GEOLOGICAL NOTE Climatic Forcing on Channel Profiles in the Eastern Cordillera of the Coroico Region, Bolivia
Orographic precipitation has a large impact on channel morphology and rock uplift via a positive feedback to erosion. We show that in the Eastern Cordillera of Bolivia, channel concavities reach their highest values where annual precipitation increases in the downstream direction, exceeding 3000 mm. The steepest channels are upstream of this zone of high concavity, where precipitation rates are...

Revised deformation history of the central Andes: Inferences from Cenozoic foredeep and intermontane basins of the Eastern Cordillera, Bolivia
[1] Investigation of Cenozoic deformation, sediment accumulation, and provenance in the Eastern Cordillera of Bolivia at 17–21 S indicates major shortening (60–140 km) and foredeep development followed by limited internal shortening and intermontane basin development. Contrasting histories of shortening, deposition, sediment dispersal, and detrital composition distinguish a formerly extensive P...
متن کاملLate Cenozoic uplift of the Eastern Cordillera, Bolivian Andes
This paper analyses Late Cenozoic uplift in the Bolivian Andes, using the morphology of well preserved regional paleosurfaces in the Eastern Cordillera that define three axially draining braided river catchments that formed between ∼12 and ∼9 Ma. Rock uplift since the formation of the paleodrainage systems, which has been quantified using four different methods, is 1705±695 m, with a mean erosi...
