Exploration in the Faroe–Shetland Basin on the Faroese Continental Shelf has revealed thick and complex volcanic successions and discovery of inter-volcanic oil-bearing siliciclastic sandstone fan deposits in the central parts of the basin. The possibility for such play types at the fringe of the North Atlantic Igneous Province requires a better understanding of the interaction between competing sedimentary and volcanic depositional transport systems. We have re-examined volcanic units in cuttings from exploration wells in the greater Judd Sub-basin area for evaluation of facies and geochemical affinity. This allows for chemostratigraphical correlation of wells to the absolute radiometrically age-constrained Faroe Islands Basalt Group. The collective well data were subsequently tied to a regional interpretation of 2D seismic data which facilitated a detailed interpretation of temporal development of the volcanic successions in the Judd Sub-basin area in terms of geometry, volcanic facies, depositional environment, and interdigitation with non-volcanic sedimentary units.

The Judd Sub-basin was influenced by major volcanic phases during pre-breakup and syn-breakup. The influence was both direct, in the form of volcanic deposits, and indirect, in the form of obstructing established sedimentary transport systems and creating new provenance areas. The volcanic transport systems reached different areas of the Judd Sub-basin at different times during pre-breakup volcanism. The earliest incursion in the west was during late Mid Paleocene (T-sequence T31/T32). With at least three stratigraphically discrete incursions of volcanic material into the Judd Sub-basin, possibilities arise for sub- and inter-volcanic stratigraphic and structural traps for each incursion.

法罗-设得兰盆地法罗大陆架勘探揭示了厚而复杂的火山层序，并在盆地中部发现了火山间含油硅质碎屑砂岩扇沉积物。在北大西洋火成岩省边缘出现这种类型的可能性需要更好地了解相互竞争的沉积和火山沉积传输系统之间的相互作用。我们重新检查了大贾德次盆地地区勘探井岩屑中的火山单元，以评估相和地球化学亲和力。这允许井与绝对辐射年龄限制的法罗群岛玄武岩组的化学地层相关性。

贾德次盆地在分裂前和同期分裂期间受到主要火山阶段的影响。这种影响既有直接的，以火山沉积物的形式，也有间接的，以阻碍已建立的沉积运输系统和创造新的物源区的形式。在破裂前的火山活动期间，火山输送系统在不同时间到达贾德次盆地的不同区域。西部最早的入侵是在中古新世晚期（T-序列T31/T32）。至少有 3 次地层离散的火山物质侵入 Judd 次盆地，每次侵入都可能出现火山下和火山间地层圈闭和构造圈闭。
