The stratigraphy and structure of the Devonian Rocks in the Quantock Hills, West Somerset

Spatial variation in solutional denudation and soil moisture over a hillslope hollow

“…No bedrock is exposed at the study site but a quarry at the mouth of the Combe (Figure 1) shows the bedrock to be massively bedded reddish purple metamorphosed quartzites dipping at 30" to the northwest. Webby (1965) places these rocks in the Hangman Grits Group of the Old Red Sandstone succession of the Middle Devonian. The succession visible in the quarry is assumed to be lithologically similar to the rock underlying the study site.…”

“…The hydrological processes operating on a hillslope have been investigated and described in detail (Weyman, 1973;Kirkby, 1978; Anderson and Burt, 1978). However, the study of hillslope solutional denudation has received less attention.…”

The geochemistry of oil in Cornish granites

“…Data from the Cornish samples were compared with new analysis of a previously studied Jurassicsourced oil seep at Mupe Bay, Dorset, 200 km to the east in the Wessex Basin (Parfitt & Farrimond 1998), and from organic-rich samples at several other stratigraphic levels. The samples were from black Devonian limestone in the Quantock Hills near Bridgwater, Triassic black shale from Blue Anchor and Oligocene lignite at Bovey Tracey (Webby 1965;Edwards 1976;Warrington & Whittaker 1984) (Fig. 1).…”

The Isle of Wedmore relay ramp: how fault evolution created King Alfred's historic landmark

“…Proceedings of the Geologists' Association Somerset (e.g., the Mendip Hills) was deposited in a fluvial environment (e.g., Barclay et al, 2015), whilst the Devonian rocks in the south-west of the county (Exmoor and Quantock hills) are dominated by sandstones and mudrocks that were deposited in both marine and non-marine environments (e.g., Webby, 1965). The Lower Carboniferous sequence (Carboniferous Limestone) represents a change to marine conditions, with deltaic siliciclastic rocks and coal dominating the Upper Carboniferous (e.g., Green, 1992).…”
