“…Inverse modelling results (Figure 6) show that moderate cooling episodes (~0.9–2.1 ℃/Ma) commenced at ~140–100 Ma. Moreover, in the QC (Zhao et al., 2017), southern QT (Figure 5; Zhang et al., 2019) and the Yidun Arc in the south‐eastern Tibet (Tian, Kohn, Gleadow, & Hu, 2014), Early Cretaceous cooling events are documented as well. Two possible interpretations account for this cooling episode.…”

“…It is approximately 500–600 km wide with a >500‐km‐long Qiangtang Culmination (QC) (Figure 1b) (Kapp et al., 2000, 2003). The widespread Mesozoic strata have been deposited in a foreland and hinterland basin (Zhang et al., 2019). Late Cretaceous and Cenozoic terrestrial red beds and volcanics lie unconformably on the sediments stated above (Chung et al., 2005; Ding, Kapp, Zhong, & Deng, 2003; Kapp et al., 2005).…”

The growth of central Tibet remains elusory, albeit important in evaluating different topographic growth models accounting for the Tibetan Plateau development. Thermochronological records in the northern Qiangtang terrane (QT) provide valuable information for investigating the cooling and exhumation history in central Tibet. New apatite fission track data, assisted by inverse thermal modelling, reveal two stages of accelerated cooling. The Early Cretaceous cooling is related with refrigeration of the QT and exhumation probably induced by crustal shortening. The Eocene‐Oligocene renewed cooling reflects the far‐field contraction after the onset of the India‐Asia collision and Cenozoic crustal shortening deformation in the QT, coupled with thermal relaxation and transient lithospheric removal. Our data support models indicating that Cretaceous crustal shortening produced a thickened crust in the QT, whereas the present‐day elevation was established during Eocene‐Oligocene due to crustal shortening, continental subduction and lithospheric delamination.

“…The deformation recorded in Singapore suggests strongly that the last stages of closure of Palaeo-Tethys and the consolidation of Sundaland must also have straddled the Triassic/Jurassic boundary (cf. Carter et al, 2001;Hutchison and Tan, 2009;Metcalfe, 2017;Zhang et al, 2019),…”

Ductile and brittle deformation in Singapore: A record of Mesozoic orogeny and amalgamation in Sundaland, and of post-orogenic faulting

Singapore bedrock geology is dominated by late Permian to Triassic arc magmatism and a genetically related, essentially Middle to Upper Triassic, marine to fluvial volcano-sedimentary inner forearc succession. These Mesozoic strata are deformed into a pattern of NE-translated ductile-brittle deformation structures during the latest Triassic to earliest Jurassic collision and amalgamation of the Sibumasu continental block with the southern part of the Sukhothai Arc. The subduction-related magmatic complex represented in Singapore by the granitic to gabbroic plutons of the Bukit Timah Centre likely acted as a backstop to thrusting at this time. Collisional tectonics drove progressive shortening and steepened earlier-formed inclined asymmetrical folds, culminating in the regional-scale development of a non-coaxial, NE-vergent and NE-facing, fold and thrust system. In Singapore, the Murai Thrust and Pasir Laba Thrust are identified as major elements of this system; both are associated with SW-dipping thrust-imbricate duplex slices. Two distinct early Cretaceous (Berriasian and Barremian) sedimentary successions overstep these collisional tectonic structures. An array of mostly NE-SW and ENE-WSW trending faults and fractures acts as important control on bedrock unit distribution across Singapore and are most likely generated by Cenomanian dextral shear stress. That stress locally reactivated faults initiated during orogeny, or even earlier. Knowledge of the geotechnical impact of these structural features is critical to both future development and ongoing management of the subsurface in Singapore.

The Central Tibetan Mountain Range (CTMR) exposes the oldest strata in the Qiangtang Terrane and may record the most complete exhumation history prior to and post‐collision of India and Asia. This article presents apatite and zircon (U–Th)/He thermochronology data of granites from the CTMR. Zircon (U–Th)/He single grain ages range from 116 to 191 Ma, while apatite (U–Th)/He single grain ages vary from 54 to 94 Ma. Thermal modelling results based on (U–Th)/He ages of apatite and zircon indicate that episodic rapid exhumations occurred at the Middle‐Late Jurassic and the Late Cretaceous, respectively. The Middle‐Late Jurassic exhumation is consistent with the provenance analysis of Jurassic strata in the South (SQT) and North Qiangtang Terrane (NQT) which suggested they were derived from the CTMR. This stage of rapid exhumation might be attributed to the northward ridge subduction of the Bangong‐Nujiang Ocean. The Late Cretaceous relatively rapid exhumation is compatible with the angular unconformity between the Abushan Formation and the underlying marine strata. This stage of exhumation may be caused by the collision between Lhasa and QT. Our results, combined with the crust shortening and adakitic rocks in the SQT during the Late Cretaceous, provide robust evidence for crustal thickening and early uplift of central Tibetan Plateau prior to the India‐Asia collision. The CTMR experienced very low exhumation since the early Eocene, implying that low‐relief topography had been established at high elevation with internal drainage prior to India‐Asia collision.
