| 摘 要： | <正>Objective The tectonic characteristics and evolution of the Paleoproterozoic Jiao-Liao-Ji belt have been extensively studied in recent decades(Fig.1 a).Two main models have been proposed for the formation of this belt:a continental-or arc-continent collisional belt,and the opening and closure of an intra-continental rift.The main reasons for these ongoing debates are own to the complex composition,including metamorphosed volcano-sedimentary rocks,multiple pulses of granitic magmatism,meta-mafic intrusions,and tectonometamorphic history.In addition,earlier work focused on the geochronology and metamorphic evolution,whereas the
