A correlation between hydroxyl vibrations under compression and anharmonicity: glaucophane as a test case
The infrared hydroxyl bands and first hydroxyl combination bands of glaucophane are characterized under pressure. In this weakly hydrogen-bonded...

Syn-exhumation metasomatic glaucophane-phengite-quartz veins formed at moderate pressures: exploring the control of fO2 and bulk composition on nominally HP metamorphic assemblages
Veins composed of glaucophane + phengite + quartz cross-cut the high pressure-low temperature (HP-LT) Cycladic Blueschist Unit (CBU) of southern...

Fluid evolution during burial and exhumation of the Tso Morari UHP complex, NW India: Constraints from mineralogy, geochemistry, and thermodynamic modeling
The Tso Morari terrane within the Himalayan orogenic belt underwent ultrahigh-pressure (UHP) coesite-eclogite metamorphism due to northward...

Age and Thermal History of Eclogites from Tulepsai Complex, Eastern Mugodzhar Range (Western Kazakhstan)
AbstractLenses of eclogites (the Tulepsai complex) that formed at the peak of metamorphism at P = 15 kbar and T = 700–750°C and experienced...

The behavior of Li and B isotopes in high-T and low-T eclogites enclosed by phengite schists
Subduction zones are critical sites for recycling of Li and B into the mantle. The way of redistribution of Li and B and their isotopes in subduction...
