Abstract

Abstract

Using the marine self-potential method could explore the position and size of the seafloor hydrothermal polymetallic sulfide ore body. In the practical marine investigation, we could use the horizontal and vertical measurements. Here we used the numerical simulation method to analyze the detection effection of these two measuring ways. The analysis result indicates that vertical measurements could get a bigger anomaly than horizontal measurements. And the lateral resolution of vertical measurements is higher than horizontal. While vertical observation system's electrode is more close to the seafloor and have bigger operating risk than horizontal measurements. We need choose applicable detection system and observation way according to actual requirements. In the actual detection, there will be an angle between the electrodes and the horizontal direction. It will lead to a change of anomalies. We need to notice it in the data processing and interpretation. It can provide us with some reference about the marine exploration of the seafloor polymetallic sulfide.
