“…The major and trace element data of the Triassic–Middle Jurassic granitoids in the study area provide valuable information regarding the nature of their magma source. These granitoids contain high SiO 2 (68.94–77.07 wt.%) and low MgO (0.07–0.98 wt.%) concentrations and are depleted in Nb, Ta, P, and Ti and enriched in Rb, Th, and K, indicating that the formation of these rocks can be attributed to the partial melting of the crust (Gao et al, ; Chappell & White, ; Yang et al, ; H. W. Cao et al, ). The following points also prove this viewpoint: (a) the Ce/Pb and Nb/U ratios of the studied granitoids are 0.78–6.86 (average 2.94) and 2.70–10.76 (average 6.83), respectively, suggesting a continental crust source (Hofmann, Jochum, Seufert, & White, ); (b) these rocks have Rb/Sr ratios of 0.20–2.89 (an average of 0.86), Ti/Zr ratios of 3.40–13.46 (an average of 9.94), and Ti/Y ratios of 113.11–382.61 (an average of 265.49; Table ), which are consistent with the magma derived from the partial melting of crust (Pearce, ; Tischendorf & Paelchen, ; Wilson, ); and (c) the low concentrations of compatible elements (e.g., Cr, Co, and Ni) and low Mg # values (11–41) in these samples indicate that the primary magma of the granitic rocks in the Qingchengzi district was formed by the partial melting of the lower crustal materials (Rapp, Shimizu, Norman, & Applegate, ; Rapp & Watson, ).…”

Herein, new zircon U-Pb ages, whole-rock major and trace element geochemistry, and Hf isotopes are presented for four Mesozoic granitic rock samples within the Qingchengzi district, eastern China. These data provide precise age and petrogenesis information with respect to the Mesozoic intrusions in the Qingchengzi district, which further constrain the initial decratonization process of the eastern North China Craton (NCC). The zircon U-Pb data reveal that these granitoids are emplaced in the following two stages: Triassic (243-220 Ma) and Middle Jurassic (∼164 Ma). These Mesozoic rocks (lithology: syenogranite, monzogranite, and biotite granite) contain high concentrations of silica (68.94-77.07 wt.%) and total alkali (7.35-9.71 wt.%) together with low concentrations of MgO (0.07-0.98 wt.%), total Fe 2 O 3 (0.81-2.92 wt.%), and CaO (0.17-1.80 wt.%), and they are characterized by an enrichment of large-ion lithophile elements (LILEs; e.g., Rb, Cs, and K) and light rare earth elements (LREEs)in addition to depletion of high-field-strength elements (HFSEs; e.g., Nb, Ta, and Ti) and heavy rare earth elements (HREEs), indicating that these Mesozoic rocks are similar to I-type granitoids. The ε Hf (t) values of the magmatic zircons in these granitoids range from −18.7 to −11.4. Such geochemical characteristics indicate that these granitoid formations were generated by the partial melting of the ancient lower crustal material. However, the occurrence of mafic microgranular enclaves in the Shuangdinggou monzogranite implies the mixing of the mantle-derived magmas.Combined with the results of the previous research, these new data indicate that initial decratonization of the eastern NCC occurred during the Triassic period in response to the collision and amalgamation of the Yangtze Craton and NCC. During the Jurassic, the dynamic mechanism of lithospheric thinning was overprinted owing to the subduction of the Paleo-Pacific Plate. Furthermore, cratonic destruction reached its peak during the Early Cretaceous, which could be related to the asthenospheric upwelling induced by the rollback of the subducting oceanic slab.[Correction added on 21 October 2019, after first online publication: Funding information has been added.]

In recent years, the main grain-producing areas in the west of Jilin have gradually concentrated in the perennial irrigation areas and supplementary irrigation areas in the north, and the stress degree of grain irrigation water resources is gradually increasing. Therefore, this paper selects the arid and semiarid area in the west of Jilin Province as the research area and compares and analyzes the modeling process and simulation accuracy of the temporal and spatial distribution of food security production and total water resources. Based on the center of gravity model, this paper studies the temporal and spatial distribution of food security production and total water resources in Western Jilin. It can be seen that after 2018, rice and wheat show a fluctuating upward trend, and their values rise from 0.612 to 0.786 and 0.356 to 0.612, respectively; the rise of corn is small, showing an inverted “U” trend, which first increases from 0.693 in 2018 to 0.701 in 2019 and then decreases to 0.671 in 2021; By comparing the precipitation statistics in different years, the inverted “U” trend of corn irrigation water efficiency may be related to the sudden increase of precipitation. The center of gravity model is used to analyze the evolution trend of the center of gravity of grain production and water resources in Western Jilin from the national and regional levels, and the spatiotemporal coupling degree of the center of gravity of grain production and water resources is explored through the two-factor center of gravity coupling situation model.

“…7): The Songliao and Jiamusi blocks completed their first assemblage in the Early Paleozoic Liu et al, 2017), and remained as an united Block till the end of the Permian (Meng et al, 2010;Xu et al, 2012). At the end of Permian, due to the eastward subduction of Paleo-Pacific Ocean (Zhou et al, 2009;Sun et al, 2015;Yang et al, 2015Yang et al, , 2017Bi et al, 2016Bi et al, , 2017, the Songliao-Jiamusi united Block was in a back-arc extension setting and broken up probably along the Paleozoic suture zone, resulting in the re-opening of the Mudanjiang Ocean. Due to the continuous subduction of the Paleo-Pacific Ocean, the short-lived Mudanjiang ocean was closed again in sometime between the Middle Jurassic and Early Cretaceous (Wu et al, 2007;Li et al, 2009Li et al, , 2011Zhu et al, 2017 a, b, c;Dong et al, 2018b).…”

Central Asian Orogenic Belt (CAOB) is one of the largest accretionary orogenic belts in the world. The eastern segment of CAOB is dominated by Paleozoic Paleo Asian Ocean tectonic regime, Mesozoic Paleo‐Pacific tectonic regime and Mongolian‐Okhotsk tectonic regime. The Songliao and Jiamusi blocks are located in the easternmost part of the CAOB and are the key region to solve the problem about overprinting processes of multiple tectonic regimes. It is generally believed that the Mudanjiang Ocean between the two blocks was finally closed in the Mesozoic, but the Paleozoic magmatism also developed along the Mudanjiang suture zone, while on both sides of the suture zone, there were comparable Paleozoic strata, indicating that the two blocks had converged during the Paleozoic, and the evolution history of the two blocks in the Late Paleozoic remains controversial. The Carboniferous‐Permian terrestrial strata mainly developed in Binxian, Wuchang and Tieli on Songliao Block, Baoqing and Mishan on Jiamusi Block. Samples from the Songliao and Jiamusi blocks in the Late Carboniferous‐Early Permian and Late Permian are collected for comparative analysis. The LA‐ICP‐MS zircon U‐Pb dating results show that the maximum depositional age of Middle Permian Tumenling Formation and Late Permian Hongshan Formation in Songliao Block is ∼260 Ma, while that of Tatouhe Formation and Carboniferous strata in Jiamusi Block are ∼290 Ma and ∼300 Ma, respectively, which supports the previous stratigraphic division scheme. The age peaks of ∼290–300 Ma, ∼400 Ma, ∼500 Ma appeared in the Late Carboniferous to Early Permian strata of Jiamusi Block and the Middle Permian strata of Songliao Block. The age peak of ∼500 Ma in the Middle Permian strata of Songliao Block may come from the Cambrian basement, Mashan Complex, of Jiamusi Block, while the age peaks of ∼420–440 Ma in the Carboniferous strata of Jiamusi Block may come from the Silurian magmatic arc in Zhangguangcai Range in the eastern margin of Songliao Block, reflects the history that they had been potential sources of each other, indicating that they may have combined in the Paleozoic. The Hongshan Formation of Songliao Block in the Late Permian lacks the age peak of ∼500 Ma, which indicate that Jiamusi Block was not the provenance of Songliao Block in the Late Permian, that is, there was a palaeogeographic isolation between the two blocks. Combined with the ∼210 Ma bimodal volcanic rocks developed along the Mudanjiang suture zone reported previously, we believe that the oceanic basin between the Songliao and Jiamusi blocks should have been connected in Late Permian and reopened during Late Permian to Late Triassic.
