The Th/U ratio in minerals by a fission-track technique: application to some reference samples in order to estimate the influence of Th in fission-track dating
(Pergamon-elsevier Science LtdOxfordInglaterra, 2002)
Novel calibration for LA-ICP-MS-based fission-track thermochronology

Zircon fission track and U-Th-Pb in situ dating of Rio Parana Formation, Parana Basin, Brazil
(Soc Mexicana Fisica, 2010-02-01)
Ages of zircon from sedimentary samples of Rio Parana Formation, belonging of Bauru Group, north of Parana Basin, Brazil, has been determined by zircon Fission Track and U-Th-Pb in situ dating methods. The obtained ages ...
New constraints on ages of glasses proposed as reference materials for fission-track dating
(Wiley-Blackwell, 2007-06-01)
New analyses have been performed in order to enhance the data-set on the independent ages of four glasses that have been proposed as reference materials for fission-track dating. The results are as follows. Moldavite - ...

Annealing experiments on induced fission tracks in apatite: Measurements of horizontal-confined track lengths and track densities in basal sections and randomly oriented grains
(2006-01-01)
To improve kinetic models for apatite fission-track annealing, we present new experimental annealing data that complement previously published data. To determine the degree of annealing of induced tracks, surface density ...
Recognition of Cretaceous, Paleocene, and Neogene tectonic reactivation through apatite fission-track analysis in Precambrian areas of southeast Brazil: Association with the opening of the south Atlantic Ocean
(2003-01-01)
Apatite fission-track analysis was used for the determination of thermal histories and ages in Precambrian areas of southeast Brazil. Together with geological and geomorphologic information, these ages enable us to quantify ...
