Three-component response of transient electromagnetic method

Abstract

Abstract Based on the three-component TEM forward simulation, through varying the dip angle and strike of underground target, changing overburden conditions, three-component response characteristics were analyzed. According to the three-component responses, the geometric features (the position, size, and occurrence) of anomalous body can be determined. The extreme points of the X and Y component response curves reflect the boundary of the tabular body; the zero-crossing point of the curves corresponds to the center of the tabular body. According to the range size of X and Y component curves, and the position of extreme points and zero-crossing points, the dip angle and extension direction and the center of the tabular body can be determined.
