We examine in detail the organic material of the Yacoraite Formation (Maastrichtian-Danian), the most important host rock in the Salta Rift Basin. We also study the geological evolution of the Salta Basin to understand the burial and temperature history with respect to organic matter maturation and hydrocarbon generation.
With the discovery of an ubiquitous deep biosphere on Earth inevitably the question on its potential carbon and energy sources arises, therefore, several studies have been carried out to prove that organic carbon rich lithologies like lignites, coals and kerogen could act as potential “feeder” lithologies for the deep biosphere, leading to the deduction that abiotically driven degradation reactions of the buried organic matter will provide substrates, such as water – soluble low molecular weight organic acids (LMWOA), for microbial activity in deep sediments.
Aim of the CEL paleofire project is to better understand the role of fire on past landscape evolution of the central European lowlands (CEL) on different spatio-temporal scales using a multiple fire proxy approach. Paleofire regimes will be linked with interacting driving mechanisms, climate, vegetation and human activity.
In this study solid bitumens from SE Turkey and W Iran are being comprehensively characterized using a combination of different established and advanced geochemical analyses. Furthermore, some solid reservoir bitumens and related oils and source rocks from Austria have been included as a separate sub-project.
This project addresses the enhancement of understanding physicochemical processes as well as their controls and mechanisms involved in generation of oil and gas, its primary migration in and expulsion from organic-rich, fine-grained siliciclastic source rock in petroleum systems located on the Norwegian continental shelf, central North Sea.
The aim for this study is to reconstruct the timing of petroleum generation, the changing gas/oil ratio (GOR) of the petroleum and its physical properties during maturation. The timing and extent of petroleum generation depends on both the thermal history of the source rock and the reaction kinetics of hydrocarbon generation from kerogen.
Natural gas mixtures trapped in mineral-hosted fluid inclusions provide valuable information about the origin, generation and migration of gases in the geological record. A new on-line method for simultaneous measurements of stable carbon and nitrogen isotope ratios of fluid inclusion gases was developed at the GFZ.
