Paleomagnetism of Middle Triassic Lavas From Northern Qiangtang (Tibet): Constraints on the Closure of the Paleo‐Tethys Ocean

We present results from a paleomagnetic study of Middle Triassic lavas ( ~ 242–240 Ma) from the northern Qiangtang block to improve our understanding of the timing and kinematics of the closure of the eastern Paleo‐Tethys Ocean. Characteristic remanent magnetization directions carried by magnetite and hematite formed during high‐temperature oxidation during initial cooling of the lavas are successfully isolated by progressive thermal and...
