“…On the contrary, the Sibumasu Terrane was subjected to CCW rotation by 15° (Yamashita et al, 2011). Although, the sense of rotation in this terrane is similar to that observed in South Sundaland Block, the amount of rotation in the former is much smaller than that in the latter.…”

“…The same sense deflection of more than 30°is widely observed in the Indochina Block as well. However, the paleomagnetic directions from South Sundaland are characterized by counterclockwise (CCW) deflected declinations (Yamashita et al, 2011). A similar trend of declinations (D = 270-320°) has also been observed in the Jurassic to lower Miocene rocks of Peninsular Malaysia, Borneo, southern Sulawesi and Celebes Sea.…”

“…1) is counted as a part of the Sibumasu Terrane, because they remained united as a single tectonic unit until Early Jurassic time. A westerly deflected declination (D = 342.8°), reported by Yamashita et al (2011) from secondary remanent magnetization of the west Trang locality (Peninsular Thailand), is taken into consideration here. Although, its timing is still obscure, up to 15°CCW rotation is predicted for the Sibumasu Terrane in this model.…”

“…The observed Jurassic declinations from Indochina and Sukhothai terranes (with positive fold test results) are indicated by orange color arrows, while those from Sibumasu Terrane are indicated by black color arrows. The red color arrows show declinations of the secondary remanent magnetization from West Trang area in Thailand (Yamashita et al, 2011).

“…Trace amounts of goethite have been detected by thermal demagnetization of the composite IRMs in remagnetized Jurassic to Cretaceous red beds (Tsuchiyama et al, ; Yamashita et al, ). We realize, however, that most goethite grains in remagnetized red beds are possibly nanoscaled and can be detected by low‐temperature experiments at best.…”

Red beds are well‐known for recording stable natural remanent magnetization (NRM). However, discriminating primary NRM from secondary remanence in red beds is difficult. The Paleogene Nangqian red beds in eastern Tibetan Plateau variably record an overprint related to nearby magmatism and thus provide a great opportunity to characterize remagnetization in red beds. Through comprehensive rock magnetic, Mössbauer spectroscopic, and petrographic analyses, we find that remagnetization was controlled by temperature. Remagnetized red beds contain abundant authigenic hematite and goethite, with some larger grains unblocking at the Néel temperatures and the remainder (nanoparticles) unblocking at lower temperatures. In contrast, red beds retaining primary NRM are characterized by dominance of detrital hematite and magnetite, presence of fine‐grained authigenic hematite, and absence of authigenic goethite and magnetite. High temperature behaviors of NRM/susceptibility are indicative of remagnetization, but the presence of goethite appears to be a more sensitive criterion for diagnosing remagnetization in red beds.

A palaeomagnetic study of the Middle Permian and Middle Triassic limestones from Shan State, Myanmar: Implications for collision of the Sibumasu Terrane and Indochina Terrane

We report herein a new palaeomagnetic study on the Middle Permian and Middle Triassic limestones from Shan State of eastern Myanmar, aiming to resolve the spatial location of the Sibumasu Terrane during the collision of tectonic blocks in Southeast Asia and to constrain the timing of convergence between the Sibumasu Terrane and Indochina Terrane. Based on the rock magnetic and palaeomagnetic experiments, three stable characteristic remnant magnetizations are recognized from limestone specimens of Middle Permian and Middle Triassic age. The characteristic Component C of the Middle Permian limestone passed the fold test at 95% confidence level, indicative of a pre‐folding origin. The mean direction of this component is D = 10.7°, I = 17.9° (κ = 130.3, α95 = 10.8°) before and D = 13.7°, I = −25.3° (κ = 1894.9, α95 = 2.8°) after tilt correction, corresponding to a palaeomagnetic pole at 254.1°E, 53.2°N (A95 = 1.7°). This suggests that the Sibumasu Terrane was placed at a palaeolatitude of ~13.0°S during the Middle Permian. The Component C separated from the Middle Triassic samples also passed the fold test with a mean direction of D = 207.3°, I = −8.3° (κ = 12.9, α95 = 6.2°) before tilt correction and D = 205.6°, I = −33.5° (κ = 27.1, α95 = 4.2°) after tilt correction, corresponding to a palaeomagnetic pole at 187.3°E, 65.8°N (dp/dm = 2.7°/4.8°). This implies that the Sibumasu Terrane was located at a palaeolatitude of ~18.3°N during the Middle Triassic. Based upon the detailed palaeomagnetic analysis, this study supports the view that the collision of the Sibumasu Terrane and Indochina Terrance occurred during or before the Middle–Late Triassic times.
