The nature of zircon in the Volkovsky massif gabbro (Middle Urals): the age problem and geochronological consequences

Литосфера, 2017
The article presents new isotope-geochemical data on zircon from gabbronorites of the Volkovsky massif in the Middle Urals. The massif is a complex combination of different rock associations - from ultramafic rocks to syenites and quartz diorites, whose ...

Pre-1.91 Ga deformation and metamorphism in the Palaeoproterozoic Vammala Migmatite Belt, southern Finland, and implications for Svecofennian tectonics [PDF]

Bulletin of the Geological Society of Finland, 2004
A metamorphic event in the Vammala Migmatite Belt (VMB) at ~1.92 Ga, revealed by SHRIMP U-Pb analyses of both zircon overgrowths and monazite, is interpreted as post-depositional and is correlated with the development of the early high-grade schistosity.

High-Pressure Induced Structural Phase Transition in CaCrO4: Evidence from Raman Scattering Studies

, 2005
Raman spectroscopic studies have been carried out on CaCrO4 under pressure up to 26GPa at ambient temperature. The Raman spectra showed CaCrO4 experienced a continuous structural phase transition started at near 6GPa, and finished at about 10GPa.

Fluids in the Siilinjärvi carbonatite complex, eastern Finland: Fluid inclusion evidence for the formation conditions of zircon and apatite [PDF]

Bulletin of the Geological Society of Finland, 1995
In the studied zircon and apatite crystals, data recorded two different compositional types of fluid inclusions: Type 1 H2O-CO2 low salinity inclusions (XCO2 = 0.42 to 0.87; XNaCl = 0.001 to 0.005) with bulk densities of 0.73 to 0.87 g/cm3, and Type 2 ...

Thermoluminescence of zircon: a kinetic model [PDF]

Journal of Physics: Condensed Matter, 2003
The mineral zircon, ZrSiO4, belongs to a class of promising materials for geochronometry by means of thermoluminescence (TL) dating. The development of a reliable and reproducible method for TL dating with zircon requires detailed knowledge of the processes taking place during exposure to ionizing radiation, long-term storage, annealing at moderate ...

Characterization of the zircon Ce anomaly for estimation of oxidation state of magmas: a revised Ce/Ce* method

Mineralogy and Petrology, 2019
As a proxy of magmatic oxidation state, the accurate characterization of the Ce anomaly of zircon is of great significance since it can give important information for provenance studies of rocks as well as for exploration of intrusion-related mineral ...

Synergistic Co‐Pyrolysis of Tannery Sludge and Oyster Shells for Enhanced Chromium Speciation Transformation and Recovery Efficiency

CleanMat, EarlyView.
Oyster shell (OS) as a sustainable calcium source for chromium recovery from tannery sludge via co‐pyrolysis. OS outperformed CaCO3, achieving > 95% Cr recovery, attributed to its organic matrix proteins enhancing adsorption and phase conversion. The oxidation of tannery sludge Cr(III) to Cr(VI) improved recyclability, aligning with circular economy ...

Diagenetic processes controlled by volcanic detritus of the Lower‐Middle Permian Shanxi and Shihezi sandstone formations, North Ordos Basin, China

The Depositional Record, EarlyView.
Comparisons of Lower‐Middle Permian Shanxi and Lower Shihezi formations from the North Ordos Basin reveal that different types and percentages of volcanic detritus induced by active magmatic cycles can significantly change diagenetic evolution and favourable reservoirs.
