Corso Sedimentary Organic Matter: characterization and applications
Docente Prof. M. Stephenson, BGS, UK
CFU e ore
Finalità The course will examine the character of sedimentary organic matter (SOM) and palynology and its various uses in palaeoenvironment, palaeoclimatology and fossil fuel research (including source rock, coal bed methane and shale gas evolution). Several case studies will show how sedimentary organic matter can be used to understand key Phanerozoic events, such as the Hirnantian glaciation, the Carboniferous-Permian glaciation, the end-Permian extinction, the K-T extinction and the Palaeocene-Eocene Thermal Maximum (PETM). Case studies will also show how the analysis of palynology and sedimentary organic allow understanding of source rock generation for conventional hydrocarbons as well as aspects of the primary controls on unconventional shale gas and coal bed methane prospectivity.
