“…further suggested that the Late Triassic-Late Jurassic collision between the southern Kunlun and Northern Qiangtang active margins possibly generated a collisional complex including two forearc basins and their accretionary complexes. This kind of collision is typical in accretionary orogens, which can be found in modern examples like the Molucca Sea (Hall, 2002) and their ancient counterparts such as Inner Mongolia (Xiao et al, 2003), the Kelameili suture between the Northern Tianshan arcs and the East Junggar arcs (Xiao et al, 2004), and the Mongol-Okhotsk suture (Tomurtogoo et al, 2005). Therefore, we suggest that the northern Hohxil high-Mg andesites and dacite suites, occurring just south of the Anyimaqen-Kunlun-Muztagh suture, were most likely generated in a forearc setting (Fig.…”

“…The Bogda orogenic belt is situated between the Juggur and the Turpan-Hami Precambrian terranes ( Fig. 1b) with sub-E-W trending direction, and is interpreted to be a late Paleozoic rift (He et al, 1995;Han et al, 1999;Gu et al, 2001a), arc Coleman, 1989) or an intra-arc basin (Xiao et al, 2004) by different authors. Further to the northeast, the Kelameili-Harlik orogenic belt is characterised by Devonian-Carboniferous arc volcanic rocks (He et al, 1995;Ma et al, 1997;Gu et al, 1999).…”

New Sr-Nd-O isotopic data are reported for the early Triassic (early Indosinian) Weiya quartz syenite from eastern Central Tianshan, northwestern China, with the aim of documenting its possible source(s), constraining its petrogenesis and discussing its tectonic implications. Whole-rock Rb-Sr isochron of the Weiya quartz syenite rock yielded an age of 246.5 ± 4.8 Ma, which is well consistent with zircon SHRIMP U-Pb age. Additionally, the rock exhibits positive ε Nd (t) value (+1.36 to +1.66), medium I sr (0.7088 to 0.7090), "normal" δ 18 O value (6.9 to 8.1‰) and young Nd model ages (T DM = 0.88 to 0.91 Ga). Combined with their petrogaphic and geochemical characters, the Weiya quartz syenite is suggested to have been generated by partial melting of juvenile lower crust rocks at high temperature. The partial melting is attributed to intra-continental subduction, which resulted in thickening of the continental crust, delamination of the lithosphere root, underplating of mantle-derived magma and subsequent regional extension. Heat from underplated mantle magma caused melting of the overlying lower crustal rocks and consequent generattion of the quartz syenitic liquid. It is supposed that the intra-continental subduction was induced by tectonic conversion from the Paleo-Asian subduction-collision system to the Paleo-Thethys regime during the latest Permian or earliest Triassic in the eastern Tianshan.

“…Note that various schemes are used to down-regulate ε in different light-use efficiency-based GPP models [26,[28][29][30]. We compared most schemes and their combinations to yield the solution used in this study, which has a relatively high accuracy and is convenient for use at the regional scale [31].…”

Abstract:The modeling and partitioning of regional evapotranspiration (ET) are key issues in global hydrological and ecological research. We incorporated a stomatal conductance model and a light-use efficiency-based gross primary productivity (GPP) model into the Shuttleworth-Wallace model to develop a simplified carbon-water coupling model, SWH, for estimating ET using meteorological and remote sensing data. To enable regional application of the SWH model, we optimized key parameters with measurements from global eddy covariance (EC) tower sites. In addition, we estimated soil water content with the principle of the bucket system. The model prediction of ET agreed well with the estimates obtained with the EC measurements, with an average R 2 of 0.77 and a root mean square error of 0.72 mm·day −1 . The model performance was generally better for woody ecosystems than herbaceous ecosystems. Finally, the spatial patterns of ET and relevant model outputs (i.e., GPP, water-use efficiency and the ratio of soil water evaporation to ET) in China with the model simulations were assessed.
