...GARRY ALLAN GAUSS; MICHAEL ROBERT HOUSE Abstract Two different successions of Middle and early Upper Devonian rocks are described from the north coast of Cornwall around Padstow. These have been named the Trevone and Pentire successions. The former is seen especially south and west of Camel Estuary...

... the background se imentation to much of the basinal sedimentation from middle Devonian to early Carboniferous times. Some 2000 m of rapidly-sedimented argillites have been reported in the middle Devonian of the Trevone Basin (Beese 1982), but in the early Carboniferous the successions are much thinner...

...), and south, by Middle Devonian successions. We suggest that the upright folds in the Polzeath Slates about the Camel estuary are unrotated D1 structures produced during the inversion of the Trevone Basin. The relationships which we describe on the coast appear to parallel some of those in the newly...

.... Drag in the overlying grey slates clearly demonstrates the sense of movement. The stratigraphy southwards to Boobys Bay comprises the well-established Pentire and Trevone successions (Gauss & House 1972) of contrasting Middle to Upper Devonian facies. South-west of Tresungers Point the coast turns more...

... from Tor Bay to Bodmin, and separates a redefined Trevone (north Cornwall) Basin from the south Cornish Basin. A moderate to steeply dipping slaty cleavage (Dl) dips southward throughout the area and is associated with early E–W major folds, inferred to be north- or upward-facing, which plunge gently...

... was indeed significant and of considerable importance. We agree with Selwood & Thomas that major thrusts exert considerable control over the stratigraphic successions but deduce that there are also major recumbent folds present. Selwood and Thomas's arguments for an essential continuum of northwards...

... of the Middle to Late Devonian Trevone Slate Formation and has a stratigraphic age of ~388–375 Ma (Givetian–Frasnian). The slates were deposited as outer-shelf to deep-water basinal mudrocks in the Trevone Basin and subsequently metamorphosed during the Variscan Orogeny. They contain illite-muscovite, chlorite...

... Borderland and the Midland Valley of Scotland. The Middle ORS, of Middle Devonian age, is essentially present only in the Orcadian Basin, where it accounts for most of the succession. Elsewhere, all of Middle Devonian and much of Upper Devonian time, some 20 Ma, is represented by an unconformity between...

It was not until the Silesian that Variscan deformation affected basin development and caused its deformation (see this chapter). The upper Palaeozoic Orogenic Province...

Sandstone successions were recognized and separated from others because they were clastic, of non-marine character, generally younger than marine Lower Palaeozoic successions and generally older than marine Carboniferous sediments. Outcrop areas were divided between those that contained marine and non...
