Implications of compositions of plagioclase and olivine on the formation of the Panzhihua V-Ti magnetite deposit, Sichuan Province
斜长石和橄榄石成分对四川攀枝花钒钛磁铁矿床成因的指示意义

Mineral assemblages and associated textures in the low and middle part of the Panzhihua intrusion indicate that plagioclase, olivine and Fe-Ti oxides were crystallized at a similar temperature range. Thus, it is possible to estimate variation of temperature, oxygen fugacity (fO2) and magma composition during the formation of the magnetite gabbro and gabbro in different cycles of the Panzhihua layered intrusion by means of compositions of plagioclase and olivine. Electron microprobe data indicate that plagio...
