“…In contrast, there are only 26% and 39% zircon grains with these U-Pb ages occur in the postorogenic samples QZ08 and KP02. The age spectra of the postorogenic samples show some similarity to those from the Yunkai Domain with several age populations Xu et al (2013Xu et al ( , 2014, Yao et al (2011Yao et al ( , 2014, , Zhou et al (2015), Yan et al (2017), and this study). clustering at 400-440, 700-800, and 900-1,100 Ma (Wan et al, 2010;Wang et al, 2007;Yu et al, 2010).…”

The thick Silurian siliciclastic sedimentary rocks in the Qin‐Fang region contrasting with their absence in surrounding regions have long been an enigma for the early Paleozoic geology of South China. Here we employ detrital zircon U‐Pb geochronology and Lu‐Hf isotope analysis of Cambrian to Devonian samples from the Qin‐Fang and adjacent regions to trace sedimentary provenance and to further constrain its tectonic setting. The similar age spectra of the Cambrian samples from both sides of the Qin‐Fang region imply that they should be derived from a common source(s), arguing against the presence of a Cambrian ocean in the Qin‐Fang region. However, the U‐Pb age patterns of these Cambrian samples, as well as from Silurian and Ordovician sandstones both from within and outside the Qin‐Fang region, differ significantly from those of a middle Devonian sample from the Qin‐Fang region, and Ordovician to upper Triassic samples from the Indochina Block. These results, in conjunction with regional geological information, indicate that the Yunkai Mountain, which is located adjacent to the Qin‐Fang region, must have been emerged above sea level in the middle Devonian. Meanwhile, it can also imply that the Qin‐Fang region should be a part of South China rather than being a segment of the Indochina Block. A two‐stage evolutionary history of the Qin‐Fang region is proposed, (1) an intracontinental basin mainly filled by materials eroded from east Gondwana and/or eastern Cathaysia Block during the early Paleozoic and (2) a foreland basin in the Yunkai Mountain region at least since the middle Devonian.

“…280 Ma; Figures and a), followed by a ~5,000‐km (~47° of latitudinal difference) northward transition until it merged to the southern margin of the Eurasian region in the Indosinian Orogeny Event by the Norian Stage of the Late Triassic (ca. 220 Ma; Figures and b; Yan et al, ). This implies an average northward drift rate of ~9 cm/year relative to the Earth's rotation axis, and ~4.5 cm/year relative to Gondwana, because Gondwana had moved northward by ~23°during the same time interval (ca.…”

“…Based on the prefolding origin of the Permian ChRMs in this study acquired prior to the regional tectonic events including the Indosinian, Middle Cretaceous, and Himalayan Orogeny, it is strongly suggested that this study has recovered a Permian paleo‐field direction. The Permian strata are separated by the Indosinian unconformity from the Mesozoic sediments whose magnetic directions (e.g., Norian age of Late Triassic, Ds/Is = 43.0°/48.0°, α 95 = 6.1°; Early Cretaceous, Ds/Is = 28.6°/39.6°, α 95 = 3.1°) are distinctly different (Yan et al, ), which rules out the possibility of remagnetization. The Stage I of the Indosinian Event corresponds to a considerable hiatus including much of the Upper Permian to Middle Triassic (Ridd et al, ).…”

The drift of Gondwana‐derived blocks across the Tethys has remained unclear specifically because one of the largest components, Indochina, has remained unconstrained by paleomagnetism during the late Paleozoic, the interval comprising the first half of its journey towards the Eurasian landmass. Hence, we report a paleomagnetic study of Early‐Middle Permian limestones from central Thailand yielding a high‐quality data set for the Indochina Block with probable primary origin. The magnetization yields a paleomagnetic pole at 34.1°N, 331.7°E (K = 45.4, A95 = 5.7°) corresponding to a paleolatitude of 21.2 ± 5.7°S at the center of the study area (15°N, 101°E) and supporting a tropical restoration for late Paleozoic Indochina. A total of ~5,000 km northward transition from a proximity to Gondwana in the Early‐Middle Permian (ca. 280 Ma) to the southern margin of Eurasia by the Late Triassic (Norian, ca. 220 Ma) is identified and yields an average northward latitudinal drift rate of ~4.5 cm/year. A concurrent northward drifting history during the Permian is suggested for the Indochina, North Qiangtang, and South China blocks, and thus, the widely used model of Permian Cathaysialand is quantitively supported when combined with their paleobiogeographic affinities.

Paleomagnetic studies on the syncollisional magmatic eruptions provide a direct way to understand when and where the Paleo-Tethys closed. We report a well-dated paleomagnetic pole from the southern Lancangjiang volcanic belt in western Yunnan of China. Stable Characteristic Remanent Magnetizations (ChRMs) were isolated from 21 sites at high temperatures following step-wise thermal demagnetization. The data pass fold, reversal, and conglomerate tests and are interpreted to be primary thermal remanent magnetizations. The new paleomagnetic pole (46.1°N/176.2°E, K=44.9, A 95 =4.8°, N=21) yields a paleolatitude of 26.0 ± 4.8°N at the reference site (23.
