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 ...
Taming the control of chronology in ancient agricultural structures in the Calchaqui Valley, Argentina: Non-traditional data sets
(Academic Press Ltd - Elsevier Science Ltd, 2010-12)
The absolute chronology of the agricultural soil from organic matter has always been difficult to measure due to several reasons. In our work on the Prehispanic agriculture in the Calchaqui Valley - Argentina, however, an ...
OSL age determinations of Pleistocene fluvial deposits in Central Amazonia
(Academia Brasileira de Ciências, 2010)
Absolute dating methods have been used in chronological studies of geological processes and sedimentary units of Quaternary age in Central Amazonia, Brazil. Although radiocarbon dating has been very useful in archaeological ...
