Statistical analysis of 2D trace-line maps of fracture networks in carbonate rocks of the Jandeíra Formation in Brazil

The first stress field, characterized by a NS-oriented compression, occurred from the Campanian to the Miocene. The second occurred from the Miocene to the Quaternary as an EW-oriented compression. In the western...
