...B. Bagiński; P. Dzierżanowski; R. Macdonald; B. G. J. Upton Abstract The composite Eskdalemuir dyke was formed by the intrusion of rhyolitic magma into partly crystallized basaltic magma, the proportion of the silicic component increasing towards the dyke centre. The less silicic parts were...

...R. Macdonald; B. Bagiński; B. G. J. Upton; P. Dzierżanowski; W. Marshall-Roberts Abstract The Palaeogene Eskdalemuir dyke, part of the Mull dyke swarm in the Southern Uplands of Scotland, is ∼60 km long and up to 40 m thick. Its southern tip is 230 km from the inferred source on Mull. The dyke...

Fig. 4. A model of the initial emplacement of the Eskdalemuir Dyke ( Macdonald et al . 2010 ). The zoned magma chamber underlies the Mull Central Complex. Excess magma pressure, perhaps due to recharge lower in the chamber by basaltic magma, ruptures the side-wall. Basalt magma was intruded

F ig . 7. BSE images to illustrate different zonation patterns in Eskdalemuir pyroxenes. ( a ) A heavily resorbed and zoned pigeonite phenocryst is discontinuously rimmed by augite. Some matrix crystals seem to be annealing to the phenocryst, e.g. in upper-right corner. Note the tendency of Fe-Ti
