The Cambrian period marks a crucial phase in the initial subduction of Proto-Tethys Ocean beneath East Kunlun Orogen. Studying I-type granites and mafic–ultramafic rocks formed during this can provide valuable insights into early Paleozoic tectonic evolution region. This paper incorporates petrology, LA-ICP-MS zircon U-Pb geochronology, whole-rock major trace element data obtained from Kekesha intrusion eastern section formation age, petrogenesis, magmatic source region are revealed, process...
The formation of early Mesozoic granitoid plutons in the Qinling Orogen is widely regarded as a result collision and accretion between Yangtze Block South during Mesozoic, but specific magmatic process, source composition, tectonic environment deep dynamic background remain controversial. This study reports petrology, zircon U–Pb geochronology, whole-rock geochemistry diorites from Liuba Qingyangyi Qinling, to provide new evidence for understanding final evolution process Orogenic belt....
Mid-Neoproterozoic rift-related Tadong amphibolites (TDA) are situated in the junction of East Kunlun Orogen (EKO) and West Qinling (WQO) western China, have important significance break-up Supercontinent Rodinia. The mineral assemblage TDA exhibits amphibolite facies metamorphism, protolith is basic volcanic rocks. Here, we present a detailed laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) zircon U–Pb age geochemical data TDA. LA-ICP-MS determination indicates that...
A significant amount of pegmatite has been discovered on the northwest margin Qaidam basin. Among this, Jiaolesayi pegmatite, located in northwestern Quanji Massif (Oulongbuluke micro-continent), shows rare element mineralization potential. Detailed field investigations, along with mineralogical, geochemical, and zircon U-Pb geochronological studies, were carried out pegmatite. The results show that is syenite, without obvious compositional zoning outcrop. It exhibits a peraluminous, high-K...
The main ocean–continent transformation stage of the Qinling and Qilian conjunction zone happened in Early Paleozoic with occurrence a lot subduction–collision–related magmatic rocks. However, there is still considerable controversy over duration subduction–collision orogeny process Proto-Tethys Ocean, here termed as Wushan–Shangdan Ocean. We provide geochronological, geochemical, Lu-Hf isotopic data for typical Devonian igneous rocks there, named Tailu pluton. pluton at 410 Ma comprised...
Abstract. The Liqiao and Xianping plutons can provide crucial evidence for the collision-orogeny process of Proto-Tethys Ocean in western section North Qinling Orogen. In this study, we present petrological, zircon U-Pb geochronological, geochemical, Lu-Hf isotopic data these plutons. Both are characterized as high-K, calc-alkaline, metaluminous to weakly peraluminous granites, with ages 429 Ma 421 Ma, respectively. pluton was classified I-type granite, displaying positive εHf(t) values...
Abstract Sediments within accretionary complexes, preserving key information on crust growth history of Central Asian Orogenic Belt, did not get enough attention previously. Here, we conduct comprehensive geochemical study the turbidites from North Tianshan Accretionary Complex (NTAC) in Chinese West orogen, which is a good example sediments derived juvenile materials. The turbidites, composed sandstone, siltstone, and argillaceous siliceous rocks, are mainly Carboniferous. All investigated...
