| 英文摘要 | Weiya V-Ti-magnetite deposit in Eastern Tianshan is the biggest one in North Xinjiang which the host rock belongs to a set of partial to alkalic mafic-ultramafic complex. Composition of main rock-forming minerals such as olivine, pyroxene, amphibole, biotite and plagioclase is in accord with that of ferruginous mafic-ultramafic rocks. Pyroxene, amphibole and biotite distinctly are Ti-rich, and the Ti and Fe contents commonly enrich in early stage rocks ( e. g. pyrolite and olivine gabbro). LA-lCPMS isotopic dating of zircon from gabbro is 236 +/- 3Ma which means the diagenetic age of Middle Triassic and represents an end stage of post-collisional mineralization. The Sr-Nd isotope of the host mafic-ultramafic complex is characterized by identically positive epsilon(Nd) (t) value and lower (Sr-87/Sr-86)(i) value, which suggests that the magma might be derived from mantle but mixing into continental crust material during magma moving up. |
