Paleomagnetic study of late Proterozoic and Early Cambrian rocks in terranes of the Amur plate

Zircon U–Pb ages of the metamorphic supracrustal rocks of the Xinghuadukou Group and granitic complexes in the Argun massif of the northern Great Hinggan Range, NE China, and their tectonic implications

“…800-1000 Ma for detrital zircons obtained in this study imply that the Grenvillian Orogeny occurred in the Argun massif and its adjacent areas, which can be interpreted as a regional response to the global Rodinia supercontinent assembly. Based on the palaeomagnetic, geochronological and geological data from the Siberia craton, Tuva-Mongolia, Argun and Jiamusi massifs, Pisarevsky and Natapov (2003), Bretshtein and Klimova (2007) and Pisarevsky et al (2008) believed that the craton and massifs could represent parts of the Rodinia supercontinent from 1050 and 980 Ma, although no direct contact between the two has been documented.…”

New Paleomagnetic Constraints on the Amalgamation of the Tuva and Mongolia Blocks From Late Carboniferous Andesites in the Mongolia Block

“…Previously published Carboniferous paleomagnetic data for the interior of the MOB are inconsistent, as shown by the significant differences in paleolatitudes (∼21.3°S–52°N; Table 2). Based on the newly “Reliability” index (Meert et al., 2020), we excluded some paleomagnetic data because (a) some paleomagnetic data were obtained for a limited number of samples (<25; Bretshtein & Klimova, 2005), and (b) some data cannot be used to determine the origin of the characteristic remanent magnetization (Chen et al., 1997; Kovalenko, 2010; Kovalenko & Chernov, 2008; Pechersky & Didenko, 1995; Pruner, 1992). There is a high‐quality early Carboniferous ( ca .…”

“…315 Ma paleomagnetic data from Ren et al (2021) to discuss the paleogeographic relationships between the TVB and MOB. For the MOB, some Devonian-Permian paleomagnetic poles were obtained from southern Mongolia (Table 1; Grishin et al, 1991;Kovalenko, 2010;Kovalenko & Chernov, 2008;Pechersky & Didenko, 1995), central Mongolia (Pruner, 1992;Ren et al, 2021), Inner Mongolia (Chen et al, 1997;Li et al, 2012;Zhang et al, 2021;Zhao et al, 2020), and the Upper Amur region (Bretshtein & Klimova, 2005;Kravchinsky et al, 2002). Previously published Carboniferous paleomagnetic data for the interior of the MOB are inconsistent, as shown by the significant differences in paleolatitudes (∼21.3°S-52°N; Table 2).…”
