Paiva Kenitiro Suguio Multidisciplinaria (Ciencias Naturales y Exactas) sea level Pleistocene São Paulo State thermoluminescence ages The Cananéia (Upper Pleistocene) and the Comprida Island (Holocene) formations, outcropping in the Compridaisland (SP) have been mapped using geomorphological and lithological criteria. Only one sample ofthe Cananéia Formation, collected in the homonymous island in front of the Comprida Island, was beyondthe limit of the standard radiocarbon method.But since the publication of the geological map of the area in 1978, there has been some doubt on the realoccurrence of Pleistocene deposits in southern extremity of Comprida Island.This paper deals with the results of thermoluminescence (TL) ages of eight samples from Comprida Island,which corroborate the Pleistocene age assumed during mapping surveys of these deposits. On the otherhand, possible interpretations of the obtained ages, in relation to their depositional environments and relatednorthern hemisphere Quaternary glaciations, are presented. 2003 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32775110 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.1 Vol.75 |
