Abstract
Volumetric determining in mining prospect encounters certain biases. Resistivity imaging was comprehended to determine the resistivity distribution of the andesite body. Inversion is used to characterize a subsurface property upon the geological condition. Inversion data are transformed into model parameters which could explain the possible subsurface properties that may cause the data be obtained based on the acceptable forward formulation (Martakusumah and Srigutomo, 2015). Marquadt and Occam inversion are non-linear inversions with a linear approximation. Both of inversions are used on the resistivity data resulting a comparative resistivity model. The result from Marquadt inversion suites more with the geological condition, in contrary with Occam inversion. Andesite body identified as a high resistivity value ranging 400 – 2000 Ω.m. Marquadt inversion portray intrusion shaped andesite with a volumetric reaching 9,987 x 10 .
