[ES] Se presenta y describe un programa (STRBA) en Basic para la obtención de las gráficas que, siguiendo el método propuesto por RAMSAY (1967), conducen a la estimación del valor de la deformación en el plano por el que se ha seccionado la roca que contiene los objetos deformados. Aplicado a una muestra de «manchas» discoidales metamórficas existentes en un nivel pelítico-samítico entre las capas, principalmente carbonatadas, de Hontanares (estribaciones sur de Gredos) se deduce la existencia de una deformación por aplastamiento subvertical. Las relaciones entre la disposición de estas lentículas y la estratificación sugiere una sincronicidad entre los procesos de plegamiento e intrusión granítica.
[EN] A basic program is presented (STRBA) to plot the graphics of the Ramsay's method for estimating the strain elipse from a «section» of rock with deformed ellipsoidal objects.Has been applicated to 100 discoidal spots (of metamorphic origin) included in pelitic-samitic beds between a marble formation, neighborhood of Hontanares. The result established for this disk-shaped an plane strain in the vertical dirección. The near relation between the folded stratification and the structural characters of the spots, suggest a synchronism in the folding, metamorphism and granitic intrusion, in this point.
