(Pergamon-Elsevier Science Ltd, 2017-11)
At the northwestern portion of the Tandilia System, a detailed structural analysis on the Precambrian sedimentary units exposed in the quarries of the Olavarría-Sierras Bayas area was carried out. These units exhibit ...
Reconstructing paleoenvironmental conditions through integration of paleogeography, stratigraphy, sedimentology, mineralogy, and stable isotope data of lacustrine carbonates: an example from early Middle Triassic strata of southwest Gondwana, Cuyana Rift, Argentina
(Springer Nature Switzerland AG, 2021)
Reconstructing continental paleoenvironmental conditions (temperature, precipitation, hydrology, and hydrography) is essential for constraining the infuences on terrestrial ecosystems, sediment and solute yields to the ...
