The simple and effective technique of fission track etch has been applied to determine trace concentration of uranium in human blood samples taken from two groups of male and female participants: leukemia patients and healthy subjects group. The blood samples of leukemia patients and healthy subjects were collected from three key southern governorates namely, Basrah, Muthanna and Dhi-Qar. These...
Abstract. To enable the separation of pre- and postdepositional components length distribution (partially annealed) horizontal confined fission tracks, is corrected by deconvolution. Probabilistic least-squares inversion corrects natural track histograms for observational biases, considering variance in data, modelization, prior information. The histogram validated its variance–covariance matri...
Ar–Ar and fission-track dating from four low-grade sections in the Alpujárride Complex sheds light on the timing of the early contractional history of these high-pressure metamorphic units, and their subsequent exhumation during the early Miocene extensional collapse of the Betic orogen. White mica grains from the lowest-grade rocks yield partly reset detrital Ar–Ar ages; where deformation and ...
The Isère River system drains parts of the Western Alps in south-eastern France. Zircon fission-track data of the Isère River and its tributaries show a range of apparent cooling ages from about 7 to 150 Ma. Zircons with Jurassic to early Tertiary cooling ages are derived from partially reset or non-reset sedimentary cover units of the internal and external Alps, while grains belonging to the m...
Abstract The early exhumation history of the Tauern Window in European Eastern Alps and its surface expression is poorly dated quantified, partly because thermochronological provenance information are sparse from Upper Austrian Northern Alpine Foreland Basin. For first time, we combine a single‐grain double‐dating approach (Apatite Fission Track U‐Pb dating) with trace‐element geochemistry anal...
