Structural evolution of the Benicàssim area (Maestrat basin, NE Spain): insights from fracture and vein analysis
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 fr...

| Sumario: | 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 |
