Ilmenite-rich titanium orebody was newly discovered from anorthositic mass distributed in the Handong-gun, Kyungsangnam-do. The orebody ranges from 2m to 30m in width and runs at least 14Km. The anorthositic mass may be zoned whose boundaries run parallel to almost north-south direction on the basis of abundance of mafic minerals and diagnostic texture observed. The titanium orebody is nearly conformable to the lithological zonation boundaries, striking N30°E-N20°W and dipping vertical to 50°-70°NW or SW. Gravity, resistivity and seismic exploration have been performed over the area. Gravity anomaly near the orebody varies from 115mgal to 122mgal, showing higher value than those of the surroundings of anorthositic rocks. Resistivity sounding indicates the value significantly lower than that of the surroundings. However, not special indication has been obtained from the seismic method for the orebody. All the geophy sical data obtained thus far correspond well with those observed on the surface and support the possibility that the orebody continues downward at least 150m below the research position.
