Abstract


Upward Continuation process to be done because he wanted to see how the boundary where the body of iron ore minerals, and Reducrion To The Pole was done because initally dipole magnetic anomalies, the process is carried out so that its response to the monopole magnetic area from 2D modeling results the model predicted the existence of iron ore minerals with susceptibility contrast amounted to 0.8585 cgs (103 SI), 1.0100 cgs (103 SI), 0,7100 cgs (103 SI) with thickness of about 25 until 50 meters which can be found at a depth of 25 meters. Which is the value of susceptibility contrast to 0.100 cgs (103 SI) to 0.122 cgs (103 SI) and a granite rock, iron ocide, pyrite, and tuff of which are associated eith the iron ore. Interpretation of results in 2D, 3D and regional geological information showed that the depth of the iron ore minerals associated with granitic rocks, iron oxides, pyrite, and iron tuff located at a depth of 15-30 meters.
