts (119.6108.6 Ma) display enriched characteristics with high contents of incompatible elements, high 87 Sr/ 86 Sr i , low ε Nd (t) and low ε Hf (t). These basalts resulted from partial melting of ancient metasomatized lithospheric mantle, and we consider the 119.6108.6 Ma magmatism as indicating lithosphere thinning in the west NCC. Although the Pacific slab seen seismically in the mantle transition zone beneath eastern China is no older than 60 Ma, there exists convincing evidence for the presence of the Paleo-Pacific slab in the transition-zone in the Mesozoic. Thus we propose that the water released from the transition-zone slab hydrated A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPTthe overlying lithosphere and further converted the base of the lithosphere into asthenosphere. This is the most likely mechanism responsible for the lithosphere thinning in the west NCC and the petrogenesis of the Jining 119.6108.6 Ma basalts. Sr i , high ε Nd (t) and high ε Hf (t). Upwelling and decompression melting of the eastward flowing asthenosphere from beneath western plateaus to beneath eastern hilly plains in the Cenozoic is the most plausible mechanism for the petrogenesis of Jining Cenozoic basalts (both of 23.521.9 Ma and 1.30.11 Ma), but the Jining 1.30.11 Ma basalts must have been produced beneath even thinner lithosphere.Taken together geophysical studies and our petrological and geochemical studies of all these three episodes of the Jining basalts, wepropose that the lithosphere in the west NCC has been thinning since the early Cretaceous and the thinning continues to the present.

“…Back-arc extension continued into the Quaternary, associated with the central eruption style of the Neogene-Quaternary basaltic lavas in NE China (e.g. Basu et al, 1991;Liu et al, 2001;Lei and Zhao, 2005). Apatite FT data from the Songliao Basin, adjacent to the Dahinggan Mountains, indicate that the late stage tectonic movements in the Songliao Basin have zoning in space and episodes in time (Xiang et al, 2007).…”

“…Sources of potassic basalts were referred to the enriched post-Archean sub-continental lithospheric mantle, comparable to the global EM1 OIB component, unlike sources of potassic-sodic basalts that were considered as derivatives from the depleted sub-lithospheric mantle, comparable with the depleted global DMM OIB component [Zhang et al, 1995;Zou et al, 2003Zou et al, , 2008Choi et al, 2006;Chen et al, 2007;Chu et al, 2013]. Significant discrepancies were found between geochemical signatures of mantle xenoliths from potassic-sodic basalts of China and their host lavas [Basu et al, 1991]. On the contrary, geochemical characteristics similar (although not identical) to those of host lavas were defined in xenoliths of spinel peridotites from potassic volcanic rocks [Zhang et al, 2000[Zhang et al, , 2011Chu et al, 2013].…”

Introduction. Transtension is a system of stresses that tends to cause oblique extension, i.e. combined extension and strike slip. Syn-volcanic transtensional deformations of the lithosphere may provide two possible scenarios for control of magmatic processes. One scenario assumes ascending sub-lithospheric melts that mark the permeable lithosphere in a transtension area without melting of the lithospheric material; products of volcanic eruptions in such a zone show only the sub-lithospheric mantle material; components of magmatic liquids do not reveal any connection to the lithospheric structure. Another scenario yields a direct control of melting in lithospheric sources in an evolving transtensional structure. In this case, spatial-temporal changes of lithospheric and sub-lithospheric components are a direct indication of the evolving transtensional zone. In this paper, we present arguments in favor of the transtensional origin of the lithosphere-derived melting anomaly along the Wudalianchi volcanic zone, which are based on the study of components in the rocks sampled from the volcanic field of the same name.Analytical methods. Trace elements were determined by ICP-MS using a mass-spectrometer Agilent 7500ce and isotopes using a mass-spectrometer Finnigan MAT 262. The methods used were described in the previous papers by Rasskazov et al. [2011] and Yasnygina et al. [2015]. Major oxides were measured by "wet chemistry".Structural setting of the Wudalianchi zone. This zone extends north-south for 230 km at the northern circuit of the Songliao basin, subsided in the Late Mesozoic -Early Cenozoic (Fig. 1).Timing of volcanism and variations of K2O contents in rocks from the Wudalianchi zone. Rocks, dated back to the Pliocene and Quaternary, show the stepwise increasing K2O content interval along the Wudalianchi zone from the southernmost Erkeshan volcanic field (5.6-5.8 wt %) to the northernmost Xiaogulihe-Menlu volcanic field (2.0-9.5 wt %) (Fig. 2).Spatial-temporal clustering of volcanoes in the Wudalianchi field. In terms of the general Quaternary evolution of volcanism in Asia [Rasskazov et al., 2012], spatial-temporal distribution and compositional variations of volcanic products, we distinguish three time intervals of the volcanic evolution: (1) 2.5-2.0 Ma, (2) 1.3-0.8 Ma, and (3) <0.6 Ma. The Central group of volcanoes showed persistent shifting of eruptions from Wohushan (1.33-0.42 Ma) to to Laoheishan (1720-1721, possibly earlier) to Huoshaoshan (1721) (Figs 3, 4, 5). No spatial-temporal regularity of eruptions in volcanoes of the Erkeshan field and Western and Eastern groups of the Wudalianchi field reflected background activity.Sampling. Representative sampling of rocks from the Wohushan-Huoshaoshan volcanic line was aimed to identify changing geochemical signatures along the whole volcanic line and in the course of eruptions in each volcano (Figs 3, 6, 7). For comparisons, the background volcanoes were also sampled.Silica and alkalis oxides. On the total alkalis-silica (TAS) diagram (Fig. ...
