Interplay of proximal and distal sources in Devonian–Carboniferous sandstones of the Clair Basin, west of Shetland, revealed by detrital zircon U–Pb ages
The Clair Basin is one of the Devonian sedimentary basins formed as a result of extensional tectonics in the aftermath of the Caledonian orogeny. The Devonian to Carboniferous Clair Group was deposited directly on Archaean basement, providing an opportunity to consider contrasting proximal and dista...

The Clair Basin is one of the Devonian sedimentary basins formed as a result of extensional tectonics in the aftermath of the Caledonian orogeny. The Devonian to Carboniferous Clair Group was deposited directly on Archaean basement, providing an opportunity to consider contrasting proximal and distal provenances. New secondary ion mass spectrometry detrital zircon U–Pb data and complementary heavy mineral data allow for a reinterpretation of potential source areas. Detrital zircons from the Clair Group yield ages ranging from c . 400 to 3700 Ma. All samples contain a group of Archaean ages ( c . 16–82%).
