英国大西洋边缘晚侏罗世储层中自生钾长石中捕获的含油流体包裹体是法罗-设得兰盆地晚侏罗世烃源岩早期石油运移事件的证据。先前的化合物特定同位素研究证实了烃的来源。温度-成分-时间资料表明，晚侏罗世烃源岩为113 ± 3.5Ma（2σ）的油成熟期。这一新的自生钾长石40 Ar/39 Ar年龄表明，晚侏罗世烃源岩的油成熟期为3000 ~ 4000万年。在目前的估计之前。
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 (2σ). This new 40Ar/39Ar authigenic K-feldspar age shows that the Late Jurassic source rocks were oil mature 30–40 m.y. prior to current estimates.
