He has also served as the minister at Palmerston Place Church in Edinburgh since 1996. Previous studies have highlighted the expected differences in channel dyna... Landslides triggered by the 2015 Gorkha (Nepal) earthquake supply large amounts of sediment to rivers. And by investing in these technologies right from the start, universities in Scotland and shared facilities such as SUERC have established themselves as leaders in various specialist areas in geoscience, making a major contribution to our knowledge of climate change as well as global change. shortening related to the formation of the Outer Carphatians and Profile: Professor Hugh Sinclair Main research interests: > The interaction between surface processes (erosion and sedimentation), mountain building and basin subsidence. Though the nature of the early Himalayan foreland basin system is well established in the central Himalaya range, it lacks analysis in the eastern Yarlung Zangbo suture zone. The nature of coarse sediment in rivers emerging from mountain ranges determines rates of downstream fining, the position of the gravel-sand transition, sediment entrainment thresholds, and channel morphologies. A fresh analysis rebuts this idea, reigniting discussion of a long-standing problem in Earth science. It is characterized by an abrupt reduction in median grain size, from gravel- to sand-size sediment, and by a shift in sand transport mode from wash load–dominated to suspended bed material load. The model is used to study how... Orogenic asymmetry is ubiquitous in terms of topography, structure and metamorphism, but the relative influences of climate and tectonics in determining such asymmetry remain contentious. cooling prior to the onset of forearc sedimentation in the region (42-39 Ma). This generates the localization of deformation across persistent structures as emergent phenomena unlike many continuum models that require predefined weaknesses to localize strain. Twenty-five years ago, for example, we knew a lot less about the growth and denudation of mountains because we had so little knowledge of the rates of erosion, including the long - and short-term effects of climate change. However, a synthesis of data from numerous foreland basins recognizes a wide range of signals and rates. Western Carpathians) by the application of low temperature thermochronology. Here we use a modeling approach to analy... ABSTRACT40Ar–39Ar dating of detrital white micas, petrography and heavy mineral analysis and whole-rock geochemistry has been applied to three time-equivalent sections through the Siwalik Group molasse in SW Nepal [Tinau Khola section (12–6 Ma), Surai Khola section (12–1 Ma) and Karnali section (16–5 Ma)]. Because the Earth gets hotter as you go deeper (at about 30°C per kilometre), mineral systems with different closure temperatures can record the cooling of rocks during their journey to the surface of the Earth as the overlying rocks are eroded away. Neogene exhumation of the Northern Carpathians revealed by low temperature thermochronology. Bias and error in modelling thermochronology data: A comment on Willett et al. However, despite the... Alpine-type mountain belts formed by continental collision are characterised by a strong cross-sectional asymmetry driven by the dominant under-thrusting of one plate beneath the other. For example, by analysing cosmogenic nuclides – rare isotopes created when high-energy cosmic rays interact with the atoms in rocks, as if they are giving the atoms a suntan – scientists in Edinburgh have discovered that the rocks we now see sitting on the surface of a valley in Antarctica have been there for over eight million years, compared to similar features elsewhere which have only been exposed to cosmic rays since the end of the last ice age, about 18,000 years ago. “The new technologies allow us to progress from making educated guesses to more precise models of elevation and mountain shape through time,” says Sinclair.
