“…Data from seismic reflection, potential-field, well, geological outcrop and seismicity are used in this paper to improve our knowledge on several recently known geological structures based on seismic reflection data. These are the Porto Alto fault (Carvalho et al, 2006a), the Pinhal Novo fault (Rasmussen et al, 1998;Cabral et al, 2003;Kullberg, 2000) and Azambuja fault (Rasmussen et al, 1998;Cabral et al, 2004). Except for the papers from Carvalho et al (2006a;b), the previous work was based on paper stacked sections.…”
