Structural, metamorphic and geochronological works in the Hengshan-Wutaishan-Fuping massifs and correlation with the Lüliang massif: Implication for the tectonic evolution of the Trans-North China Belt

摘要

The Paleoproterozoic Trans-North China Belt is a nearly north-south trending zone, of 1000 km long and 300 km wide, which resulted from collision between two Archean Eastern and Western Blocks, marking the amalgamation of the North China Craton. Field surveys in the best-exposed crustal segment of the Trans-North China Belt, namely Luliangshan, Hengshan, Wutaishan and Fuping massifs, allow us to recognize several tectono-metamorphic units that can be correlated throughout each massif. Structural work helps us to define the bulk geometry and kinematics of the belt.
