This seems to be a basis for an alternative to other statistical ones [Monte Carlo (Lutz

We fit fanning and parallel Arrhenius models to the 31 experiments using a recently developed modelling procedure, which provides efficient estimates of the kinetic parameters and their precisions. For both fanning and parallel models the

Anfertigung mikroskopischer Präparaterheinisches Schiefergebirge. The study included age determinations, confined track length and chemical analysis as well as computer modeling of the thermal history. Apatite fission track ages vary between 130±11 Ma and 239±13 Ma. Mean confined track lengths range from 12.35±0.36 tm to 13.20±0.73 µm.

Allgemeines über die Anatomie der Pflanzenoic and Hercynian basement. Apatite fission-track data from Hercynian granitoids to the east of the basin show that the intrusives were being actively eroded throughout the Jurassic and Cretaceous; however, exactly when these rocks first became exposed and eroded is not clear. In this study we have

There are three possible explanations for the recorded cooling: 1) a decrease in the geothermal gradient, 2) erosion, or 3) sub-surface cooling in response to a long-term decrease in the paleo-mean annual
