The central Great Xing'an Range contains widespread exposures of Mesozoic igneous rocks, yet the origin its Late volcanic rocks has long been controversial. They are composed andesite, trachyte, trachyandesite, trachydacite, rhyolite, and minor basaltic andesite. intermediate enriched in large ion lithophiles light rare earth elements (LILEs LREEs) depleted high field strength (HFSEs) such as Nb, Ta, Ti, with positive εHf(t) values (+6.2 to +13.4) Hf single-stage model ages (TDM1 = 556–227...
In this paper, we report on LA‐ICP‐MS zircon U–Pb dates of 14 Mesozoic volcanic rocks from the central Great Xing'an Range (CGXR). These data are integrated with temporal and spatial distribution local magmatism‐related mineralization, in an effort to develop understanding geodynamic evolution region. Periodic magmatic events GXR date ~1,703 through ~145 Ma. volcanism CGXR can be subdivided into three episodes: Triassic (250–205 Ma), Early–Middle Jurassic (182–165 Late Jurassic–Early...
The Tayuan plutons located at the boundary of Erguna and Xing'an blocks expose a coexisting mafic–felsic association that is made monzogranite gabbro-monzodiorite as well subordinate quartz monzonite. LA–ICP–MS U–Pb zircon dating revealed synchronous emplacement (314–317 Ma), gabbro (308–315 monzonite (310 ± 3 Ma). majority these intrusions are characterized by an enrichment in light rare earth elements relative to heavy depletion high strength field (e.g. Nb, Ta, Ti). Zircons from have...
This paper presents major element, trace and new zircon Hf isotopic data for the Early Mesozoic intrusive rocks in south Hunchun, Yanbian area, Northeast China. These are used to constrain petrogenesis of these their implications Phanerozoic continental growth Central Asian Orogenic Belt (CAOB). Combining geology, geochronology, whole-rock geochemistry, we identify three distinct episodes magmatism as Early–Middle Triassic (249–237 Ma), Late (224–206 Jurassic (200–187 Ma). The Ma) adakitic...
This study presents new zircon U–Pb ages, Sr–Nd–Hf isotopic data, and whole‐rock geochemical data obtained from the Early Cretaceous volcanic rocks north‐western Great Xing'an Range, Northeast China, to constrain late Mesozoic magmatism geodynamic setting of this region, which is located in eastern segment Central Asian Orogenic Belt (CAOB). Zircon age determinations show that studied samples formed at 124–114 Ma with an magmatic event produced voluminous felsic minor mafic rocks. The are...
Abstract In this study, new geochemical, zircon U–Pb, and Lu–Hf isotopic data are presented for volcanics from the Hadataolegai Formation of central Great Xing'an Range (GXR) in Northeast China. These offer insights into petrogenesis tectonic evolution Paleo–Asian Ocean (PAO) Mongol–Okhotsk (MOO). divided andesite‐trachyandesites dacite‐trachydacites. Zircon U–Pb ages show that erupted between 230 Ma 228 during Late Triassic, which agrees with recently obtained data. The volcanic rocks study...
The Ordovician plutons in the Erguna Block, NE China, can be classified into two groups: Early diorites with zircon U–Pb ages ranging from 486 to 485 Ma and Middle gabbros granites 466 463 Ma. are calc-alkaline nature characterized by weak moderate enrichments of large ion lithophile elements (LILE) light rare earth (LREE) relative high field strength (HFSE) heavy (HREE). have total alkali contents, all samples enriched LREE LILE depleted HFSE such as Nb, Ta, Ti. Isotopically, display values...
Triassic magmatism in Northeast (NE) China was geodynamically controlled by the Mongol–Okhotsk Ocean (MOO), Palaeo-Asian (PAO), and Palaeo-Pacific (PPO) tectonic regimes. To define mechanisms of crustal accretion geodynamics, magmatic processes generated ocean closure plate subduction must be determined. In present study, we assembled geochronological, geochemical, Cu (Mo)-porphyry deposit, zircon Hf isotopic data from rocks throughout NE China. Central-NE harbours more reworking juvenile...
Several gold ore-concentrated areas have been recognized in the destruction zone of North China Craton (NCC). However, deposits western part received less attention. Miaoan, a typical Au-polymetallic deposit northern Taihang Mountain, provides good sample for deepening our understanding genesis zone. In this study, detailed ore geology, pyrite Rb-Sr age, trace element and S-C-O isotopes Au-bearing ores were conducted to constrain source ore-forming materials their tectonic setting. The...
Abstract The location of a large group maars in basin 200 km2 Huitengxile, Inner Mongolia Autonomous Region China, was probably the center magmatic plume past. cross section looks like saucers, with diameters ranging from largest 900 to smallest 10 m. Crashed rocks strata exposed by drill core and magnetic survey indicate explosions underground insupportableness steam accumulation interaction magma water. In Huitengxile other parts Mongolia, same shape caprock age characteristics exist an...
