Abstract

The debate about the Amazonia landscape evolution has been highlighted in the last two decades, which the scientific advances agree that biotic and abiotic evolution might be intimately related. The main hypothesis argue that the transcontinental Amazonian fluvial system was established in the late Miocene and its evolution should be strongly influenced by tectonic, sea level and/or climatic oscillations during the Pliocene and Quaternary. However, a detailed reconstruction of the post-late Miocene history of Amazonia is still necessary to solve many geological and geomorphologycal problems, as well as improve the understanding about the response of the biodiversity to long-term environmental changes. This post-doctoral proposal aims to use an integrated approach combining OSL and TCN methods to improve the geochronology of late Cenozoic sedimentary units as well as track changes in the Amazonian fluvial system since the early Pliocene. The expected outcomes will provide new deals about: (1) how modern Amazonian fluvial system responded to late Cenozoic climate changes; (2) the potential integration of OSL and TCN methods to dating long-term depositional events (<5 Ma); (3) how erosion and sedimentation rates change over time in tropical lowlands. The proposed to use multiple geochronological methods in large fluvial systems will be a worldwide pioneer approach. In addition, this project will enable a international exchange between laboratories and researchers, in which we expect a strong scientific and technological development.
