Garnet–clinopyroxene and clinopyroxene geothermobarometry of deep mantle and crust eclogites and peridotites

Lithos, 2008
Abstract Eclogite is one of the major types of xenoliths in kimberlite. An investigation of such xenoliths provides important constraints on the distribution of P and T within the upper mantle and its chemical composition. Garnet–clinopyroxene and clinopyroxene barometers are proposed for mantle eclogites and peridotites on the basis of CaTs ...

Geothermobarometry and Barrovian Metamorphism of Darjeeling-Mangpu Region, Eastern Himalaya

2016
Along the Darjeeling–Mangpu region, polyphase deformation and barrovian metamorphism has been delineated in relation to the Main Central Thrust (MCT). The different parageneses of pelitic rocks containing chlorite, muscovite, biotite, garnet, staurolite, kyanite, sillimanite, k-feldspar and plagioclase show various texture resulting by the continuous ...

Elastic geothermobarometry on multiple inclusions in a single host

2020
<p>The characterization of the pressure and temperature (P-T) histories of subducted rocks is of key importance to unravel geological processes at all scales. Conventional element-exchange geothermobarometers are challenged in ultra-high-pressure metamorphic terranes as the subduction temperatures may exceed their closure ...
