... but this structure attenuates eastwards and is replaced by the Glastonbury syncline which contains nearly 800 m of Mesozoic strata under Bridgwater Bay. The Central Bristol Channel fault zone has been traced eastwards towards Bridgwater Bay, and has a southerly downthrow of several hundred metres in mid-Channel...

...D. D. Hogarth; J. C. Roddick Abstract Five cobbles of metamorphosed ultramafic rock from the shores of southern Ireland are believed to have been derived from the ship Emanuel of Bridgwater in 1578. The Emanuel , one of Martin Frobisher's fleet, had loaded what was thought to be gold ore from three...

... Somerset and north Devon; (2) a broad flanking area of weak positive anomaly in the northern part of the Channel which may extend southeastwards across the Cothelstone fault into Bridgwater Bay; and (3) a local positive anomaly of over +20 mgal around Lundy Island. These anomalies are all superimposed...

...Jessica Don; John H. Shaw; Andreas Plesch; Daniel D. Bridgwater; Gbenga Lufadeju ABSTRACT Channel and fan systems in deep-water continental slopes respond to active deformation creating patterns within growth strata that record the history of deformation. These patterns provide important...

...B. J. A. Willigers; F. C. Mengel; D. Bridgwater; J. R. Wijbrans; J. A. M. van Gool Abstract The Paleoproterozoic Kangâmiut dikes are valuable time markers in the complex high-grade terranes of West Greenland. They are used to separate the Archean basement from areas affected by the Proterozoic...

...Minik T. Rosing; Nicholas M. Rose; David Bridgwater; Heidi S. Thomsen Abstract Investigations of the Isua supracrustal rocks in West Greenland allow us to identify the protoliths and alteration history for most Isua rocks. The protoliths consisted of alternating basalt and banded iron formation...

...L. Schiøtte; A. P. Nutman; D. Bridgwater Abstract Detrital zircons and their postdepositional overgrowths from three units of the "Upernavik" supracrustal association in the northern (Saglek) block of the Archaean Nain Province have been dated with the ion microprobe SHRIMP . In one unit, from...

...L. Schiøtte; W. Compston; D. Bridgwater Abstract Ion-probe U–Pb dating of igneous zircons from an acid metavolcanite belonging to the Nulliak supracrustal association of the Saglek area, northern Labrador, suggests an original age of 3776 ± 8 Ma (2σ), interpreted as the deposition age...

...A. P. Nutman; B. J. Fryer; D. Bridgwater Abstract The Nulliak (supracrustal) assemblage, the remains of ca. 3800 Ma succession of volcanic and sedimentary rocks, was broken up by intrusion of the protoliths of the early Archaean Uivak orthogneisses and then deformed, metamorphosed, and variably...

...L. Schiøtte; W. Compston; D. Bridgwater Abstract Rounded zircons included within igneous zircons from the Uivak I gneisses, northern Labrador, have ages of up to 3863 ± 12 Ma (2σ), showing the (former) existence of rocks that predate the Uivak gneisses by more than 100 Ma. The igneous zircons...
