Triassic granitoids in the East Kunlun Orogenic Belt, Northwestern China: magmatic source and implications for geodynamic evolution

Zhi-He Xu et al.

Summary: Granitoids are important evidence of the accretion and reworking process of the continental crust. By analyzing their geochemical characteristics, the early geodynamic mechanisms can be reconstructed. This study focused on the Permian-Triassic Granitoids in the East Kunlun Orogenic Belt and determined their chronology and petrogenesis, shedding light on their source regions and the significance of their geodynamic and crustal growth.

Triassic igneous activities in the east flank of the East Kunlun orogenic belt: the Daheba complex example

Nan Tian et al.

Summary: Through the study of petrology, mineral chemistry, geochemistry, and isotopes of Triassic igneous complexes in the east flank of the East Kunlun orogenic belt, we reveal the precise timing and petrogenesis of the magmatism in this region. Our findings show that the rocks exhibit characteristics of subduction-related magmatism, with the fine-grained granites being highly fractionated I-type granitoids. The presence of mafic microgranular enclaves and their similarity to the host granites suggest magma mixing.

Volcanic rocks of the Elashan Formation in the Dulan-Xiangride Basin, East Kunlun Orogenic Belt, NW China: Petrogenesis and implications for Late Triassic geodynamic evolution

Xingzhu Fan et al.

Summary: The volcanic rocks of the Elashan Formation in the Dulan-Xiangride Basin during the Late Triassic exhibit characteristics of calc-alkaline I-type dacite, peraluminous rhyolites, and andesite formed from the partial melting of the Late Paleoproterozoic-Mesoproterozoic lower crust. The combination of new and previously obtained geological data suggests that the East Kunlun Orogenic Belt underwent three magmatic activities corresponding to three tectono-magmatic events during the Late Triassic, including slab breakoff and intense asthenosphere upwelling.

Geochronology, geochemistry, and Hf isotopic compositions of Triassic igneous rocks in the easternmost segment of the East Kunlun Orogenic Belt, NW China: implications for magmatism and tectonic evolution

Dong-Qian Wu et al.

Summary: This study investigates the geochronology and petrogenesis of igneous rocks in the East Kunlun Orogenic Belt, revealing the unique geological characteristics and tectonic evolution of the Elashan area. The 238 Ma syenogranites, 236 Ma quartz monzodiorites, and 230 Ma appinites have distinct origins and formation processes, reflecting changes in tectonic environments and associated magmatic activities. These rocks were likely emplaced during syn-collisional slab break-off and initial post-collisional extensional settings.

Petrogenesis and tectonic setting of Mid-Triassic volcanic rocks in the East Kunlun orogenic belt, NW China: Insights from geochemistry, zircon U-Pb dating, and Hf isotopes

Nan Tian et al.

Summary: The Elashan magmatic belt in Northwestern China is located at the eastern margin of the East Kunlun Orogenic Belt, where voluminous magmatism occurred from the Late Permian to Late Triassic. The rocks in this region, particularly the Xilikete Formation, exhibit geochemical characteristics of highly fractionated I-type volcanic rocks, indicating HFI volcanic rocks. The magmatism in this region was likely triggered by the subduction of the Palaeo-Tethys oceanic plate around 240 million years ago.
