Tectonic and geomorphic controls on the lacustrine deposits of the Neogene Vinchina basin, northwestern Argentina
(Society for Sedimentary Geology, 2020-02-27)
Two episodes of lacustrine sedimentation, separated by an erosional surface and fluvial sedimentation, took place in the southern part of the broken foreland Vinchina basin (NW Argentina) between 11 and 5 Ma. The lacustrine ...
Lacustrine record of last millennia eruptions in Northern Chilean Patagonia (45-47 degrees S)
(2017)
Due to its tectonic setting, the Andean Southern Volcanism Zone (SSVZ) is characterized by frequent volcanic activity. Chilean Patagonia lake sediments represent powerful archives of historical and past eruptions since the ...
Microfossils in micrites from Serra da Bodoquena (MS), Brazil: taxonomy and paleoenvironmental implications
(Academia Brasileira de Ciências, 2012)
Microfossils present in Quaternary micrites from Serra da Bodoquena, Mato Grosso do Sul State, Brazil, are here described for the first time. The studied taxa are: a) ostracods: Candona sp., Candonopsis sp., Cyclocypris ...

Lacustrine turbidites produced by surficial slope sediment remobilization: A mechanism for continuous and sensitive turbidite paleoseismic records
(2017)
Turbidite records along ocean margins and in lake basins are increasingly used as paleoseismic proxies. However, the slope remobilization processes that formed the earthquake-related turbidity currents are poorly understood ...
Fluvio-lacustrine sedimentary processes and landforms on the distal Paraguay fluvial megafan (Brazil)
(2019-10-01)
Tropical fluvio-lacustrine depositional processes along the toe of the Paraguay fluvial megafan were investigated with a focus on Lake Uberaba (LU), the largest lake in the Pantanal wetlands. A limnogeological analysis of ...
