Silurian Source Rock System in Time and Space

mulated in relatively confined foreland basin settings whereas others were formed on a broad but tectonically and glacially modified Gondwana shelf. This contribution illustrates that the depositional, temporal and ‘tectonic’ variations for one of the ‘so-called’ global source rocks events can be considerable. Generalizations and un-calibrated use of models, analogues and properties should not be made.
