A polyorogenic model for the Paleoproterozoic Trans-North China Belt: Insights from an integrated structural, metamorphic and geochronological study.
Abstract
In the North China Craton, the Paleoproterozoic Trans-North China Belt (TNCB) is a nearly north-south trending zone, of 1200 km long and 300 km wide, that separates two Archean blocks. Previous tectonic models assumed that the TNCB is the result of a 1850 Ma collision between the two Archean eastern and western blocks with an intervening 2500 Ma magmatic arc.
