Résumé

Une étude systématique des contenus organiques de faciès riches en matière organique, provenant du bassin yprésien de Tunisie centro-septentrionale, a permis de montrer que la matière organique était exclusivement dʼorigine marine (lignée II), et nʼavait pas atteint, à lʼaffleurement, la fenêtre à huile. Cette étude suggère que la dynamique du bassin yprésien a joué un rôle dans la distribution, la préservation et la composition de la matière organique. LʼYprésien a connu un événement anoxique favorable à lʼaccumulation et à la préservation de bonnes quantités de matière organique, résultant dʼune intense productivité primaire.

Abstract

The geochemical analysis of the organic-rich facies from the Ypresian basin in central-northern Tunisia shows that the organic matter is marine originated (type II) and displays a low thermal maturity level in outcropping samples. This study proves that the distribution, conservation and, therefore, the composition of the organic matter have been controlled by the dynamic of the Ypresian basin. The Ypresian period corresponds to an anoxic event, which led to the accumulation and preservation of good quantities of organic matter derived from a high primary production. To cite this article: A. Arfaoui, M. Montacer, C. R. Geoscience 338 (2006).
