Abstract The Mongolia Block (MOB), which is now sandwiched by the Siberia Craton (SIB) and North China (NCC), plays an essential role for understanding late stage evolution of Paleo‐Asian Ocean early Mongol‐Okhotsk Ocean. Here, a paleomagnetic study performed first time on Early Permian volcanic strata in Bayandun region northeastern data are used to uncover Paleozoic paleoposition MOB better understand both oceans. Zircon U‐Pb dating results reveal emplacement age 283 ± 3 Ma studied strata....
Abstract To better constrain the evolution of Mongol‐Okhotsk suture, we carried out new paleomagnetic studies on Sharilyn Formation (~155 Ma) and Tsagantsav (~130 in southern Mongolia, Amuria Block (AMU), Tuchengzi (~140 Dadianzi/Yixian Yanshan belt, North China (NCB). A total 719 collected samples (from 100 sites) were subjected to stepwise thermal demagnetization. After a low‐temperature component viscous magnetic remanence acquired recent field was removed, stable high‐temperature...
Abstract The timing of formation the Hegenshan suture is crucial to understanding evolution Central Asian Orogenic Belt (CAOB). Here we present a well‐dated paleomagnetic pole (103 samples from 15 sites, 36.7°N/29.2°E, A 95 = 3.3°) that passed positive fold test, reversal and conglomerate test ∼250 Ma upper Gunbayn Formation andesites in southeastern Mongolia Block (MOB). high‐quality database may demonstrate MOB drifted rapidly southward collided with Xilinhot–Songliao between 256 250 Ma,...
Abstract The Mongolian Altai Zone of the Central Asian Orogenic Belt has been traditionally interpreted as a mosaic Paleozoic magmatic arcs, back‐arcs, and Precambrian continental terranes. In order to define its architecture tectonic evolution, three domains previously terranes were investigated. findings show that Northern are formed by metamorphic sequence characterized Barrovian S1 fabric transposed recumbent folds dominant sub‐horizontal amphibolite facies S2 schistosity. latter is...
Abstract In the Altai Accretionary Wedge, several periods of Barrovian‐ and Buchan‐type metamorphic cycles were dated from Ordovician to Permian. However, timing link between these are not clear, their causes debated. order contribute understanding evolution accretionary wedges, we studied an area composed three parallel belts in easternmost extremity Hovd domain located Mongolian Zone: garnet gneiss north, garnet–staurolite–kyanite schist overprinted by...
The Amuria block occupies the eastern part of Central Asian Orogenic Belt between Siberia craton and North China (NCB) bears important information to understand evolution MongolOkhotsk suture amalgamation East Asia. However, paleomagnetic database remains very poor.
<p>The Mongolian Altai Zone is a part of the extensive Cambrian–Ordovician accretionary system located at junction Siberian craton to north and Tarim North China cratons south. It extends approximately 2,000 km from Russia Mongolia represents one critical elements for reconstructing early Paleozoic geodynamics Central Asian Orogenic Belt (CAOB). The studied section comprises succession deformed low- high-grade metasedimentary rocks characterised by dominant...
