Abstract. The Northern Marginal Zone of the Rum Central Igneous Complex in NW Scotland represents part of the early, felsic phase of the volcano. The marginal zone is a relic of the early caldera floor and the infilling of sedimentary and igneous rocks. Its formation has been explored through field examination of the ring fracture system of the Complex and its pyroclastic and epiclastic intracaldera facies. A sequence of magmatic tumescence and chamber growth caused initial doming, followed by… Expand
Felsites and breccias in the Northern Marginal Zone of the Rum Central Complex: changing views, c. 1900–2000
SUMMARY As in several other parts of the British Tertiary Igneous Province, breccias and felsite sheets are closely associated on the Isle of Rum. This association has been described and interpretedExpand
Collapse mechanism of the Paleogene Sakurae cauldron, SW Japan
The Paleogene Sakurae cauldron of SW Japan is characterized by a nested structure with a polygonal outline (21×13 km2) including a circular collapsed part (5 km in diameter). Total thickness of theExpand
The formation and evolution of the Central Arran Igneous Complex
The Central Arran Igneous Complex – a system of intrusive and pyroclastic volcanic rocks – is one of the least understood onshore ‘central complexes’ of the British Palaeogene Igneous ProvinceExpand
Pre-eruptive magma mixing in ash-flow deposits of the Tertiary Rum Igneous Centre, Scotland
The Northern Marginal Zone of the Rum Igneous Centre is a remnant of an early caldera and its infill. It is composed of intra-caldera breccias and various small-volume pyroclastic deposits, overlainExpand
Fault-Controlled Magma Ascent Recorded in the Central Series of the Rum Layered Intrusion, NW Scotland
The Palaeogene layered ultrabasic intrusion of the Isle of Rum forms the hearth of the Rum Igneous Centre in NW-Scotland. The regional Long Loch Fault, which is widely held to represent the feederExpand
Early mafic magmatism and crustal anatexis on the Isle of Rum: evidence from the Am Màm intrusion breccia
Abstract The Rum Igneous Centre comprises two early marginal felsic complexes (the Northern Marginal Zone and the Southern Mountains Zone), along with the later central ultrabasic–basic layeredExpand
How summit calderas collapse on basaltic volcanoes: New insights from the April 2007 caldera collapse of Piton de la Fournaise volcano
In April 2007, Piton de la Fournaise volcano experienced a caldera collapse during its largest historical eruption. We present here a structural analysis both of the caldera and the surrounding area,Expand
The peridotite plugs of Rum: Crystal settling and fabric development in magma conduits
The Rum Igneous Complex contains numerous circular to elongate exposures of peridotite cumulates within the layered series and the country rock. The extent of thermal effects on quartzo-feldspathicExpand
Intrusive history of the Slieve Gullion ring dyke, Ireland: implications for the internal structure of silicic sub-caldera magma chambers
Abstract The Palaeogene Slieve Gullion Igneous Complex comprises a layered central intrusion surrounded by a slightly older ring dyke. The ring dyke contains two major intrusive rock types. About 70%Expand
A proximal record of caldera-forming eruptions: the stratigraphy, eruptive history and collapse of the Palaeogene Arran caldera, western Scotland
Caldera-forming volcanic eruptions are among the most dangerous, and can generate extensive pyroclastic deposits and deliver ash into global atmospheric circulation systems. As calderas collapse, theExpand
