Rb–Sr and Sm–Nd isotopic compositions, U-Pb Age and Petrogenesis of Khajeh Mourad Paleo-Tethys Leucogranite, Mashhad, Iran
Year: 2011
Abstract:
. Magnetic susceptibility of biotite muscovite leucogranite and aplite granite are between than 0-5 × 10-5 and the ratio of ferric to ferrous ratio (< 0.35), therefore they are classified as belonging to the ilmenite-series (reduced type). The total REEs...
Zircon U-Pb geochronology, Sr-Nd isotope analyses, and petrogenetic study of the Dehnow diorite and Kuhsangi granodiorite (Paleo-Tethys), NE Iran
Year: 2010
Abstract:
). The granodiorite and diorite have magnetic susceptibilities of between 5 × 10–5 and 20 × 10–5 (SI units) and therefore are classified as belonging to the ilmenite series of reduced-type granitoids. Chemically, the Dehnow diorite and Kuhsangi granodiorite...
