Petrography and mineral chemistry of amphibolitic fragments in the south of Nain Ophiolite skarns, Central Iran

N Shirdashtzadeh; G Torabi; R Samadi

Volume 26, Issue 102 , March 2017, , Pages 153-164

https://doi.org/10.22071/gsj.2017.44135

Abstract
  Some dark green fragments of amphibolites are found within skarns at the south of Nain Ophiolite at the northeast of Nain city. They are similar to ortho-amphibolites (metamorphosed basic rocks) of this ophiolite in hand specimen, but mineralogically they are composed of amphibole (magnesio-hornblende, ...  Read More

Petrography and Petrogenesis of Aplite- Pegmatite Dykes and Granitoids of Khajeh Morad (SE Mashhad, Iran)

R Samadi; N Sh; H Kawabata

Volume 25, Issue 97 , December 2016, , Pages 49-60

https://doi.org/10.22071/gsj.2015.41351

Abstract
  Plutonic suite of Khajeh Morad at southeast of Mashhad includes granodiorites, which are cut across by younger aplite, granitic pegmatite dykes and monzogranites. Aplites are mineralogically including quartz, feldspar (albite to orthoclase and microcline), muscovite, and accessory minerals of garnet ...  Read More

Petrography, thermobarometry and geochemistry of Darreh Deh picrites (East of Nain ophiolitic mélange)

N Shirdashtzadeh; Gh Torabi; R Samadi; T Meisel; S.N Hussain Bokhari

Volume 25, Issue 98 , March 2016, , Pages 43-54

https://doi.org/10.22071/gsj.2016.41159

Abstract
  Picrites are seen within the mantle peridotites in the Darreh Deh area (in the east of Nain ophiolitic mélange). Based on petrography and mineral chemistry, these picrites are composed of olivine (chrysolite), clinopyroxene (diopside) and orthopyroxene (enstatite), showing a cumulate texture, ...  Read More

R Samadi; H Mirnejad; A.A Baharifar; S.J Sheikh Zakariaee

Volume 24, Issue 95 , June 2015, , Pages 75-86

https://doi.org/10.22071/gsj.2015.42384

Abstract
  The fibrolite garnet staurolite mica schist and staurolite garnet mica schist cropped out around the northwest of Khalaj, south of Mashhad in a SE_NW direction along the metamorphic complex of Kuh-e-Majuni. They have similar mineralogy and consist of quartz, annite, staurolite, almandine, muscovite, ...  Read More
