Case study

The relatively obvious magnetic anomaly section in the survey line is basically consistent with the abnormal range of apparent resistivity and apparent amplitude frequency in the induced polarization. The two verify each other. Combined with the results of the measurement of the physical properties of the main rocks (ores) in the study area, it is speculated that the anomaly is a mineral-induced anomaly caused by magnetite-bearing skarn or iron (zinc) ore body.

The results of high-precision magnetic profile measurements show that there is a relatively obvious magnetic anomaly area near the entire profile. Although the overall magnetic anomaly value is small and the magnetic anomaly range is narrow, the anomaly morphology is regular and the curve is approximately equiaxial. Therefore, it is preliminarily speculated that there is a certain degree of magnetite mineralization in this area.
