Columbia is considered as the first coherent supercontinent in Earth history, proposed by Rogers and Santosh (2002). The assembly and breakup of the PalaeoMesoproterozoic Columbia supercontinent has been extensively discussed, and shed light on the tectonic settings of major metallic deposits formed during Columbia supercontinent cycle (Kaur and Chaudhri, 2013 and references therein). The North China Craton (NCC), one of the fundamental Precambrian nuclei of Asia, has recently been in focus related to studies on the history of assembly, evolution and breakup of the Paleoproterozoic supercontinent Columbia (Santosh, 2010 and references therein). The NCC is consists of three major Paleoproterozoic tectonic belts: the Khondalite Belt, Trans-North China Orogen and Jiao-Liao-Ji Belt in the western, central and eastern parts of the craton, respectively (Zhao et al, 2005). The eastern Liaoning province is a part of the Jiao-Liao-Ji Belt in the eastern parts of the NCC. Here, we summarize the geochronological data of the Jiao-Liao-Ji Belt and uranium deposits to discuss the tectonic setting of uranium mineralization related to the Paleoproterozoic orogenisis.
