Opposing coils transient electromagnetic method (OCTEM) offers high resolution for shallow subsurface investigations, making it a potential tool for detecting bauxite layers. However, in laterite- covered terrains, the superparamagnetic response of the overburden masks the target response by superimposing a strong, long- decay signal onto the secondary transient field induced by eddy currents, significantly degrading detection resolution. To address the challenge of deep bauxite exploration in the Bailong Shujingcun ore block (Yunnan Fumin deposit, China), this study established a layered geological model based on local stratigraphy and statistical physical properties. This model integrates the resistivity characteristics of the bauxite layer, its host stratum, and the surrounding rocks. We conducted forward modeling to analyze the OCTEM response patterns with shallow superparamagnetic cover. Based on these patterns, a calibration and correction methodology was developed to suppress the superparamagnetic influence from the measured induced voltage. The corrected data were then inverted to recover the subsurface resistivity distribution. Comprehensive interpretation of 2D resistivity sections from two OCTEM profiles, integrated with an ore- prospecting model, successfully delineated the deep extension and distribution of the bauxite ore block. Drilling results subsequently confirmed these findings, verifying the accuracy of the approach. This study demonstrates that, with appropriate signal processing, OCTEM can be effectively applied for detecting bauxite layers in areas covered by superparamagnetic laterite.
