Resolution of Each Component of CSAMT to Thin Layer

摘要

Although single component data collection of CSAMT has been put forward,no much research has been carried out on the resolution of each component to thin layer.It is urgently need for this study to provide guidance for single component data collection in practice.Based on the electromagnetic field of electric dipole,a three layered model is built up by adding a thin layer in an homogeneous half-space model.Models with resistivity,thickness and depth of the thin layer in simulated and the resolution of each component is also analyzed.The results show that each component has a better resolution to low resistivity thin layer.With the increase of thickness and decrease of depth of the thin layer,the resolution of different component increases.The x and z component have a better resolution,while the x and y component are not sensitive to longitudinal conductance.
