At one locality near or at the lower margin of the main Shiant Isles sill there are contacts with Jurassic marl. Immediately adjacent to the highest of these contacts there is clear evidence of an endogenous reaction—Mg-olivine→ titanaugite. Zeolites tend to be concentrated near the contacts with marl and there is some evidence that teschenitic rock can result from exogenous reactions within the marl. An unusual degree of variability in the textural relations of olivine and augite with… Expand

The petrology of the Dippin sill, Isle of Arran
Synopsis The Dippin sill, which is emplaced into the Triassic sediments of SE Arran, is a basic alkaline intrusion of Tertiary age within which four main rock types have been identified. ExaminationExpand
Igneous stratigraphy and internal structure of the Little Minch Sill Complex, Trotternish Peninsula, northern Skye, Scotland
Detailed sampling of the Little Minch Sill Complex reveals that it is composed of both single and multiple sills. These are formed of three main, genetically related units: picrite, picrodolerite andExpand
Chemistry of the Shiant Isles Main Sill, NW Scotland, and Wider Implications for the Petrogenesis of Mafic Sills
Major and trace element data for the Tertiary, Shiant Isles Main Sill, NW Scotland, are used to discuss its complex internal differentiation. Vertical sections through the sill exhibit sharp breaksExpand
The Shiant Isles Main Sill: structure and mineral fractionation trends
Abstract The Shiant Isles Main Sill, of Tertiary age, is a classic example of a composite, differentiated alkaline basic sill. The first unit to be intruded was a 2 m thick olivine teschenite whichExpand
The Petrology of a Teschenite Sill at Landywood, Staffordshire
A basic igneous sill occurring in the coal seams at Landywood, England, has been studied by means of cores from five boreholes. The sill was encountered at depths between 355 and 710 feet and variesExpand
The Droimchogaidh sill, Connacht, Ireland
The Droimchogaidh sill, south-central Mayo, is sheeted at high-level in the Ordovician sedimentary pile of the South Mayo Trough. This association now lies raised on the eastern fringe of theExpand
Crystal settling and convection in the Shiant Isles Main Sill
While the PCU is unusual in being underlain by an earlier, still hot, intrusion that would have enhanced any driving force for convection, it is concluded from comparison with microstructures in other sills that convection is likely in tabular bodies >100 m thickness. Expand
Geological Results of Four Expeditions to Ubekendt Ejland, West Greenland
Outlines petrological discoveries made in 1938, 1939, 1950 and 1957 by British expeditions to this island in the Umanak Fjord region: an abundance of magnesia-and lime-rich intrusions and lavas; aExpand
Mean grain diameters from thin sections: matching the average to the problem
Abstract It is common practice to estimate a mean diameter for spherical or sub-spherical particles or vesicles in a rock by multiplying the average diameter of the approximately circularExpand

The ultrabasic rocks of Rhum were re-mapped over an area of 3 square miles, including Hallival and Askival, the highest mountains of the island, to reconsider its manner of origin in the light of modern petrological research, especially recent work on layered intrusions. Expand
XXII.—The Petrology of Picritic Rocks in Minor Intrusions—a Hebridean Group.
The results are presented of a detailed petrological reconnaissance of a group of picritic minor intrusions in the Hebrides. A substantial amount of new factual data is subjected to a unifiedExpand
The alkalic rocks of the Morotu district occur as sheets, laccoliths, and dikes in the Tertiary formations and are probably Pliocene. The rocks vary from dolerite, the most abundant, throughExpand
Geology of Inchcolm
In his classic paper on the igneous geology of the Forth area,1 Sir Archibald Geikie drew attention to the occurrence of picrite on the island of Inchcolm. And as a locality for picrite the islandExpand
The clinopyroxenes of the Garbh Eilean sill, Shiant isles
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 areExpand
The Term “Crinanite”
The name crinanite was given in 1911 by Sir John Flett to a suite of N.W. analcite-dolerite dykes occurring in a fairly extensive district in Argyllshire of which Loch Crinan is the centre. AExpand
The Olivines of the Garbh Eilean Sill, Shiant Isles
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 ShiantExpand
A Note on the Field Relations of the Shiant Isles' Picrite
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 thanExpand
