Late 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...
متن کاملLate Cenozoic uplift along the northern Dead Sea transform in Lebanon and Syria
Evidence of long-term, late Cenozoic uplift, as well as strike-slip faulting, is revealed by topographic and geological features along the northern 500 km of the Dead Sea fault system (DSFS) – the transform boundary between the Arabian and African plates in the eastern Mediterranean region. Macro-geomorphic features are studied using a new, high-resolution (20 meter pixel) digital elevation mod...
متن کاملLate Cenozoic moisture history of East Africa.
Lake sediments in 10 Ethiopian, Kenyan, and Tanzanian rift basins suggest that there were three humid periods at 2.7 to 2.5 million years ago (Ma), 1.9 to 1.7 Ma, and 1.1 to 0.9 Ma, superimposed on the longer-term aridification of East Africa. These humid periods correlate with increased aridity in northwest and northeast Africa and with substantial global climate transitions. These episodes co...
متن کاملSpecial Section: Late Cenozoic Fluvial Deposits
Mapping in the Homs region of Syria has revealed a hitherto unrecognized staircase of at least 12 gravel terraces of the upper Orontes River. The terrace gravels overlie Pliocene lacustrine marl and have been calcareously cemented into conglomerates, sometimes interbedded with cemented fine-grained alluvium. A tentative dating scheme, based on modelling the regional-scale surface uplift that ha...
متن کاملConclusion: Reconstructing and Modelling Past Oceans Paleoceanography of the Late Cenozoic (Elsevier) Volume 1: Methods in Late Cenozoic Paleoceanography
The science of reconstructing past climates has evolved rapidly over the past three decades. Having started as a subdiscipline of geology and geochemistry [Imbrie and Imbrie, 1979], it is today an interdisciplinary research field which unifies a large international scientific community. Some of the most innovative and suprising research in this field has important implications for future climat...
