Comment on “Depth Estimation of Simple Causative Sources from Gravity Gradient Tensor Invariants and Vertical Component” by B. Oruç in Pure Appl. Geophys. 167 (2010), 1259–1272

ORUC (2010) proposes a new method for interpretation of gravity gradient tensor (GGT) data. This method seems interesting in theoretical point of view, although, we have found some flaws in the equations he has derived. In this paper, we correct the introduced equations and describe some theoretical points, briefly.
