  • The Benicàssim area, in the Maestrat Basin, is affected by structures of different scale that are the result of several tectonic events. This contribution presents an outcrop-scale analysis of orientations and relative timing of fractures, striations and veins. The results indicate that there are fractures with the following strikes: N-S, NNE-SSW, E-W y NW-SE. They have striations that record different movement directions: (#1) dip-slip in fault planes oriented N-S and E-W that indicate normal fault movement; (#2) strike-slip in NNESSW to N-S-oriented fractures and conjugate sets of en-echelon calcite veins; (#3) reverse oblique-slip reverso in faults oriented NNE-SSW y N-S; and finally (#4) tilting of layers towards the NE to NW, with layer-parallel slipping.
