The Central Asian Orogenic Belt (CAOB) is the largest accretionary orogen in world with considerable Phanerozoic juvenile crustal growth. eastern segment of CAOB occupied by NE China and its adjacent areas, which locates a triangle area surrounded Siberian Craton to northwest, North (NCC) south Pacific oceanic plate east. Therefore, key study geological evolution multiple tectonic systems overprinting, has become hot research topic. In past five decades, especially last two there have been...
The tectonic evolutionary history between the Xing'an Block (XB) and Songliao–Xilinhot (SXB) has been hotly debated. Here, we present precise geochronological ages whole‐rock geochemical data in central Great Range for Carboniferous felsic rocks to reveal this history, as petrogenesis of these were closely related activity XB SXB. age with detailed analyses indicate three important stages magmatism: early Carboniferous, Late middle Carboniferous. granodiorites formed from partial melting...
The timing and direction of narrowing closure the Nenjiang Ocean (NJO) by plate subduction remain poorly constrained. This paper presents geochemical, isotopic, geochronological results for Late Devonian to early Carboniferous intrusive rocks in western Songliao–Xilinhot block constrain evolution NJO region. syenogranites monzogranites formed at 366–360 Ma are classified as A‐type granites. wide range ε Hf (t) values (−17.62 +8.13) T DM2 ages (789–2,208 Ma) indicate that primary magma was...
Abstract Two new coniferous wood taxa, Protocedroxylon zhangii sp. nov. and P . zhalantunense nov., are described from the Middle Jurassic Wanbao Formation in Zhalantun City, Inner Mongolia, NE China. The discovery represents first record of petrified Formation, contributes to further understanding floral composition, especially that forest, Formation. Anatomically, two species characterized by having a mixed type radial pitting Abietineentüpfelung. In extant conifers, Abietineentüpfelung is...
The Permian to Triassic period represents a pivotal phase in the evolution of Paleo-Asian Ocean, marked by significant tectonic transitions from subduction, collision, and post-orogenic extension. timing closure Ocean northeastern China has always been controversial. In this contribution, petrology, zircon U-Pb geochronology geochemistry are conducted on granite found well HFD1, Songliao Basin, eastern part Central Asian orogenic belt. Zircon dating indicates that crystallized at 258.9 ± 2.2...
The Zhalantun terrane from the Xing'an massif, northeast China, was used to be considered as Proterozoic basements. However, amounts of detrital zircon ages meta‐sedimentary rocks deny existence Precambrian basements recently. Notably, magmatic were barely reported limit exact In this study, we collected rhyolite, gabbro and quartz diorite for in‐situ U‐Pb isotopic dating, which yield crystallization ∼505 Ma, ∼447 Ma ∼125 respectively. Muscovite schist siltstone define maximum depositional...
Northeast China occupies the majority of eastern Central Asian Orogenic Belt, which mainly consists continental blocks and accretionary terranes. The Devonian was a tectonic quiet period in NE region due to lack tectono-magmatism, but background this has been unclear, especially for Hegenshan-Heihe Suture between Xing’an Songliao terranes, represents Paleozoic Nenjiang Ocean (a branch ocean Paleo-Asian Ocean). Here we report granitic rocks from Woluohe area, Northern Great Range, China,...
