Qualitative analysis using impedance is necessary in geological interpretation of real acoustic magnetotelluric(AMT)data with heavy fake structures in inversion results caused by strong static shift effects.But impedance itself would lose the veracity due to violent changing of three-dimensional topography or non-homogeneity of the shallow subsurface.This work studies how to remove the effects of topography and non-homogeneity from real AMT data,test the ability to recover the deep anomaly locations using this phase correction technique,and evaluate the its conribution to improve the reliability of geological interpretation.Using staggered grid finite difference MT modeling technology,we can compute two models′AMT responses with or without predefined anomalies.The background responses can be used as correction values to correct measured data.The high values of corrected impedance phase invariants correspond to the lowered resistivity,while the low values to rising resistivity.We do many inversions in different parameters and modes of anomaly model synthetic data both in 1D and 2D.The anomaly locations would be in the places which have high coherence between inversion results and corrected impedance phase invariant,meanwhile the inconsistency of them shows fake structures influenced by static shift.It is more important to obey the coherency principle of inversion result and corrected impedance phase invariant when interpreting real data whatever inversion technology(1Dor 2D)is used.Both the model data and real data are related with a kimberlitic exploration project in southwest China.The corrected impedance phase invariant recovered the horizontal locations of predetermined anomalies for modeling study,true anomaly location is right in the area with high consistency between inversion and impedance,while there are many small trap-shape fake structures shown in 1Dinversion and belt-shape fake structures shown in 2Dinversion(better than 1D).Such correction of measured data reveals three high-phase traps(meaning decreasing of resistivity).We chose a low resistivity trap following the coherency principle and interpret it as a most likely kimberlitic pipe,which has been proved by drilling data.The impedance phase invariant correction technique proposed in this work is easy to perform and can recover the response of deep anomalies under complex topography and geology conditions.This technique can be an important supplementary interpretation method or verification tool.
