1. A method for building a depositional space corresponding to a geological domain of a stratified terrain that comprises horizons, the method comprising: partitioning said geological domain with at least one conformal mesh comprising element coordinates, said at least one conformal mesh matching boundaries of said geological domain, wherein the boundaries comprise the horizons, calculating depositional coordinates defining a depositional space to represent the horizons as substantially planar and parallel, wherein said depositional coordinates calculation comprises computer calculations of fields of displacement along the element coordinates with specified boundary conditions for the horizons using a solid material deformation model for simulating mechanical deformations in the geological domain, wherein said depositional coordinates calculation provides for attribution of point coordinates in the geological domain to point coordinates in the depositional space, allowing points to be mapped therebetween, and wherein said depositional space provides for computing physical properties of the stratified terrain based on measured data for the stratified terrain.
