摘要：

Oil-bearing fluid inclusions trapped within authigenic K-feldspar in Late Jurassic reservoirs throughout the UK Atlantic margin are evidence for an early oil migration event from Late Jurassic source rocks in the Faeroe-Shetland Basin. Previous compound-specific isotope studies confirm the hydrocarbon provenance. Temperature-composition-time data show that the Late Jurassic source rocks were oil mature 113 +/- 3.5 Ma (2 sigma). This new (40)/Ar/39Ar atithigenic K-feldspar age shows that the Late Jurassic source rocks were oil mature 30-40 m.y. prior to current estimates.
