Abstract The tectonic evolution of the Paleo‐Jinshajiang Ocean, and in particular time its closure, is debated. Here we present new constraints on this region from an integrated paleomagnetic geochronologic study Late Triassic Batang Group volcanic rocks Qamdo, Eastern Qiangtang Terrane (EQT). Two zircon U‐Pb ages indicate that erupted at ∼227–222 Ma. New results yield a robust paleopole 57.6°N, 176.4°E ( A 95 = 7.8°), corresponding to paleolatitude 32.5 ± 7.8°N for area. Integrated with...

Abstract Discordant Cenozoic paleomagnetic rotation results obtained throughout the northeastern Tibetan Plateau have yielded different tectonic models for evolution of Altyn Tagh Fault and Plateau. Here based on detailed existing magnetostratigraphic age constraints, we carried out an in‐depth study along Hongliugou section in middle northern Qaidam marginal thrust belt to address rotations this region. A total 1,342 Jurassic‐Neogene siltstone‐sandstone core samples were collected from 128...

β-Adrenergic receptor induces cAMP/Protein kinase A (PKA) activation to regulate cardiac contraction. Using real-time fluorescence resonance energy transfer imaging for highly sensitive detection of cAMP and PKA activities, we show two distinct phases in isoproterenol dose-dependent responses cardiomyocytes: a transient increase activities at lower concentrations from 10<sup>−12</sup> 10<sup>−8</sup> M; saturated initial increases higher 10<sup>−5</sup> M followed by rapid decrease different...

Abstract The clockwise rotation and southeastward extrusion of the southeastern Tibetan Plateau have played important roles in accommodating uplift deformation plateau. Numerous paleomagnetic studies suggested post–late Eocene along eastern Himalaya syntaxis, whereas few researchers addressed specific deformation, leading to ambiguous interpretations tectonic evolution region. Herein, we conducted a study Yunlong Formation Basin, which is Late Cretaceous early Paleocene age. In total, 386...

Abstract The Paleocene‐Eocene Thermal Maximum (PETM, ∼56 Ma), was a transient episode of global warming, and caused profound changes in biology climate. evolution the hydroclimate during PETM East Asia, which currently is influenced by Asian Monsoon hosts ∼20% world's population, crucial to understand future monsoon climate changes. However, records Asia are relatively rare it remains poorly understood how responded forcing under extreme atmosphere p CO 2 . Here we present stable carbon...

Abstract Reconstructing the compressional strain history of northern Qaidam marginal thrust belt has significant implications for understanding mountain building processes northeastern Tibetan Plateau and tectonic evolution Altyn Tagh Fault. However, variation in this region rarely been studied. Here, we present Cenozoic anisotropy low‐field magnetic susceptibility records from fluvial‐lacustrine Hongliugou profile within middle part belt. The fabrics Shizigou Formation are dominated by a...

Abstract The Cretaceous Normal Superchron (CNS), defined as a magnetic quiet zone spanning from ∼126 to ∼84 Myr, is often used understand the Earth’s geodynamo processes. However, whether there were polarity reversals within CNS remains contentious. This paper presents youngest detrital zircon U‐Pb age‐constrained magnetostratigraphic study of Khorat Group for two sections (i.e., Ban Phonngam (BP) and Nongpen (BN)) in Vientiane, Laos. Both are characterized by prominent long normal‐polarity...

SUMMARY A series of terranes were accreted to Eurasia in the region what is now Tibetan Plateau, including Qaidam-Qilian, Songpan-Ganzi, Qiangtang, Lhasa and Tethyan Himalaya terranes. The drift history Qiangtang Terrane timing Lhasa–Qiangtang collision are controversial. To contribute this topic, here, we palaeomagnetically investigate Middle-Upper Jurassic limestones Yanshiping group Zaduo area (32.5°N, 95.2°E), Estern Terrane. Twelve sites (133 samples) processed. major challenge...

Abstract Many recent biomagnetostratigraphic studies within and around the Tibetan Plateau have resulted in significant age differences, due to lack of radiometric constraints. It has hindered knowledge on tectonic paleoclimate evolutions Plateau. Identifying barely visible tephra‐bearing layers is urgent solve debate.
