| Abstract: | Panzhihua is the famous area at vanadic-titanomagnetite. The ore body exists in basic layered intrusion. The author has collected samples in high density during the fidld study, measured and dealt with the compositions, structure state, elongation coefficient and twin types of plagioclase-main rockforming mineral by means of mathematical statistics. According to the optical character of plagioclase the relationship between mineralization and the basic layered rock forming process is discussed. The possibility of guiding the search after ore deposit is indicated. |
