Major and trace elements redistribution in weathered claystones from the Corumbatai Formation, Parana Sedimentary Basin, Sao Paulo, Brazil
(Soc Brasileira Geologia, 2017-10-01)
We studied 30 samples from 10 mining fronts of clayish rocks of the Corumbatai Formation, in the region of the Santa Gertrudes Ceramic Pole (Sao Paulo, Brazil), in order to evaluate the variation of rare earth elements ...
Evaluation of the potential for dissolved oxygen ingress into deep sedimentary basins during a glaciation event
(Wiley Blackwell Publishing, Inc, 2018-04)
Geochemical conditions in intracratonic sedimentary basins are currently reducing, even at relatively shallow depths. However, during glaciation-deglaciation events, glacial meltwater production may result in enhanced ...
Geoelectrical prospection of disseminated sulfide mineral occurrences in Camaquã Sedimentary Basin, Rio Grande do Sul State, Brazil
(2012-12-01)
The mineral exploration is a complex activity that should involve a combination of direct and indirect techniques of geological investigation. The growing demand for base metals in the national and international market ...

U-ages in soils and groundwater evidencing wet periods 400-600 kyr ago in southeast Brazil
(Elsevier B.V., 2007-07-01)
U-238 and its radiogenic daughter U-234 have been utilized for dating soil formation and groundwater residence time during the last 1.5 million years, in this case based on the U-clissolution/precipitation occurring during ...
