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
