Permian palynostratigraphy of the Claromecó Basin, Argentina
(Taylor & Francis Ltd, 2014-03-07)
The first palynozonation for Permian strata of the Claromecó Basin (Argentina) is formally proposed, based on palynological assemblages recovered from the UTAL.CMM1 La Estrella.x-1 and UTAL.CMM1 Cruz de Sur.x-1 boreholes, ...
Palynostratigraphy of the late palaeozoic of Uruguay, paraná basin
(Elsevier Science, 2011-09)
A biozonation for the Permian strata of Uruguay is proposed based on published data from boreholes 201, 221, CLSC 3, 4, 11, 13 and 24 drilled by Dirección Nacional de Minería y Geología of Uruguay (DINAMIGE), as well as ...
Geochronological data from the Faxinal coal succession, southern Parana Basin, Brazil: A preliminary approach combining radiometric U-Pb dating and palynostratigraphy
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
A radiometric zircon age of 285.4 +/- 8.6 Ma (IDTIMS U-Pb) is reported from a tonstein layer interbedded with coal seams in the Faxinal coalfield, Rio Grande do Sul, Brazil. Calibration of palynostratigraphic data with the ...
Chronostratigraphic constraints and paleoenvironmental interpretation of the Romualdo Formation (Santana Group, Araripe Basin, Northeastern Brazil) based on palynology
(2020-12-01)
The Santana Group of the Araripe Basin is a major paleontological unit in Brazil, incorporating two important Cretaceous Konservat-Lagerstätten. The lower formations are Aptian, but the age of the uppermost Romualdo Formation ...
Mid-latitude Paleogene dinoflagellate cysts from offshore Santa Catarina (Pelotas Basin, Southern Brazil): Taxonomy and biochronostratigraphy
(2021-10-01)
Palynological assemblages have been reported in pre-Quaternary deposits of the Pelotas Basin, except in the Santa Catarina Platform, where micropaleontological information is still restricted to calcareous microfossils. ...
Global biostratigraphic comparison and correlation of an early Cisuralian palynoflora from Bolivia
(Taylor and Francis Ltd., 2015-10)
This paper presents new data about Early Permian (Cisuralian) strata, palynostratigraphy and absolute dating from the Copacabana Formation in central Bolivia. Recent stratigraphic and palynologic data from marine and ...
Pennsylvanian and Cisuralian palynofloras from the Los Sauces area, La Rioja Province, Argentina: Chronological and paleoecological significance
(Elsevier Science, 2010-08)
Three outcrops of the Libertad and Sauces Formations from the Los Sauces area La Rioja Province, western Argentina, yielded the nine palynoassemblages studied here. Two assemblage zones are defined on the basis of the ...
Upper Silurian miospores from the Precordillera Basin, Argentina: biostratigraphic, palaeonvironmental and palaeogeographic implications
(Cambridge University Press, 2013-08)
This study is concentrated on Ludlow (to Pridoli?) miospores from the Los Espejos Formation at the Quebrada Ancha locality, Central Precordillera, San Juan Province, Argentina. The Ludlow age is in agreement with the age ...
