“…In an intraplate environment in southern Brazil with the crystalline shield sand rocks of the Paraná Basin, research has led to the determination of Paleogene, Neogene, and Quaternary elements and stress fields that modify the current relief. A number of authors have addressed the problem in south and southeastern Brazil (Riccomini et al 1989, Flores et al 1991, Frasca and Lisboa 1993, Souza Filho 1995, Schuck et al 2001, Tomazzoli and Pellerin 2001, Tomazzoli 2002, Salamuni et al 2004, Fortes et al 2005, Grohmann et al 2007, Andrades Filho and Guasselli 2008, Chavez-Kus and Salamuni 2008, Franco et al 2008, Roldan et al 2010, Kröhling et al 2011, Reis and Tomazzoli 2011, Santos et al 2011, Morales et al 2012, Nascimento et al 2013, Souza Junior et al 2013, Oliveira et al 2016. The difficulties in carrying out such studies in mountainous areas with thin regolith and little Cenozoic sedimentary cover have been circumvented by recognizing reactivated Precambrian and Paleozoic structures, tectonic relief and drainage control, and distinguishing of Neogene to Quaternary events.…”
