Chronostratigraphy and radiocarbon age inversion in the Holocene regressive barrier of Paraná, southern Brazil
(2008-07-07)
Twenty-two 14C datings were performed at the central sector of the Paraná coast to define Holocene regressive barrier evolution. The barrier Pleistocene substratum was ascribed an age between 40 400 and 30 000 yr BP, but ...

Marcos estratigraficos regionais na Formacao Palermo: caracterizacao dos picos radioativos
(1994-12-01)
During a basinal scale study on Palermo Formation (Upper Permian, Parana Basin) high elevated Gamma Ray picks were identified mainly in the lower third of that stratigraphic unit. Those Gamma Ray signatures have been used ...

Chronostratigraphy and significance of the Rugosa group (Cruziana, trace fossil) in the Ordovician strata of the South American Central Andean BasinLa chronostratigraphie et l’importance du groupe Rugosa (ichnofossiles) dans l’Ordovicien du bassin des Andes centrales d’Amérique du Sud
(Elsevier France-editions Scientifiques Medicales Elsevier, 2015-02)
Although most trace fossils display long temporal ranges, certain forms as the Paleozoic mostly trilobite trace Cruziana have particular biostratigraphic significance. The evolution and replacement of trilobite families ...
