Water content in natural eclogite and implication for water transport into the deep upper mantle
Abstract Infrared spectroscopy and ion micro-probe measurements showed that the major constituent minerals of eclogites from the Kokchetav massif, which have been subducted to ∼180 km depths, containExpand

Hydroxyl in clinopyroxene from the deep subducted crust: Evidence for H2O transport into the mantle
Abstract Clinopyroxenes in eclogites from the deep subducted crust in the Kokchetav, Kazakhstan, ultrahigh- pressure metamorphic terrane were found by infrared spectroscopy to contain up to 3020 ppmExpand

Determination of molar absorptivity of IR fundamental OH-stretching vibration in rhyolitic glasses
Abstract Molar absorptivity of the infrared (IR) fundamental OH-stretching vibration band at 3550 cm-1 was determined for rhyolitic glasses. Five obsidian samples, unheated and heated at 500-700 °CExpand
