The Alashan Terrane did not amalgamate with North China block by the Late Permian: Evidence from Carboniferous and Permian paleomagnetic results

Paleo-position of the North China craton within the supercontinent Columbia: Constraints from new paleomagnetic results

“…In total, there are four contact baked tests to support a primary ChRM in the Yinshan area. Although pointed out in Halls et al (2000), the results from these dykes overlaps with a reported Paleozoic pole from the Alashan terrane of the NCC (Zhao et al, 1993), the later was considered from an allochthonous terrane that amalgamated to the NCC by the late Triassic (Yuan and Yang, 2014). The data from sixteen Table 2 Paleomagnetic results from the Yinshan area.…”

Phanerozoic amalgamation of the Alxa Block and North China Craton: Evidence from Paleozoic granitoids, U–Pb geochronology and Sr–Nd–Pb–Hf–O isotope geochemistry

“…Based on the palaeomagnetic data, the timing is suggested to be in Late Cambrian (Huang et al, 1999(Huang et al, , 2000 or Triassic (Yuan and Yang, 2015b). As pointed by J.…”

Superposed deformation in the Helanshan Structural Belt: Implications for Mesozoic intracontinental deformation of the North China Plate

“…The Helanshan Structural Belt is situated between the Alxa Block and the Ordos Block, and is characterized by a regional-scale Jurassic NE-trending synclinorium, likely related to subduction of the Paleo-Pacific Plate. However, the most recent paleomagnetic study in the Alxa Block suggests that the NNE-trending Helanshan Structural Belt developed in the Late Triassic-Early Jurassic as a result of anticlockwise rotation of the Alxa Block toward the Ordos Block (Yuan and Yang, 2015). These studies show that the deformation processes in the Helanshan Structural Belt are highly controversial, particularly the timing and driving mechanisms of the deformation.…”
