Journal Article
Published: 27 May 2009
Geological Magazine (2009) 146 (6): 851-875.
.... As a case study we used the Shiant Isles Main Sill that is widely regarded as a classical example of a multiple, picrite–picrodolerite–crinanite alkaline sill. This sill is currently interpreted as having been formed by several olivine phenocryst-rich pulses of magma, which were successively emplaced...

...C. M. B. Henderson; F. G. F. Gibb; K. A. Foland Abstract Reinvestigation of the top 25 m of the 165 m thick Shiant Isles Main Sill requires reinterpretation of its internal structure, especially of the last unit emplaced – the granular olivine picro-dolerite. New mineral analyses allowere...

...H. I. Drever Abstract Investigation of Eilean Mhuire, the most easterly island of the Shiant isles, off the west coast of Scotland, shows the presence of but one sill, which is thought to be the downfaulted top of the crinanite-picrite sill of Garbh Eilean-Eilean an Tighe. Rhythmic layering...

...R. J. Murray Abstract The reinvestigation of the rocks of the Shiant isles, off the west coast of Scotland, which began with a study of the olivines, now continues with the clinopyroxenes. Optical and chemical data are given for six specimens from the picrite, picrodolerite, and crinanite...

...H. I. Drever Abstract A brief report on the Garbh Eilean-Eilean an Tighe sill in the Shiant isles off the west coast of Scotland, noting that the junction of picrite with overlying picrodolerite is very abrupt rather than transitional and that the picrite layer does not maintain an even level...

...R. Johnston Abstract The investigation of the olivines in the picrite, picrodolerite, and crinanite of the Garbh Eilean sill is part of a research program on the geochemistry and petrology of the rocks of the Shiant isles, situated 20 miles off the west coast of Scotland. Optical and chemical work...

... of average particle diameter is illustrated firstly with a consideration of the accumulation of olivine phenocrysts on the floor of the 135 m thick picrodolerite/crinanite unit of the Shiant Isles Main Sill. We show that the 45 m thick crystal pile on the sill floor could have formed by crystal settling...

... of this age crop out from as far north as the Shiant Isles in The Minch, east of the Isle of Harris, to the southern coast of Mull ( Morton & Hudson 1995 ). Jurassic sediments in the Inner Hebrides rest conformably on top of coarse-grained Triassic fluvial sediments which, in turn, unconformably overlie...
