Paper Abstract

In order to search for new prospect areas of iron ore resources in Isabela, the Philippines, the comprehensive technologies of remote sensing and high precision magnetic method are applied, which can combine the macro-characteristics of remote sensing with the detailed detection of geophysics. Remote sensing geological characteristics, including the linear structures, the ring structures and the linear-ring structure combination are analyzed in emphasis. In addition, the high-precision magnetic measurement is carried out in the geophysical survey area. At last, by analyzing the distribution of the inferred magnetic body in the geophysical survey area and the relationship between the linear-ring structure combination and the two known iron ore occurrences, the prospecting model is established. In the study area, northwest or northeast trending faults combined with ring structures are beneficial to the mineralization, which is verified in the known iron ore occurrences. Five target areas which have similar metallogenic conditions as known iron ore occurrences are predicted depending on the model. It is proposed that further work should be done within 8 kilometers along the northeast side of the northwest trending piedmont regional fault and those hydrothermal deposits which correlate with intermediate intrusive rocks should be put emphasis upon.
