Mafic dyke swarms are excellent time markers and paleostress indicators. Numerous late Paleoproterozoic mafic dykes are exposed throughout the Trans-North China Orogen (TNCO). Most of these dykes trend NW-SE or NNW-SSE, nearly parallel to the orogen, while a series of E-W trending mafic dykes are restricted in the L€ uliang and southern Taihang areas in the central segment of the TNCO. These dykes were mostly considered to be linked with breakup of the supercontinent Columbia previously. In this study, 16 mafic dykes were investigated in the L€ uliang Complex. Zircon LA-ICP-MS dating of four samples yields magmatic crystallization ages of 1.78-1.79 Ga. These dykes belong to the tholeiite series and consist of basalt, basaltic andesite, and andesite. They are enriched in LREE and LILE and depleted in HFSE, and have negative zircon eHf (t) values of 21.7 to 212.2. The E-W trending mafic dykes show similar geochemical and isotopic features compared to the NW-SE trending dykes in other complexes. They were most likely originated from a lithospheric mantle metasomatized by subduction-related fluids and later emplaced along extensional fractures in a postcollisional setting. NW-SE trending fractures were formed due to gravitational collapse and thinning of the lithosphere. E-W trending fractures in the central segment of the orogen constitute a transverse accommodation belt to equilibrate the different amounts of extension between the northern and southern TNCO. The impact of the postorogenic extension might have continued to approximately 1680 Ma as evidenced by the presence of abundant approximately 1750-1680 Ma anorthositegabbro-mangerite-rapakivi granite suites (AMCG-like) occurring in the northern NCC.

“…When continents break apart to form new ocean basins, the rifting process may or may not occur along with contemporaneous igneous activity (White and Mckenzie 1989;Keir et al 2013;Xia et al 2013). Magmatism when present provides fundamental information on the rifting process, such as timing of melt generation, composition and depths of magma sources during evolution of the rift.…”

“…1948 Ma (Figure 9b). Similar ages of 1916 ± 36 Ma (meta-gabbro in the northern Tarim, Deng et al 2008), 1915 ± 36 Ma (Xinger granite in the northern Tarim, Long et al 2012), and many others were previously obtained from igneous rocks in the Quruqtagh area of the northern Tarim Block, which is possibly associated with the assembly of the Columbia supercontinent (Rogers and Santosh 2002;Zhao et al 2002Zhao et al , 2003Zhao et al , 2004Santosh et al 2009a;Long et al 2012;Zhao and Cawood 2012;Carroll et al 2013;Xia et al 2013).…”
