摘要：

A series of crystallization experiments have been carried out by using natural Emeishan Ti-rich hydrous basalts as starting materials at a pressure of 0.5 GPa and temperatures of 800-1 000 degrees C to constrain the origin of Fe-Ti-V oxide ore deposits. Our experimental results demonstrate that the sandwich- and trellis-type ilmenite lamellae in titanomagnetite of layered intrusions can be formed by the reaction of earlier crystallized ilmenite and the evolved parental magma. During evolution of parental basaltic magma, the Fe-Ti oxide should be composed of titanomagnetite+ilmenite in the earlier stage, but changed to titanomagnetite+titanomagnetite-ilmenite intergrowth +/- ilmenite at the later stage. Accordingly, the Panzhihua Fe-Ti oxide ores, which are mainly composed of titanomagnetite, should be formed earlier than the adjacent gabbro, in which titanomagnetite-ilmenite intergrowth is the major form of the Fe-Ti oxide.
