Rb–Sr and Sm–Nd isotopic compositions, U-Pb Age and Petrogenesis of Khajeh Mourad Paleo-Tethys Leucogranite, Mashhad, Iran
سال: 2011
خلاصه:
. 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...
