Abstract
The research area is at UTM 624399 – 625558 and UTM 9991175 – 9992510 with an IGRF value of 42800, inclination -150 and declination -0,030. Geographically, it is in the East and South-East of Talamau Mountain range. Regionally, this research area is controlled by convergent tectonic evolution around the mountain of Sumatera Island, belonging to surface arch zone and magmatic arch from Sumatera tectonic formation, in spite of the region bassist of disseminating magmatic quarter. It means that the research area has the potential for the existence of active volcano which produced lava containing iron. The iron ore of research area is produced by the Talamau Mountain range. It was formed at epoch quarter (Holosen-Pleistosen) from compiler rocks, like volcano rock, basalan-andesite-desit. The declination conducted by making 2D and 3D magnetic modeling methods. The results of 2D and 3D modeling are shown by iron ore in three places, A, B and C, with depth of 60 metres. Susceptibility range at 0,007 cgs (103 SI) with compiler rocks, that is granite, andesite-basalt, desite combined with iron ore.
