Sr-Nd isotopic geochemistry and 40Ar-39Ar and Rb-Sr dating of Ghoshchi A2-type granites, N Uromiyeh, NW Iran

Sh. Shahabi; H. Shafaii Moghadam; Gh. Ghorbani

Volume 27, Issue 107 , June 2018, , Pages 27-40


  The Ghoshchi granitic rocks are located in at north of Uromiyeh city and are mainly composed of alkali-feldspar granites, granites and aplitic dykes. These samples belong to calc-alkaline to shoshonitic series and show Fe enrichment and are classified as A-type granites. Ghoshchi granites have high K2O+Na2O, ...  Read More

Zircon U-Pb geochronology and Lu- Hf and O isotopes of the metamorphosed intrusive rocks from SW Salmas

F Kozekoulani; M Rahgoshay; H Shafaii Moghadam

Volume 26, Issue 102 , March 2017, , Pages 303-312


  Intrusive rocks from SW Salmas include mafic-intermediate and acidic rocks, which occur in the border of Sanandaj-Sirjan and Urmia-Dokhtar zones in Northwest of Iran. The mafic-intermediate rocks comprise metadiorite and metagabbros that are the oldest rocks in the region. The acidic rocks include metagranite ...  Read More

Geochemistry and Petrogenesis of Andesitic-Basaltic Series in Siah-Cheshmeh Ophiolite, NW of Khoy

M. Poormohsen; M. Rahgoshay; I. Azadi; H. Shafaii Moghadam

Volume 20, Issue 77 , January 2010, , Pages 131-136


  The Siah-Cheshmeh ophiolites at the north-northwest part of the Khoy ophiolites show a dismembered pile of metamorphic units, mantle sequence, and basaltic-andesitic lavas associated with Late Cretaceous pelagic limestones and cherts.  The basaltic-andesitic lavas can be divided into alkaline and ...  Read More

The Geochemistry and Petrology of Mantle Sequence in the Nain Ophiolite

M. Rahgoshay; J. Mehdipour Ghazi; H. Shafaii Moghadam

Volume 18, Issue 71 , January 2009, , Pages 31-44


  Peridotites (Cpx-bearing harzburgites, lherzolites, wherlites and dunites) associated with pegmatite gabbros, gabbro impregnations, gabbroic-diabasic dikes, pyroxenites and websterites are the main constituents of the mantle sequence in the Nain ophioliote assemblage. Petrographic and geochemical studies ...  Read More

Geochemistry and Eruptive Environment of the Mafic Rock Series in the Balvard-Baft Ophiolites

H. Shafaii Moghadam; M. Rahgoshay; H. Whitechurch; I. Monsef; A. Soltan Mohamadi

Volume 18, Issue 72 , January 2009, , Pages 155-160


  Basalts, gabbros, tuffs, diabasic dikes, agglomerates and breccias and the rock fragments of breccias are the main mafic constituents of the Balvard-Baft ophiolites. Geochemical signatures of these rocks reveal depletion in HFSE and enrichment in LILE and simultaneous occurrence of island-arc tholeiitic ...  Read More

Microstructural Evolution of the Mantle Lithosphere in the Khoy Ophiolites - NW of Iran

M. Rahgoshay; I. Monsef; H. Shafaii Moghadam; M. Mohajjel

Volume 16, Issue 63 , March 2007, , Pages 2-17


  Petrofabric, structural and geochemical study of the ultramafic tectonites in the Khoy ophiolitic complex suggest that these tectonites including low-temperature NW-SE shear zones cut the high-temperature to medium-temperature NE-SW mantle flow direction. Microstructures in these tectonites, record a ...  Read More
