The basis of this proposal is to experimentally determine high pressure-temperature melting phase relations along two critical regions of the melting curve, plagioclase-spinel lherzolite
and spinel-garnet lherzolite
2006): Trace element partitioning between mica-and amphibole-bearing garnet lherzolite
and hydrous basanitic melt: 1.
The peridotite unit rocks are the most altered part of Noorabad ophiolite including dunite, harzburgite and lherzolite
The foliated peridotite sequence is harzburgite-type (Nicolas, 1989) although minor lherzolite
has also been reported from the basal section of the mantle sequence (Mahmood et al.

Melting of phlogopite-bearing peridotite produces potassic rather than sodic magmas, but melting of amphibole- and clinopyroxene-bearing lherzolite
yields magmas with low CaO/[Al.
The dyke contains abundant large (up to at least 9 cm) phenocrysts and xenocrysts in addition to a wide variety of xenoliths that include granulite, dunite, lherzolite
, werhlite, harzburgite, and pyroxene peridotite (Ross et al.
They correspond to the Lherzolite
Ophiolite Type (LOT) as defined by Nicolas (1989).
The dominant rock-type of the Balmuccia peridotite massif is a medium- to coarse-grained, porphyroclastic spinel lherzolite
Diamonds are known to occur in three peridotite subtypes: dunite (90% olivine), harzburgite (40-90% olivine, the rest orthopyroxene and garnet), and lherzolite
(at least 40% olivine, with orthopyroxene and clinopyroxene in a wide range of proportions, and minor garnet).
The Precambrian Ophiolits in north of Anarak are seen underneath the Precambrian-lower Cambrian metamorphics  and are of Harzburgite and partly lherzolite
accompanied with whom scattered masses of gabbro, Diabase, and plagiogranite are observed.
The harzburgite and dunite of the lower mantle section have often been referred to as depleted peridotite resulting from large degrees of partial melting from a lherzolite
parent and also that they are partly formed by the processes such as magma-mantle interaction.
