eclogite उदाहरण वाक्य

Antigorite Serpentine is another important water bearing phase that breaks down at eclogite facies conditions.
Plagioclase is not stable in eclogite.
Xenoliths of eclogite occur in kimberlite pipes of Africa, Russia, Canada, and elsewhere.
Likewise, partial melting of eclogite has been modeled to produce tonalite-trondhjemite-granodiorite melts.
Eclogite, a rock similar to basalt in composition, is composed primarily of sodic clinopyroxene and garnet.

It also occurs in eclogite xenoliths from kimberlite as well as in crustal rocks metamorphosed at high pressures.
Lower pressure, normally contact metamorphism produces albite-epidote hornfels while higher pressures at great depth produces eclogite.
Transition into the eclogite facies is proposed to be the source of earthquakes at depths greater than 70 km.
The eclogite melt may then react with enclosing peridotite to produce pyroxenite, which in turn melts to produce basalt.
Commonly, only a few eclogite enclaves or UHP minerals reveal that the entire terrain was subducted to mantle depths.
