In recent years, several models have been proposed to explain how ridges have formed on Europa. Each of these models has succsesses and difficulties. Maybe the most direct way to support one of them is thinking on how each mechanism would affect preexisting structures. In particular, crosses between ridges are going to be affected depending on the formation mechanism considered: if we accept either the volcanic or the tidal squeezing models, a preexisting ridge would be rburied?? by the new material; on the other hand, if we accept either the diapiric or the compresional models, a preexisting ridge would be being deformed on the new ridge outer slope. In this work, we use 28 topographic profiles taken from photoclinometric data from E4 orbit. Each of these profiles was choosen in such a way that it passes trhough a crossing between two ridges. Each of these profiles was superimposed to the image from which it was taken by means of SURFER software in order to match a structure with its topographical behavior. The objective was to know if the preexisting ridge involved in a crossing was buried or deformed during the formation of the most recent ridge in that crossing. From 23 crossings that we analised, we found evidences of deformation in 36% of them and posible deformation in another 18%. In the remaining 46% we either did not observe deformation or our method did not permit confident results. The fact that more than 50% of the crossings have shown signs that the more recent band deformed the preexisting band suggests that the formation mechanism of ridges is a mechanism that deforms the surface, maybe the diapiric model or any other similar model worked in order to form ridges.
