Journal ArticleDOI
Geochemical, Sr-Nd and zircon U-Pb-Hf isotopic studies of Late Carboniferous magmatism in the West Junggar, Xinjiang: Implications for ridge subduction
Hongyan Geng,Min Sun,Chao Yuan,Wenjiao Xiao,WS Xian,Guochun Zhao,Lifei Zhang,KP Wong,Fu-Yuan Wu +8 more
TL;DR: In this article, the authors classified voluminous granitic intrusions in the West Junggar, NW China, and they can be classified as the dioritic rocks, charnockite and alkali-feldspar granite groups.
Journal ArticleDOI
Late Carboniferous high-Mg dioritic dikes in Western Junggar, NW China: Geochemical features, petrogenesis and tectonic implications
TL;DR: In this article, the authors found that high-Mg dioritic dikes widely occur in western Junggar, NW China and are enriched in SiO2 (52-57 wt.%), and characterized by high MgO (5.13-7.41 wt.).
Journal ArticleDOI
Geochemical and geochronological study of early Carboniferous volcanic rocks from the West Junggar: Petrogenesis and tectonic implications
TL;DR: In this paper, a series of early Carboniferous volcanic rocks, i.e., basalt, andesite, and dacite, occur in the West Junggar and are interpreted to be derived from a slightly metasomatized depleted mantle in a normal subduction environment.
Journal ArticleDOI
Kinematics and age constraints of deformation in a Late Carboniferous accretionary complex in Western Junggar, NW China
Ji'en Zhang,Wenjiao Xiao,Chunming Han,Songjian Ao,Chao Yuan,Min Sun,Hongyan Geng,Guochun Zhao,Qianqian Guo,Chong Ma +9 more
TL;DR: In this article, the authors conclude that the overall movement in the accretionary complex was top-to-the-NW, based on detailed field mapping and analyses of the asymmetry of imbricate thrusts, duplexes, tilted structures, shear band cleavages, and the NW-verging inclined to overturned folds.
