harzburgite meaning in Hindi

Examples

1. However early formed crystals in basaltic magma can also form harzburgite within the mantle.
2. The molten magma extracted from harzburgite may then erupt on the surface as basalt.
3. Garnet harzburgite xenoliths from kimberlites in South Africa have been particularly well-characterized.
4. Garnet-bearing harzburgite is much less common, found most commonly as xenoliths in kimberlite.
5. Harzburgite typically forms by the extraction of partial melts from the more pyroxene-rich peridotite called lherzolite.
6. The Lherz massif also contains harzburgite and dunite, as well as layers of spinel pyroxenite, garnet pyroxenite, and hornblendite.
7. Harzburgite is the most commonly found variety of peridotite in ophiolites, which are fragments of oceanic crust and the underlying oceanic Newfoundland.
8. Instead, basalts can be modelled as having been produced by 1 to 25 % partial melting of peridotite, such as harzburgite and lherzolite.
9. Harzburgite may also be found in some mantle lithosphere ( the upper mantle below continental crust ) exposed during the plate tectonic collision of continental plates.
10. Garnet-bearing harzburgite is found as xenoliths in some kimberlite pipes, which are found almost exclusively in ancient continental cratons of Archean or Paleoproterozoic age.
