Abstract Rheomorphic ignimbrite D (13.4 Ma, Upper Mogán Formation on Gran Canaria), a multiple flow–single cooling unit, is divided into four major structural zones that differ in fabric and finite strain of deformed pyroclasts. Their structural characteristics indicate contrasting deformation mechanisms during rheomorphic flow. The zones are: (a) a basal zone (vitrophyre) with pure uniaxial flattening perpendicular to the foliation; (b) an overlying shear zone characterized by asymmetric… 
Rheological controls on the emplacement of extremely high-grade ignimbrites
Extremely high-grade, lava-like welded ignimbrites are produced by many large explosive eruptions with volumes typically 101–103 km3. However, understanding of the physical properties of these
Emplacement and rheomorphic deformation of a large, lava-like rhyolitic ignimbrite: Grey's Landing, southern Idaho
The Miocene Grey9s Landing ignimbrite reaches 70 m thick and covers at least 400 km 2 in the central region of the Snake River Plain. It shows particularly intense welding and rheomorphic
The emplacement of a large, chemically zoned, rheomorphic, lava-like ignimbrite: the Sgurr of Eigg Pitchstone, NW Scotland
The Sgurr of Eigg Pitchstone on the Isle of Eigg, NW Scotland, is a crystal-rich, trachydacitic, partially vitrophyric rock, which has previously been interpreted both as a lava and as a sill. We
Flow banding in volcanic rocks: a record of multiplicative magma deformation
Banding in obsidian from Big Glass Mountain (BGM), Medicine Lake volcano, California, and Mayor Island (MI), New Zealand, provides a record with a 1/wavenumber power-spectral density and multifractal
Groundmass crystallisation and cooling rates of lava-like ignimbrites: the Grey’s Landing ignimbrite, southern Idaho, USA
Constraining magmatic and eruptive processes is key to understanding how volcanoes operate. However, reconstructing eruptive and pre-eruptive processes requires the ability to see through any
Relations between thermal history and secondary structures of ignimbrites exclusive of rheomorphism
Newly calculated model density profiles of ignimbrites also provide model thermal histories, which serve as a framework to help analyze the development of cooling joints, devitrification textures,


Large-scale rheomorphic shear deformation in Miocene peralkaline ignimbrite E, Gran Canaria
Abstractthe single ignimbrite cooling unit E (average thickness, 28 m; volume, ca. 30 km3) forms the uppermost member of the Miocene Upper Mogán Formation on Gran Canaria. It is strongly chemically
Laminar Viscous Flowage Structures in Ash-Flow Tuffs from Gran Canaria, Canary Islands
At least $$100 km.^{3}$$ of trachytic and peralkaline soda rhyolitic ash flows were erupted during late Miocene to early Pliocene time from a source near the center of Gran Canaria, Canary Islands.
Compaction of the Bishop Tuff, California
The foliation in welded tuffs is defined by planar alignment of glass shards, platy crystals, and flattened pumice fragments. The textural features and interrelationships of these elements are
Chronostratigraphy of Gran Canaria
A chronostratigraphy of Miocene/Pliocene volcanism on Gran Canaria (Canary Islands) has been established by single- crystal 40Ar/39Ar laser dating of feldspar crystals from 58 samples of welded
Volcanological aspects of peralkaline silicic welded ash-flow tuffs
Peralkaline silicic welded ash-flow tuffs differ characteristically in a number of properties from most calc-alkaline welded tuffs, due to their generally lower viscosity and higher temperatures.For
Grain size variations in ignimbrites and implications for the transport of pyroclastic flows
Ignimbrite flow units commonly show reverse grading of large pumice clasts and normal grading of large lithic clasts. Ignimbrites show coarse-tail grading, in which particles beneath a critical
Mixing of rhyolite, trachyte and basalt magma erupted from a vertically and laterally zoned reservoir, composite flow P1, Gran Canaria
The 14.1 Ma composite welded ignimbrite P1 (45 km3 DRE) on Gran Canaria is compositionally zoned from a felsic lower part to a basaltic top. It is composed of four component magmas mixed in
Calculated Compaction Profiles of Rhyolitic Ash-Flow Tuffs
Compaction zones in ash-flow tuffs result from differential compaction of ash after emplacement. Ash compacts largely by viscous deformation, and the rate of compaction is therefore governed in part
Structural relaxation in silicate melts and non-Newtonian melt rheology in geologic processes
The timescale of structural relaxation in a silicate melt defines the transition from liquid (relaxed) to glassy (unrelaxed) behavior. Structural relaxation in silicate melts can be described by a
