Different methods can be used for estimating Moho parameters i.e crustal thickness and crust-mantle density contrast e.g. seismic and gravimetric methods. We developed a gravimetric-isostaic model to determine Moho parameters (cf. Sjöberg 2009, Bagherbandi 2011 and Bagherbandi et al. 2013). According to gravimetric-isostatic models, the topographic mass surplus and the ocean mass deficiency are compensated either by a variable crustal thickness or density. Isostatic equilibrium is described by means of the isostatic gravity anomalies which should theoretically be equal zero, provided that the refined Bouguer gravity anomalies are isostatically fully rebalanced by the corresponding gravitational attraction of compensating masses. Moho parameters can be used in different geophysical and geodynamical applications such as sub-crustal stress determination, etc.
