The late Mesozoic closure of the Mongol‐Okhotsk Ocean (MOO) is critical for understanding the tectonics of East Asia. There is a considerable mismatch (~40 million years) between the timing of MOO closure based on paleomagnetic data and geological evidence. We review paleomagnetic data from Mongolia, Siberia, and North China and argue that previously published apparent polar wander paths (APWPs) for North China and Siberia are insufficient to constrain the timing of MOO closure. Our new… 
An Inclination Shallowing‐Corrected Early Triassic Paleomagnetic Pole for the North China Craton: Implication for the Mesozoic Geography of Proto‐Asia
The Early Mesozoic is a key period for the formation of the Asia continent. In this study, in order to reconstruct the Early Mesozoic paleogeography of Proto‐Asia, we carried out a paleomagnetic
Yanshanian Orogeny During North China's Drifting Away From the Trench: Implications of Numerical Models
Tectonics in North China and adjacent areas were dominated by the Pacific Plate subduction since the Jurassic. Although the extension‐dominated tectonics in North China since the Early Cretaceous can
Large-scale Late Triassic to Early Jurassic high εHf(t)–εNd(t) felsic rocks in the Ergun Massif (NE China): implications for southward subduction of the Mongol–Okhotsk oceanic slab and lateral crustal growth
The Manzhouli–Xin Barag right banner are located in the southwest of the Ergun Massif (NE China), the tectonic evolution of these areas are still controversial. In this study, a series of rocks
The Age of Gold Mineralization of the Elga Deposit, Mongol–Okhotsk Fold Belt: 40Ar/39Ar Geochronological Constraints
Abstract As a result 40 Ar/ 39 Ar geochronological studies, the age of gold mineralization has been determined for the Elga deposit that is located in the eastern part of the Mongol–Okhotsk fold


Latest Jurassic–earliest Cretaceous closure of the Mongol-Okhotsk Ocean: A paleomagnetic and seismological-tomographic analysis
The Mongol-Okhotsk Ocean closed when the Amuria block, normally considered to have been part of the North China block since the early Mesozoic, and the southern margin of Siberia collided in Late
Early to Middle Jurassic history of the southern Siberian continent (Transbaikalia) recorded in sediments of the Siberian Craton: Sm-Nd and U-Pb provenance study
The deposition of Jurassic continental sedimentary rocks in the southern part of the Siberian continent (Transbaikalia) reflects the intensification of tectonomagmatic processes in this region. The
Late Jurassic - Early Cretaceous paleoenvironmental evolution of the Transbaikal basins (SE Siberia): implications for the Mongol-Okhotsk orogeny
The Late Jurassic - Early Cretaceous tectonic evolution of SE Siberia was marked by the closure of the Mongol-Okhotsk ocean. While this geodynamic event led to compressive deformation and denudation
Timing of the North-South China collision from new middle to late Mesozoic paleomagnetic data from the
We collected paleomagnetic samples from 43 sites of Middle and Upper Jurassic and Cretaceous rocks along a 250 km wide east-west trending belt located north of the suture between the North and South
New Late Jurassic to Early Cretaceous Paleomagnetic Results From North China and Southern Mongolia and Their Implications for the Evolution of the Mongol‐Okhotsk Suture
To better constrain the evolution of the Mongol‐Okhotsk suture, we carried out new paleomagnetic studies on Sharilyn Formation (~155 Ma) and Tsagantsav Formation (~130 Ma) in southern Mongolia,
