Étude d'une fosse du 13ème siècle par les marqueurs biogéochimiques : chantier archéologique du Louvre (Paris)

Abstract

In order to study a pit from the thirteenth century in the archeological site of Louvre (Paris) some biogeochemical markers such as n-alkanes, fatty acids and sterols have been used. A number of criteria allows us to estimate the impact of bacterial biodégradation of the ofganic matter (Carbon Preference Index). Informations about utilization, functioning and evolution of this pit have been obtainde by organic markers studies.
