Weiya Fe-Ti-V oxide deposit is the biggest one in North Xinjiang, and lots of work on petrology, mineralogy, chronology and isotope geochemistry have been done by previous workers. However, the formation mechanism of massive ore type and banded type ore is not clear. Banded type Fe-Ti-V oxide ore not only is an important ore type in Weiya deposit (Wang et al., 2005, 2008), but also could give some clues in understanding the petrogenesis and metallogenesis of Fe-Ti-V oxide deposits. Therefore, systematic observation was carried on to explore the petrogenesis and metallogenesis process. At the same time, chemical composition of titanomagnetite in four types of rocks including two types of host rocks and two types of ore were analyzed to discuss the origin of FeTi-V oxide.
