“…The Zhongdian arc, which is the southern part of the Yidun arc, contains many Late Triassic intermediate-felsic porphyritic intrusions and associated andesites. The porphyries host porphyry Cu deposits, including the Pulang, Xuejiping, Chundu, and Lannitang deposits (Hou et al, 2004b(Hou et al, , 2007Li et al, 2011;Ren, 2011;Wang et al, 2011;Leng et al, 2012;Chen et al, 2014). In addition, several Late Cretaceous Mo-Cu polymetallic deposits related to the granitic plutons are found in this region, such as in the Xiuwacu, Relin, Hongshan, and Tongchanggou areas Li et al, 2007Li et al, , 2013Meng et al, 2013;H.…”

“…65-15 Ma) (Qu et al, 2003;Hu et al, 2005;Zhao et al, 2007). However, in the Late Triassic, different tectonic frameworks and rock assemblages existed in the northern and southern parts of the Yidun arc, due to differences in the slab subduction angle (steep in the north and shallow in the south; Hou et al, 2004bHou et al, , 2007. Correspondingly, a back-arc basin and bimodal volcanic suites were developed in the northern part (i.e., the Changtai arc), while normal arc magmatic rocks (e.g., andesites and felsic porphyries) and associated porphyry copper deposits (e.g., at Pulang) were developed in the southern part (i.e., the Zhongdian arc).…”

“…Active structures in the TRR (Figure 2) include the Ganzi Fault system (a left-slip strike-slip system in the northern Yangtze watershed), a series of normal faults in the upper Yangtze basin, and Hou et al (2007) some small normal and left-slip faults in the eastern lower-Yangtze (Taylor and Yin 2009). The most active fault in the TRR is the north-striking Ganzi Fault system, which high resolution global position satellite (GPS) data have shown to have significant modern left-slip motion (Taylor and Yin 2009).…”

Abstract:Resulting from the collision of the Eurasian and Indian plates, the Qinghai-Tibetan Plateau is commonly known as the 'roof of the world'. Collectively the Yarlung Tsangpo, Nu, Lancang, Yangtze, Yalong, and Yellow River basins drain the eastern margin of the plateau. In this paper, we utilize Shuttle Radar Topography Mission elevation data to examine morphometric and relief attributes of these basins to reveal insights into tectonic activity and rates of incision. A robust technique using Matlab is proposed to alleviate errors associated with SRTM data in the derivation of river longitudinal profiles. Convex longitudinal profiles are interpreted to be a product of uplift rates that exceed rates of channel incision along the entire margin of the QinghaiTibetan Plateau. Highest relief towards the south reflects extensive fluvial incision. High relief is also prominent along major active faults. Erosion patterns are related to distance from knickpoints. Highest rates of erosion and incision are evident towards the south, with decreasing values towards the north, suggesting a link between tectonic activity and erosion.

Mineralogy, zircon U–Pb–Hf isotopes, and whole‐rock geochemistry of Late Cretaceous–Eocene granites from the Tengchong terrane, western Yunnan, China: Record of the closure of the Neo‐Tethyan Ocean

New data from mineralogy, geochemistry, zircon U–Pb dating, and Hf isotopes have revealed Late Cretaceous to Eocene magmatic intrusions in the Tengchong terrane and constrained the origin, tectonic setting, and characteristics of tin‐bearing and barren granitoids. We divide the studied granitoids into two groups: (a) the Late Cretaceous Zhinaxiang (70 Ma) and Early Paleocene Dazhupeng (65 Ma) S‐type barren granites and (b) the Eocene Lailishan A2‐type tin‐bearing granite (50 Ma). All these granitoids display Si‐ and K‐rich and calc‐alkaline characteristics and have similar chondrite‐normalized rare earth element patterns. However, geochemical differences do exist between the two groups of granites. The Zhinaxiang and Dazhupeng S‐type granites are slightly peraluminous, enriched in large‐ion lithophile elements (e.g., Rb and K), and depleted in high‐field‐strength elements (e.g., Nb, Ta, Zr, and Hf), whereas the Lailishan A2‐type granite has higher TFe2O3, high‐field‐strength element content, and Ga/Al ratios. The geochemical and Hf isotopic data indicate that the granites in this study were generated by partial melting of Paleoproterozoic metasedimentary rocks. Due to the subduction of the Neo‐Tethyan Ocean beneath the Eurasian plate, the Zhinaxiang and Dazhupeng S‐type granites were formed in a thickened‐crustal environment, whereas the Lailishan A2‐type granite was emplaced in a post‐collisional extensional setting attributed to slab break‐off. By comparison between tin‐bearing and barren granites, we propose that the Sn mineralization could be related to relatively high‐temperature and low‐pressure crystallization conditions.
