Whole rock chemistry, dating and tectonomagmatic setting of metagabbros from Qotur area, NW-Iran

Mohammad Saadat; Robab Hajialioghli; Mohssen Moazzen

Volume 31, Issue 1 , June 2021, , Pages 71-84


  The Qotur metamorphic complex in west of Khoy is consist of various metamorphic rocks including of metabasites, metapelitic and meta-calcareous rocks and serpentinites. The metagabbros form main outcropping rocks in the area. Plagioclase and pyroxene are the main porphyroclasts of metagabbros. Epidote, ...  Read More

Investigate the partial melting process in Hornblend bearing migmatites with Ghar-Naz, northwestern Iran

haleh ghorbani; robab hajialioghli; mohsen moazzen

Volume 30, Issue 117 , December 2020, , Pages 25-38


  The Ghareh naz migmatites were formed as a result of partial melting of amphibolites under granulite facies conditions. Structeral, textural, mineralogical and geochemical evidence in the migmatites migmatites indicates their formation via partial melting during partial melting. The studied migmatites ...  Read More

Lamprophyre, mica pyroxenite, amphibolite and carbonate rocks occure as xenoliths within andesites. The main rock forming minerals for lamprophyre xenolith ...  Read More

Investigation on the physical and chemical conditions of the formation of hexagonal colored quartz crystals in Qohrud area based on petrographic evidence and fluid and solid inclusion studies

M. R. Rezapour; V. Simmonds; M. Moazzen; R. Hajialioghli

Volume 28, Issue 111 , May 2019, , Pages 95-104


  The Qohrud granitoid body of Miocene age is located 40 km SW Kashan, ranging in composition from granite through granodiorite to tonalite. Hydrothermal activities following the magma intrusion have brought about formation of various coarse automorphic and colored quartz crystals within the fractures ...  Read More
