Mesozoic break-up of SW Gondwana: implications for regional hydrocarbon potential of the southern South Atlantic
- D. Macdonald, D. Macdonald, +9 authors D. Paton
- Geology
- 1 March 2003
Abstract This work provides new palinspastic palaeofacies reconstructions of SW Gondwana incorporating rotation of a Falkland/Malvinas microplate. We discuss the implications of this for the tectonic… Expand
40Ar/39Ar dating of hydrothermal activity, biota and gold mineralization in the Rhynie hot-spring system, Aberdeenshire, Scotland
- D. Mark, C. M. Rice, +4 authors J.K.W. Lee
- Geology
- 15 January 2011
This study presents a new high-precision 40Ar/39Ar age for the Devonian hot-spring system at Rhynie. Hydrothermal K-feldspar sampled from two veins that represent feeder conduits and a hydrothermally… Expand
Arthropods invade the land: trace fossils and palaeoenvironments of the Tumblagooda Sandstone (?late Silurian) of Kalbarri, Western Australia
- N. Trewin, K. J. Mcnamara
- Geology
- 1994
The trace fossils of the Tumblagooda Sandstone (?late Silurian) of Kalbarri, Western Australia are spectacular in their variety and preservation. They provide a unique insight into the activities of… Expand
A Devonian auriferous hot spring system, Rhynie, Scotland
- C. M. Rice, W. Ashcroft, +11 authors G. Turner
- Geology
- Journal of the Geological Society
- 1 March 1995
The Early Devonian Rhynie hot spring system is the oldest known and is of the low sulphidation type. It extends for at least 1.5 km along a major fault zone defining the western margin of an outlier… Expand
Geological setting of the Early Devonian Rhynie cherts, Aberdeenshire, Scotland: an early terrestrial hot spring system
- C. M. Rice, N. Trewin, L. I. Anderson
- Geology
- Journal of the Geological Society
- 1 March 2002
Abstract: The drilling of nine cored boreholes, including a deep hole (233 m) to a gabbroic basement, in the vicinity of the Rhynie chert locality has resulted in a major revision of the structure… Expand
An Early Devonian arthropod fauna from the Windyfield cherts, Aberdeenshire, Scotland
- L. I. Anderson, N. Trewin
- Biology
- 1 May 2003
New terrestrial and freshwater arthropods are described from the Windyfield cherts, a suite of silicified sinters deposited 700m north-east of the Rhynie cherts and part of the same Early Devonian… Expand
Palaeoecology and sedimentology of the Achanarras fish bed of the Middle Old Red Sandstone, Scotland
- N. Trewin
- Geology
- 1986
The Achanarras fish bed of Middle Devonian age in the Orcadian Basin was deposited in a large freshwater lake of variable productivity in which thermal stratification was normally developed. The fish… Expand
Subaqueous silicification of the contents of small ponds in an Early Devonian hot-spring complex, Rhynie, Scotland
The Early Devonian Rhynie and Windyfield cherts of northeast Scotland originated as siliceous sinters deposited by hot springs. Silicification affected both subaerial and subaqueous environments,… Expand
Depositional environment and preservation of biota in the Lower Devonian hot-springs of Rhynie, Aberdeenshire, Scotland
- N. Trewin
- Geology
- 1993
The Lower Devonian plant- and arthropod-bearing cherts of the Rhynie area of Aberdeenshire, NE Scotland, were deposited from silica-rich waters emanating from the hot-springs of a precious-metal (Au)… Expand
Stratigraphy and sedimentology of the Permian of the Falkland Islands: lithostratigraphic and palaeoenvironmental links with South Africa
- N. Trewin, D. Macdonald, C. Thomas
- Geology
- Journal of the Geological Society
- 1 January 2002
Comparison of the facies, ichnology and palaeocurrent patterns of the Permian of the Falkland Islands and the Dwyka, Ecca and Beaufort (part) groups in South Africa supports the hypothesis that the… Expand
