英文摘要The tectonic background of the Paleoproterozoic Xiong'er volcanic rocks (XVR) is important for understanding the"tectonic evolution of the North China Craton (NCC), as well as its paleogeographic position during the assembly of the Nuna/Columbia supercontinent, Here we report the results of the first anisotropy of magnetic susceptibility (AMS) study of the XVR, and use the interpreted flow directions to constrain the emplacement mechanism and to assess its geological significance for the reconstruction of the Nuna/Columbia supercontinent. Thirty lavas were sampled from three sections in western Henan Province. Detailed rock magnetic analyses, including measurements of hysteresis loops, magnetization versus temperature curves and first order reverse curves, were performed to identify the main magnetic phases and grain sizes. The inferred directions from the AMS results reveal a radial flow pattern with an eruption center probably located near Xiong'er Mountain. Our data suggest that the XVR may have been emplaced in a triple-conjugated continental rift on the south margin of the NCC, probably initiated from a paleoplume. Based on this interpretation, a comparison of geological and paleomagnetic results among the proposed crustal blocks in the Nuna/Columbia supercontinent suggests a close linkage of the NCC with sao Francisco-Congo, Rio de la Plate and Siberia.
