Research on Magnetic 3D Visualization Modeling Based on Wavelet Multiscale Analysis

3D visualization modeling is an important tool for improving geological understanding and displaying underground information. Mianleyang Triangle Area in Shaanxi Province is an important polymetallic ore concentration area in the south of Shaanxi Province. This area has complex geological conditions, developed structures, frequent magmatic activities, and obvious mineralization. The Jinzishan gold copper polymetallic mining area located in the area mostly sees Magnetite bearing breccia Serpentinite, which has obvious magnetic and electrical differences with the surrounding rock. This article uses wavelet multi-scale decomposition and power spectrum calculation on magnetic 3D data to calculate the field source depth of each order of detail anomalies. Using the Voxler platform, a 3D magnetic body model is established to infer the relative position of magma channels and ore bodies. Good results have been achieved through geological drilling verification.
