Pelitic hornfelses within the inner thermal aureole of the Etive igneous complex underwent limited partial melting, generating agmatic micro-stromatic migmatites. In this study, observed volume proportions of vein leucosomes in the migmatites are com

Experimental deformation of hot-pressed powders of lizardite serpentinite was carried out to study the effect of the dehydration reaction to olivine + talc + water under controlled pore water pressure. Use of a porous aggregate ensured free movement

The Karakoram fault shows a full range of fault rocks from ductile (deformation by intracrystalline plasticity) mylonites to low temperature brittle fault rocks along the trace of the fault in the Eastern Karakoram, Ladakh, NW India. The Karakoram fa

A series of dehydration experiments was carried out on both intact rock and cold-pressed powdered samples of serpentinite at temperatures in the range 535-610 � C, 100-170 � C above the onset of the breakdown temperature of 435 � C. Pore water

New geological mapping has led to a new interpretation of the large-scale superimposed folding in the upper part of the Ivrea-Verbano zone, Italian Alps. The region is widely held to represent an upended section through lower continental crust of nor

Layers of fine-grained muscovite were hot-pressed then sheared between alumina sliders to shear strains up to 2, at temperatures between 300 and 700 °C, confining pressures of 206 MPa and various pore water pressures. High pore water pressures helpe

Grain size-sensitive flow may be of particular importance in the flow of rocks in natural high-strain zones. Hot-pressed aggregates of synthetic, ultrafine-grained Brazilian quartz of nominal grain sizes 0.4, 1.3 and 4.5 μm were deformed at 300 MPa

Samples of synthetic, ultrafine-grained quartzite were prepared by hot-pressing aggregates of crushed, clear Brazilian quartz of mean grain size 0.4 μm at 300 MPa and 1373 and 1473 K. The samples displayed rapid grain-growth to ca. 12–20 μm with

When deformed together in nature, calcite rocks invariably appear weaker and more ductile than quartz rocks. This can be reconciled with experimental flow data only by taking into account grain-size-sensitive (GSS) flow in calcite rocks, which is pre
