Seismites: origin, criteria of identification and examples from the Quaternary record of Northeastern Brasil
(Instituto de Geociências /Universidade Federal do Rio Grande do Sul, 2001)
Seismites and paleotsunamis deposits, assessing for paleoseismicity in Peru
(International Union For Quaternary ResearchMX, 2012)
[ENG] Human occupation records in Perú provide historical record of large earthquakes prior to the 20th century. In this study, we extend our knowledge of major events by evaluating the stratigraphy and chronology of ...
Seismites as a tool in the palaeoenvironmental reconstruction of fluvial deposits: The Cambrian Guarda Velha Formation, southern Brazil
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Soft-sediment deformation (SSD) is widely described in the literature, but there is no clear consensus regarding its origin and significance. Existing models for SSD in fluvial sediments do not clearly demonstrate a ...
Sediment deformation in Miocene and post-Miocene strata, Northeastern Brazil: Evidence for paleoseismicity in a passive margin
(ELSEVIER SCIENCE BV, 2011)
Stratigraphic intervals characterized by varied and complex styles of soft-sediment deformation structures are well preserved in Miocene and Late Pleistocene to Holocene deposits of a sedimentary basin located in Northeastern ...
Evidence of past seisms in Cusco (Peru) and Tzintzuntzan (Mexico): cultural relations
(International Union For Quaternary ResearchMX, 2012)
[ENG] (Evidence of ancient seisms in Cusco, Peru and Tzintzuntzan, Mexico and their cultural relations) At first sight the ancient pre-Columbian cultures seem to have had no awareness of seisms. Purhepecha and Andean ...
Earthquake-induced soft-sediment deformation structures in Upper Jurassic open-marine microbialites (Neuquén Basin, Argentina)
(Elsevier Science, 2011-04)
Penecontemporaneous decimetre-scale soft-sediment deformation structures are reported from the basal part of the Upper Jurassic-Lower Cretaceous Vaca Muerta Formation, in the Malargüe-Las Leñas area of the back-arc Neuquén ...
Soft-sediment deformation structures in gravelly fluvial deposits: A record of Cretaceous seismic activity in Patagonia?
(Pergamon-Elsevier Science Ltd, 2019-03)
Cretaceous sedimentary rocks corresponding to the Las Plumas Member of the Cerro Barcino Formation were deposited in the eastern margin of the Somuncurá - Cañadón Asfalto Basin. The analyzed succession records alluvial ...
Saline lake development in the Aptian post-rift phase of the Tucano Basin: Tectonic and paleogeographic implications
(2019-06-01)
The Aptian is the age of the evaporitic transitional megasequence in the Brazilian marginal basins as well as in the interior rift basins of the northeast region. The Marizal Formation is interpreted as a fluvial system ...
Paleoseismicity evidence in the region of lima (peru central coast)Evidencias de paleosismicidad en la Región de Lima (Costa del Perú Central)
(Universidad Nacional Mayor de San Marcos, Facultad de Ingeniería Geológica, Minera, Metalúrgica y Geográfica, 2013)
Structural evolution of The Collón Cura basin: Tectonic implications for the north Patagonian Broken Foreland
(Pergamon-Elsevier Science Ltd, 2019-08)
The distribution and timing of the deformation for the North Patagonian broken foreland is nowadays suggested by expansion and retraction of the orogenic activity during the middle to late Miocene Andean contractional ...
