Interpretation of the subsurface rock layer structure model has been carried out using geomagnetic data in the Palu Valley. Geomagnetic data is obtained through field measurements using the Proton Precision Magnetometer. Modeling is done using total magnetic field intensity data. The research objective is to determine the geological structure and subsurface rock layers. The modeling results show that at the study site, there are four rock layers and several faults mapped in the western, central, and eastern parts of the study location. Based on the susceptibility value, the rock structure at the study site consists of granite and sedimentary rocks, but the types of sedimentary rocks are different. The layer on the surface consists of alluvium according to what is exposed in the field. The second layer is thought to be sandstone which extends in harmony with the rock above it from west to east. The third layer is in the form of sandy clay which extends from the central part to the east and is not aligned with the layer above it while the lowest layer consists of granite rocks that are faulted in the western and eastern parts of the study area.
