Microfluorimetry applied to organic diagenesis study.


Microfluorimetric analyses, using new procedures have been applied on three sedimentary basins, each of them exhibiting a specific thermal history. The results have been compared to other optical and geochemical maturity parameters. It appears that the spectral fluorescence parameters cannot be used as rank parameters, because of their complex evolution with increasing diagenesis. However, they are better parameters than vitrinite reflectance for thermal maturity assessment as far as hydrocarbon generation is concerned. For instance, it is shown that different types of fluorescent materials release hydrocarbons at different levels of thermal evolution in a given series. On the other hand, alteration analyses appear to be efficient and objective tools for the punctual detection of hydrocarbons in a sample.
