Gravity gradient tensor can more intuitively reflect the boundary of underground density anomaly body than gravity anomalies. Gravity inversion based on gradient tensor data can improve the accuracy of simulation of geological body. The cubic spline interpolation method is used to fit gravity anomalies on the basis of spline theory. And then the data of gravity gradient tensor from gravity anomalies is obtained by the spline function which realized by integral derivative relation. And on this basis, tensor Euler inversion is calculated. The tensor Euler decconvolution results of gravity data in Meishan iron mine are more convergent than conventional decconvolution. The horizontal projection range and central burial depth of Meishan main ore body are been accurately described. And there are concentrated Euler solutions in the vicinity of Liujiacun, southern Meishan and Huanglinku-Wujiawa area, which can provide reference for the follow-up prospecting work in Meishan area.
