“…Constraints on temperature-time history and possible cooling paths for (A) the deepest exposed levels of the Hsüehshan range where quartzites 148d and 148j were sampled, and (B) the cooler region to the west where the remainder of samples were collected. Cooling rates since ∼3 Ma are well constrained at ∼90 • Myr −1 by zircon fission track (Liu et al, 2001), zircon U-Th-He , and white mica K-Ar data (Tsao, 1996). Note that the x-axis is compressed by a factor of 10 between 30 and 8 Ma.…”

Abstract. The accuracy, reliability and best practises of Tiin-quartz thermobarometry (TitaniQ) in greenschist facies rocks have not been established. To address these issues, we measured Ti concentrations in rutile-bearing samples of moderately deformed, partially recrystallized quartzite and vein quartz from the Hsüehshan range, Taiwan. The spread of Ti concentrations of recrystallized grains in quartzite correlates with recrystallized grain size. Recrystallized quartz (grain size ∼100-200 µm) that formed during early deformation within the biotite stability field shows a marked increase in intermediate Ti-concentration grains (∼1-10 ppm) relative to detrital porphyroclasts (Ti ∼0.1-200 ppm). Fine recrystallized quartz (∼5 % of the samples by area, grain size ∼10-20 µm) has a further restricted Ti concentration peaking at 0.8-2 ppm. This trend suggests equilibration of Ti in recrystallized quartz with a matrix phase during deformation and cooling. Unlike previously documented examples, Ti concentration in the quartzite is inversely correlated with blue cathodoluminescence. Deformation was associated with a minimum grain boundary diffusivity of Ti on the order of 10 −22 m 2 s −1 . Vein emplacement and quartzite recrystallization are independently shown to have occurred at 250-350 • C and 300-410 • C, respectively, with lithostatic pressure of 3-4 kbar (assuming a geothermal gradient of 25 • km −1 ), and with hydrostatic fluid pressure. Estimates of the accuracy of TitaniQ at these conditions depend on whether lithostatic or fluid pressure is used in the TitaniQ calibration. Using lithostatic pressure and these temperatures, the calibration yields Ti concentrations within error of concentrations measured by SIMS. If fluid pressure is instead used, predicted temperatures are ∼30-40 • C too low. TitaniQ has potential to yield accurate PT information for vein emplacement and dynamic recrystallization of quartz at temperatures as low as ∼250 • C, however clarification of the relevant pressure term and further tests in rutile-present rocks are warranted.

“…Erosion is often asymmetric and for our models we use a generic scheme that seeks to mimic the asymmetric exhumation of many two-sided orogens, such as the Southern Alps of New Zealand [Hicks et al, 1996;Hovius et al, 1997], central Taiwan [Liu et al, 2001;Galewsky et al, 2006;Fuller et al, 2006], the St Elias Mountains [Sheaf et al, 2003;Spotila et al, 2004], and the Andes [Masek et al, 1994;Ege et al, 2007;Safran et al, 2006].…”

Three‐dimensional numerical models with varied material properties and erosion rates: Implications for the mechanics and kinematics of compressive wedges

[1] We develop three-dimensional mechanical models of a compressive wedge and investigate how the form and kinematics of the outboard wedge are affected by variation in initial topography, material properties, and erosion rate. Inclusion into the wedge of weaker, less dense material affects the form of the wedge, producing a region of steeper average slopes and higher topography while depriving the region further inboard of material. Enhanced erosion has a similar effect. The wedge attempts to replace the eroded material by focusing deformation. The result is a stepped region of lower topography within the outboard of the orogen. We observe that uplift velocities at three points in the orogen vary cyclically from near zero to $3 times the average uplift rate over cycles lasting on the order of 15-200,000 model years. Our models, along with analog models and some well-dated examples from active orogens, suggest that transient accommodation of strain may be common. The cycles observed responded rapidly to changes in the amount of erosion imposed. Our models suggest that orogens may be driven by strong coupling between erosion and strain on temporal scales of 10 4 -10 5 years and spatial scales comparable to the scale of the erosional perturbation. We compare our models to the Puli Embayment of west central Taiwan, a region of anomalous low topography and suggest that it presence may reflect the presence of weaker and more erodible sediments than those present along strike in the orogen.Citation: Upton, P., K.

“…The progressive arc-continent collision and its southward propagation has been extensively studied, numerous tectonic studies and models address the collisional process Chemenda et al, 2001;Dahlen and Barr, 1989;Ernst and Jahn, 1987;Fuller et al, 2006;Liu et al, 2001;Suppe, 1981Suppe, , 1984Wu et al, 1997). The development of the foreland basin as a loading and sedimentation response to the mountain building has also been largely documented (Chen et al, 2001a;Chiang et al, 2004;Covey, 1986;Lin and Watts, 2002;Lin et al, 2003;Simoes and Avouac, 2006;Teng, 1991;Tensi et al, 2006).…”

a b s t r a c tThis work presents sedimentological observations and interpretations on three detailed sections of the Pliocene Yutengping/Ailiaochiao formations, deposited in the early stages of collision in Taiwan. Seven facies associations record paleoenvironments of deposition ranging from nearshore to lower offshore with a strong influence of tidal reworking, even in shelfal sub-tidal environments, and a pro-delta setting characterized by mass-flows. The association of shallow facies of the upper offshore to lower shoreface with pro-delta turbidite facies sourced in the orogen to the east suggests a peculiar setting in which turbidite deposition occurred below wave base but on the shelf, in water depths of probably less than 100 m. This adds to the examples of ''shallow turbidites" increasingly commonly found in foreland basins and challenges the classical view of a ''deep" early underfilled foreland basin. Time series analysis on tidal rhythmites allow us to identify a yearly signal in the form of periodic changes of sand-supply, energy and bioturbation that suggests a marked seasonality possibly affecting precipitation and sediment delivery as well as temperature. The Taiwan foreland basin may also present a potentially high-resolution record in shallow sediments of the early installation of monsoonal circulation patterns in east Asia. We confirm partly the paleogeography during the early stages of collision in Taiwan: the Chinese margin displayed a pronounced non-cylindrical geometry with a large basement promontory to the west in place of the modern Taiwan mountain range. Collision in Taiwan may have happened at once along the whole length of the modern mountain range, instead of progressively from north to south as classically considered.
