Titanite (CaTiSiO5) is a naturally occurring silicate phase, recently recognised as potential material for immobilization of nuclear wastes, high-end ceramic lining and optical device development. The undergoes pressure-induced structural transition (P21/c to C2/c) at ~3.5 GPa, which we confirm from density function perturbation theory. Using first principles calculations pressure-dependent par...

The authors regret to have inadvertently supplied an erroneous version of the data table displaying recalculated titanite analyses.

Abstract Titanite U–Pb geochronology is a promising tool to date high-temperature tectonic processes, but the extent and mechanisms by which recrystallization resets titanite dates are poorly understood. This study combines dates, trace elements, zoning, microstructures directly deformation fluid-driven along Coast shear zone (BC, Canada). Twenty grains from deformed calc-silicate gneiss yield ...

The Vathi porphyry Cu-Au±Mo deposit is located in the Kilkis ore district, northern Greece. Hydrothermally altered and mineralized samples of latite quartz monzonite are enriched with numerous rare critical metals. present study focuses on bulk geochemistry mineral chemistry pyrite, chalcopyrite, magnetite, titanite. Pyrite chalcopyrite most abundant minerals at related to potassic, propylitic,...

This study reassesses the development of compositional layering during the growth of granitic plutons, with emphasis on fractional crystallization and its interaction with both injection and inflationrelated deformation. The Dolbel batholith (SW Niger) consists of 14, kilometre-sized plutons emplaced by pulsed magma inputs. Each pluton has a coarse-grained core and a peripheral layered series. ...

The metamorphic reworking of mineralized pegmatites during orogenesis remains unclear, making the genesis and tectonomagmatic significance pegmatite mineralization obscure. This study demonstrates multiple utilities titanite geochemistry in establishing Caledonian evolution world’s largest intra-plutonic Nb-Y-F Paleoproterozoic host rocks Tysfjord, Northern Norway. A combination titanite-specif...

Modulation of resistance by an external magnetic field, i.e. magnetoresistance effect, has been a long-lived theme of research due to both fundamental science and device applications. Here we report colossal positive magnetoresistance (CPMR) (>30,000% at a temperature of 2 K and a magnetic field of 9 T) discovered in degenerate semiconducting strontium titanite (SrTiO3) single crystals capped w...

Marbles containing high-pressure mineral assemblage was found from the Sanandaj-Sirjan metamorphic belt in the Nahavand area in western Iran.  The high-pressure marbles occur as small bodies or lenses within pelitic schist layers and show compositional banding of carbonate- and silicate- rich bands.  Textural analysis revealed two metamorphic stages.  The early stage is testified by relicts of ...
