[ We claim:] [1.] A method of modeling geological sections of a formation having tectonic deformations, in order to determine a position of hydrocarbon deposits, said method comprising:(a) selecting an undeformed initial geometry of the formation composed of geological objects having determined boundaries;(b) dividing the geological objects into beds;(c) defining separately each bed with a grid including a superposed series of meshes provided with nodes;(d) separately and successively applying tectonic deformations to the series of meshes while preserving a thickness and length thereof, beginning with a first series of meshes having at least one side of the first series belonging to a boundary of the geological objects; and(e) studying transfer of heat and fluids in a sedimentary basin modeled in accordance with a model produced from steps (a)-(d) to determine zones most likely to contain hydrocarbon deposits.
