“…In the geological records, slumps commonly occurred in two locations, high up in the slope and lower down of the slope profile due to the susceptibility of slope facies to downslope creep [41]. The origin and use of the slump structures as indicators of paleoslope have been documented in many works [42][43][44][45][46][47][48]; thus, there is a consensus on their use for inferring the paleobathymetry and possible triggering means of the movement of the sediment on the paleoslope. The triggering mechanism could be failure of slope, which is driven by gravity or involvement of seismicity [44,49].…”

“…Large negative C-isotope excursions in the Neoproterozoic times are generally associated to the postglacial carbonate succession and probably reflect oceanographic processes (Kaufman et al 1991, Kaufman et al 1997, Hoffman et al 1998. In Brazil, several studies conducted in the southwestern Amazonian Craton recognized diamictite underlying post-glacial carbonate Neoproterozoic successions (Nogueira & Riccomini 2006, Alvarenga et al 2008, Soares & Nogueira 2008, Soares et al 2013.…”

“…Ocorrem camadas brechadas, falhas sin-deposicionais, estruturas de escorregamento (slumping) e diques netunianos, indicando uma instabilidade gravitacional e choques sísmicos (Nogueira et al, 2003;Soares et al, 2013). É comum ainda a presença de estilólitos, resultando em uma pseudo-estratificação.…”

“…Na análise estrutural rúptil foram empregados dados de falhas estrias e juntas que interessam às seguintes unidades estratigráficas: Formação Puga, Grupo Araras (Alvarenga & Trompette, 1993). (Soares et al, 2013). A ocorrência de estruturas sin-sedimentares é bem documentada ao longo do Segmento Norte da Faixa Paraguai.…”
