Onset timing of significant unroofing around Qaidam basin, northern Tibet, China: constraints from 40Ar/39Ar and FT thermochronology on granitoids

Detrital apatite fission track evidence for provenance change in the Subei Basin and implications for the tectonic uplift of the Danghe Nan Shan (NW China) since the mid-Miocene

“…2(h)). Bedrock and detrital apatite fission track and (U-Th)/He thermochronologic data have provided new constraints on the deformation history of northern Qaidam Basin focused in the middle Miocene (Wang et al, 2004;Zhuang et al, 2009) (Fig. 2A-(d)-(e)).…”

The original map is modified from Bovet et al (2009) From detailed field mapping, Wang (1997) suggested that the displacement of the Subei Basin by the ATF was largely in the mid-Miocene to Recent.…”

Differential growth of the northern Tibetan margin: evidence for oblique stepwise rise of the Tibetan Plateau

“…2), the Kunlun Belt is considered, from a tectonic perspective, to be a part of the Paleozoic-Triassic collision belt and was rejuvenated during the Cenozoic Eurasia–Indian collision and the growth of Tibetan Plateau1123. A few low-temperature thermochronological studies have been reported from the eastern part of the Kunlun Belt521242526, where a cooling history between 350–60 °C was extracted. A rapid exhumation event and therefore the onset of deformation during the Cenozoic were then concluded to have occurred at approximately 30 Ma2425 or 40 Ma510 in the eastern part of the Kunlun Belt.…”

In contrast, low temperature geochronological studies are lacking, and existing constraints on the exhumation and cooling history of the western part of the Kunlun Belt are very poor.…”

Continental dynamics in a multi-convergent regime: a receiver function study from the North–South-Trending Tectonic Zone of China

“…The rise of the Tibetan Plateau occurred progressively from south to north, with the resultant crustal thickening accommodated by shortening along the compressional direction (Tapponnier et al 2001;Pan and Niu 2011). The collision also resulted in crustal thickening and shortening in the Songpan-Ganzi, Qaidam, Qilian, and Alashan blocks as well as the E-W extrusion (Métivier et al 1998;Meyer et al 1998;Chen et al 1999;Tapponnier et al 2001;Wang et al 2004Wang et al , 2011Cunningham 2013;Zhao et al 2013). Furthermore, studies have also indicated that the Qilian, Qaidam, and Songpan-Ganzi blocks might have extruded from the North and South China blocks during the late Palaeozoic (Yin and Nie 1996;Zhang 1997Zhang , 2002.…”
