Abstract

A research has been conducted to used magnetic method to know the subsurface structure around Sulawesi Sea. The data was collected using a set Proton Procession Magnetometer tools on Geomarine III ship with a total 22 trajectories. Processing data with IGRF correction to obtain total field magnetic anomaly. The result qualitative and quantitative interpretation is a variation of the total magnetic intensity  of -450 nT from the northeast toward the southwest of 110 nT. Variation of total anomaly magnetic intensity  is a parameter in determine the susceptibility rock have the effect to the subsurface geological structure around Sulawesi Sea. The results of geological effect are a subduction zone and a fault section. Magnetic suseptibility  of rocks on the subsurface around Sulawesi Sea is dominated by igneous rock  are  andesit and basalt rock, and metamophic rocks (k = 0,067833 SI – 0,065333 SI).
