In order to utilize the horizontal components' information effectively in fixed TEM data interpretation, the authors conducted some simulations of three-components under different conditions and revealed that horizontal components have the characteristics of pointing to the ground projection center and relating to the attitude of the anomalous body. On such a basis, the authors made an interpretation of field data with horizontal components' characteristics and compared the results of horizontal components' qualitative interpretation with the results of z components' quantitative interpretation. It is indicated that their interpretation results are consistent with each other, the combined interpretation of the three-component overcomes the limitation of single component, and ensures the reliability of the inversion results.
