Apatite fission-track analysis was applied to Triassic and Cretaceous sediments from the South-Iberian Continental Margin to unravel its thermal history. Apatite fission-track age populations from Triassic samples indicate partial annealing and point to a maximum temperature of around 100–110 °C during their post-depositional evolution. In certain apatites from Cretaceous samples, two different...

Manual identification of fission tracks has practical problems, such as variation due to observer-observation efficiency. An automatic processing method that could identify fission tracks in a photomicrograph could solve this problem and improve the speed of track counting. However, separation of nontrivial images is one of the most difficult tasks in image processing. Several commercial and fr...

in the present research, we want to simulate the fission process of the excited nucleus 207at produced in fusion reaction 19f+188os in the framework of the modified statistical model with considering the effects of projection of spin about the symmetry axis, k, and temperature. in our simulation, we calculate the fission cross section and anisotropy of the fission fragment angular distribution ...

The provenance of Early Cretaceous sandstones dredged on the northern margin Demerara Plateau, offshore French Guiana and Suriname, reveals sediment routing system that prevailed through Equatorial Atlantic rifting. Fission-track analysis U–Pb dating 310 111 detrital zircons, respectively, have been performed. Microfacies inherited cooling ages suggest were deposited in shallow marine environme...

In this work, we describe a new method for parallelizing the source iterations in a Monte Carlo criticality calculation. Instead of having one global fission bank that needs to be synchronized as is traditionally done, our method has each processor keep track of a local fission bank while still preserving reproducibility. In doing so, it is required to send only a limited set of fission bank si...

In geological minerals, tracks of fragments from spontaneous fission of U nuclei accumulate over geological time scales and are widely used for fission-track dating and thermochronology [1, 2]. In our recent studies, we tackled the problem how solids exposed to energetic heavy ions cope with the simultaneous exposure of external pressure. This combination of ion irradiation and pressure is suit...
