New paleomagnetic results from the ca. 1.68–1.63 Ga mafic dyke swarms in Western Shandong Province, Eastern China: Implications for the reconstruction of the Columbia supercontinent

•We investigated Mesoproterozoic mafic dyke swarms (ca. 1.68–1.63 Ga) in Western Shandong Province by paleomagnetism and rock magnetism.•For ~1.63 Ga mafic dykes, the high-quantity paleomagnetic pole was at 20.8°N, 182.5°E (κ = 28.3, A95 = 8.3°, N = 9) and this pole fulfills a Van der Voo value Q = 6.•For ~1.68 Ga mafic dykes, the corresponding paleomagnetic pole was at 17.8°N, 184.9°E (κ = 29.6, A95 = 14.3°, N = 5).•We finally selected ~1.63 Ga high-quantity paleomagneitc pole for the reconstruction of the Columbia and our reconstruction scenario supports the spatio-temporal connection between Baltica, North Australian Craton and North China Craton.
