In order to evaluate the petroleum potential of southern Switzerland (south-Alpine fold-and-thrust belt), gas geochemical investigations including free and adsorbed gases were combined with a basin modelling analysis. The palaeotectonic setting and Alpine orogenic movements were recognized as main controls in the evolution of the petroleum generation potential. Three main hydrocarbon provinces are distinguished: (1) The Arbostora anticline which developed from an Early Jurassic high has excellent but immature source rocks which probably at no time generated hydrocarbons because of their swallow level in the nappe edifice, (2) the Stabio anticline south of the Arbostora anticline in southernmost Switzerland where wet gases are observed at the surface that are likely to have been generated from Late Cretaceous to present day from Triassic source rocks occurring deeper in the nappe pile, and (3) the M. Generoso basin with prevailing petroleum generation in the Early Jurassic and possible minor generation in marginal areas during Cretaceous and Tertiary times. |
