Abstract：The western margin area of Ordos Basin is characteristic of not only larger fluctuant surface and complex underground structure,but also large variation of loess thickness,leading to poor effect of seismic exploration.The key of effects in gravity and CEMP exploration is whether the influence of the fluctuation of giant-thickness of loess layer and topographic fluctuation on gravity anomaly can be eliminated or not,and reduces or suppresses the influence of topography and random noise on static displacement of CEMP data.For that reason,the paper presented a set of method of correction of gravity anomaly in the loess-covered area and method for suppressing CEMP static displacement in loess plateau area.The good exploration effects were achieved by integrated processing,interpretation and study of CEMP and high-precision gravity data,playing the better role in optimization of target benefit for exploration.
