ژئوشیمی رادیو ایزوتوپ ها Rb–Sr و Sm–Nd، سن سنجی زیرکون U-Pb و تعیین منشأ لیکوگرانیت های خواجه مراد، مشهد، ایران
Biotite-muscovite leucogranite and associated pegmatite intruded meta-ophiolite and meta-flysch (the remnants of Paleo-Tethys) during collision of Turan plate with Iran plate. Four types of pegmatite dykes, crosscutting ...
Zircon U-Pb geochronology, Sr-Nd isotope analyses, and petrogenetic study of the Dehnow diorite and Kuhsangi granodiorite (Paleo-Tethys), NE Iran
The Paleo-Tethys ocean opened in Silurian time, and its subduction under the Turan plate started in the Late Devonian. By Late Triassic time (225 Ma), no Paleo-Tethys crust remained on the surface of the Iranian plate. ...
U-Pb zircon geochronology and Sr-Nd isotopic characteristic of late Neoproterozoic Bornaward granitoids (Taknar zone exotic block), Iran
The study area (Bornaward granite) is located in northeast of Iran (Khorasan Razavi province), about 280 km southwest of Mashhad city. Taknar zone is an exotic block, bordered by two major faults, Great Kavir fault (Drouneh) ...
Rb–Sr and Sm–Nd isotopic compositions, U-Pb Age and Petrogenesis of Khajeh Mourad Paleo-Tethys Leucogranite, Mashhad, Iran
Biotite-muscovite leucogranite and associated pegmatite intruded meta-ophiolite and meta-flysch (the remnants of Paleo-Tethys) during collision of Turan plate with Iran plate. Four types of pegmatite dykes, crosscutting ...
ژئوشیمی ایزوتوپ های Rb-Sr & Sm-Nd، سن سنجی زیرکون U-Pb و پتروژنز باتولیت گرانودیوریتی نجم آباد، گناباد
منطقه مورد مطالعه در شمال شرق ایران و جنوب شهر گناباد قرار گرفته است. این منطقه در شمال پهنه برشی دشت بیاض و نواحی جنوبی گسل درونه واقع شده است. حرکات این دو گسل بلوکی را بوجود آورده است که به دلیل موقعیت تکتونیکی و وجود ...
Review of Age, Rb-Sr Geochemistry and Petrogenesis of Jurassic to Quaternary Igneous rocks in Lut Block, Eastern Iran
The Lut Block (Eastern Iran) extends over 900 km in a north-south direction and is only 200 km wide in an east-west direction. It is confined by the Nayband fault and Shotori Range on the west. The eastern edge is bordered ...
