Geometric, kinematic, and erosional history of the central Andean Plateau, Bolivia (15–17 S)
[1] Latitudinal changes in topography, climate, and thrust belt geometry in the central Andes have led to conflicting hypotheses that climate or tectonics exert a first-order control on orogen evolution. The relative roles of climate and tectonics in the evolution of the Andean orogen are difficult to quantify because of a lack of detailed observations for both the long-term deformation and ero...
متن کاملEocene to recent variations in erosion across the central Andean fold- thrust belt, northern Bolivia: Implications for plateau evolution
Quantifying the erosional and kinematic evolution of orogenic plateaus has been limited by insufficient age constraints on their deformation and erosion histories. Palinspastic restorations suggest the central Andean fold-thrust belt and plateau evolved concurrently in Bolivia. We present an analysis that synthesizes 19 new and 32 previous apatite and zircon fission-track and (U–Th)/He mineral ...
متن کاملIncision into the eastern Andean Plateau during Pliocene cooling.
Canyon incision into mountain topography is commonly used as a proxy for surface uplift driven by tectonic or geodynamic processes, but climatic changes can also instigate incision. The ~1250-kilometer (km)-long eastern margin of the Andean Plateau hosts a series of 1.5- to 2.5-km-deep canyons that cross major deformation zones. Using (U-Th)/He thermochronology, we document a transition from Mi...
متن کاملIce core precipitation record in central Tibetan plateau since AD 1600
Lack of reliable long-term precipitation record from northern Tibetan Plateau has constrained the understanding of precipitation variation in this region. An ice core drilled from the Puruogangri Ice Field on central Tibetan Plateau in the year 2000 helped reveal the precipitation variations since AD 1600. Analysis of the annual accumulation 5 data presented precipitation changes from AD 1600, ...
متن کاملVegetation-precipitation controls on Central Andean topography
Climatic controls on fluvial landscapes are commonly characterized in terms of mean annual precipitation. However, physical erosion processes are driven by extreme events and are therefore more directly related to the intensity, duration, and frequency of individual rainfall events. Climate also influences erosional processes indirectly by controlling vegetation. In this study, we explore how i...
