This study comprises newly collected organic geochemical and petrological data on quality, quantity, maturity as well as the depositional environment of various organic matter-rich stratigraphic units in Morocco and the Central Congo Basin, DRC. In order to gain information about type, and maturity of the organic matter (OM) geochemical techniques were carried out on a total of 518 samples. Corg measurements, elemental analysis (carbon, sulphur, Fe, V, and Ni), vitrinite reflectance measurements, Rock-Eval pyrolysis, bulk kinetic measurements, and GC/GC-MS were used to determine the maturity, quality and quantity of the organic matter as well as to define the environment of source rock deposition. In addition, 1D modeling was carried out for one locality in northern Morocco (Aït Moussa) and for two wells from the Central Congo Basin to obtain information on burial thermal and maturation history. For the Aït Moussa model, specific bulk kinetic parameters were used to evaluate the petroleum generation and timing. weiterlesen
