Multiphase solid inclusions within cumulus silicates,particularly olivine,in Fe-Ti oxide ores from the Lower Zone of the Baima intrusion,Emeishan large igneous province,SW China,have been identified for the first time using 2-D scanning electron microscope and 3-D high-resolution X-ray computed tomography.These inclusions are spherical to subspherical and range from 100 to 300μm in diameter.They are composed dominantly of titanomagnetite and ilmenite with minor apatite,hornblende,phlogopite and pyrrhotite.The titanomagnetite in the inclusions has low Cr contents(＜700 ppm)similar to the interstitial titanomagnetite,suggesting that these inclusions cannot be early crystallized mineral aggregates.
