Granitoid melt inclusions in orogenic peridotite and the origin of garnet clinopyroxenite | Geology | GeoScienceWor

Granitic melt inclusions were found in layers of garnet clinopyroxenites from orogenic peridotites hosted in high-pressure felsic granulites of the Granulitgebirge, central Europe. The inclusions are both glassy and crystallized, and occur as clusters in the garnet.

Non‐silicate inclusions in garnet from an ultra‐deep orogenic peridotite - Van Roermund - 2000 - Geological Journal - Wiley Online Libra

Non‐silicate solid inclusions in garnet from ultra‐deep garnet peridotites, Otrøy, Western Gneiss Region, Norway, have been studied using light‐optical, scanning and analytical electron microscopic techniques. ...

Granitoid melt inclusions in orogenic peridotites and origin of garnet clinopy

Abstract Former melt inclusions have been identified for the first time in orogenic peridotites from two different locations in the Granulitgebirge, Bohemian Massif. The inclusions are between 5 and 20 µm in diameter, and can be either polycrystalline, i.e. nanogranitoids ...

(PDF) Granitoid melt inclusions in orogenic peridotites and origin of garnet clinopyroxenit

With less than two decades of activity, research on melt inclusions (MI) in crystals from rocks that have undergone crustal anatexis – migmatites and granulites – is a recent addition to crustal petrology and geochemistry. Studies on this subject started with glassy ...
