Four samples of sandstone from deformed Aptian–Albian sediments and their less deformed Turonian cover at Sites 959 and 960 on the Côte d’Ivoire-Ghana Marginal Ridge yielded sufficient apatite for fission track analysis. Reduced mean track length values of 12.42 ± 0.16 μm to 13.67 ± 0.11 μm indicate that measured central ages, which range from 88 ± 4 Ma to 113 ± 4 Ma, have undergone partial resetting and are therefore apparent ages. Stochastic modeling of the fission track age and length parameters indicate that the samples have a strong predepositional signal, slightly modified by minor levels of prolonged postdepositional annealing (maximum temperatures <80°C). The preserved provenance-related signal records cooling through the apatite partial... |
