1. A computer-implemented method of creating subsurface models, comprising: (i) selecting a region of the world to be modeled; (ii) providing geophysical and geographical data corresponding to said selected region of the world; (iii) providing an archive of known geological structures; (iv) providing an interface which permits a user to create a subsurface model of the identified region by: (a) selectively viewing a portion of the geographical and/or geophysical data; (b) selecting a structure from the archive; (c) transforming the selected structure in accordance with the geographical or geophysical data; and, (d) repeating steps (a), (b), and/or (c) to create the subsurface model.
