...-directed subduction beneath Laurentia. The almost complete absence of plutons of this age along-strike in mainland Scotland suggests a change in subduction angle and/or the distance between the subduction zone and the Laurentian margin. Intrusion of the Ronas Hill Granite ( c. 427 Ma) was approximately...

Both the cover and basement are fractured and well tests suggest that there are fluid pathways through the basement connecting sedimentary...

... are presently being mined on land. With large high-grade and easily accessible deposits becoming more and more difficult to find, marine mineral resources have attracted much attention from the industry ( Rona 1981 ; Petersen 2015 ). This is especially true when a semi-infinite deposit of rare earth elements...

... at 989 ± 12 Ma, based on U–Pb zircon age data ( Connelly & Heaman 1993 ). The zircons are from a mylonitized granite, deformed during the juxtaposition of two terranes (Lac Joseph and Molson Lake terranes), and the 989 ± 12 Ma is defined by the lower intercept, interpreted as recording the timing...

These, presumably extensional, tectonics were probably the driving force behind the formation of the whole north European epeiric sea and must be related, in turn, to the opening of the oceanic central Atlantic and Alpine...

The early Geological Survey workers debated whether the acid gneisses represented deformed granites which intruded the metase-diments or whether they represented an older basement on which the sediments had been laid down. During the discussion that followed the reading of the classic paper...

... of the writer’s tests seem to confirm this conclusion if the igneous source of the sediments resembles a granite. An analysis of the data bearing on the radioactivity of deep-sea deposits and oil shales indicates no evidence of a general increase in radioactivity with slowness of deposition. The bearing...

... a faulted contact against the Ronas Hill Granite (RHG, Fig. 1 ). This granite, like the Sandsting Complex, is an intrusion of approximately Late Devonian age (Rb/Sr 358 × 8 Ma, Miller & Flinn 1966 ) and is therefore younger than the Eshaness succession. However, its lack of any discernible contact...

The dolerite is distributed with a well...

The presence of off-shore Caledonian granites west of the front is compatible with the position of the Ronas Hill granite, much of which is west of the front in Shetland. Underhill, like others before him, finds no room in the Moray Firth area for the 65 km post-Devonian...

.... Most fractured basement plays are associated with the development of up-faulted buried hill traps ( Biddle and Wielchowsky 1994 ), usually in extensional tectonic settings: the reservoirs occur in the footwalls of major normal faults. Fractured granitic basement has proved to be highly productive...
