... Fault Zone (OHFZ) in NW Scotland ( Figs 1 , 2 ) is a reactivated, crustal-scale fault developed within Archean–Paleoproterozoic basement gneisses of the Laurentian craton (e.g. Sibson 1977 ; Walker 1990 ; Fettes et al. 1992 ; Butler et al. 1995 ; Imber 1998 ; MacInnes et al. 2000 ; Imber...

... conglomerates. The aim of this contribution is to focus on one important question: is their controversial model for the Donegal Dalradian supported by studies of the stratigraphically equivalent Dalradian rocks of the SW Highlands of Scotland? If an orogenic unconformity is present in the Dalradian Supergroup...

The significance of this area is its close proximity to what are two of the largest structures in Scotland: the Great Glen Fault which...

The Leven Schists sensu stricto , i.e. that formation which stratigraphically underlies the Ballachulish Limestone,are confined to the floor of Glen Creran and the NE-trending Airds Hill belt, where the unit exhibits facies changes. Clearly, Lambert et al . sampled rocks other than...

...John A. Howe; Julian Overnell; Mark E. Inall; Andrew D. Wilby Synopsis Loch Etive in Argyll on the west coast of Scotland, is a 30 km long, up to 145 m deep sea loch of glacial origin. A unique side-scan sonar image with new accompanying bathymetric data of the upper basin of the loch has been...

... ( Charlesworth 1926 ; Kerr 1982 ; McCabe et al . 1998 ; Salt & Evans 2004 ; Bradwell et al . 2008 and others). Three decades ago, it was suggested that high-arctic marine deposits formerly seen in two claypits in SW Scotland were possible representatives of the high-arctic Errol Clay Formation...

... Abstract M r A. W. B aird writes: Roberts, Smith & Harris (1984) have produced a significant piece of structural mapping in Glen Dessary but I cannot agree with their interpretation of its regional significance. I propose an alternative which does not involve the unlikely situation of regional...

...Aaron W. Hunter; Neil D. L. Clark Synopsis Despite a long history of investigation, articulate crinoids from the Jurassic of Scotland have not received great attention compared to their counterparts in Southern England or continental Europe; this is thought to be largely due to poor preservation...

... across the Moine Nappe, northern Scotland. U–Pb zircon and Re–Os molybdenite dating of the Loch Shin and Grudie plutons, which lie immediately SW of the NW–SE Loch Shin–Strath Fleet fault system, yield c . 427–430 Ma ages that overlap within error. They also coincide with previously obtained U–Pb zircon...

...D. Powell; M. Brook; A. W. Baird Abstract A cross-cutting pegmatite emplaced into low grade, non-migmatitic, Proterozoic, Moine metasediments on the western sea-board of Inverness-shire, Scotland, gives Rb-Sr muscovite ages of 746–776 Ma which are interpreted as minimum estimates for the age...

Although the upper (roof) thrust of some duplexes may be folded and bulged by underlying imbricate slices (in accordance with simple duplex models), the footwall to these roof...
