“…This package mostly records proglacial-marine deposition including ice-rafted debris (IRD); varve-like, finegrained rhythmites; massive and varve-like black shales; thin-bedded and sandy turbidites; subaqueous outwash fan facies; and chaotic deposits derived from debris-and massflows. According to Aquino et al (2016), the Itararé Group in this area can be subdivided into three depositional sequences, each one composed of glacially influenced, marine to delta deposits, and is unconformably overlain by the post-glacial Rio Bonito Formation. Each depositional sequence represents a glacial subcycle (S1, S2, and S3) recorded by deglacial facies deposited during ice retreat (Deglacial Systems Tract or DST) above a sequence boundary (SB).…”

“…Each depositional sequence represents a glacial subcycle (S1, S2, and S3) recorded by deglacial facies deposited during ice retreat (Deglacial Systems Tract or DST) above a sequence boundary (SB). These basal surfaces are characterized by deformational or scour features related to glacial advance (Aquino et al, 2016) and/or abrupt shift of facies caused by a relative sea level drop associated with a less expressive glacial advance (d 'Ávila, 2009;Fallgatter, 2015).…”

“…van der Wateren 1994, Roberts & Hart 2005), including folds, faults, boudins and foliation. These structures can also be used to give ice-flow kinematics and are documented in the late Paleozoic succession in Paraná Basin (Vesely et al 2015, Aquino et al 2016, however they are not discussed in the present paper. In glacial marine or lacustrine environments blocks of floating ice (icebergs or sea/lake ice) may scour the bottom sediments producing ice-keel scour marks that are shallow to deep scours containing parallel sets of grooves and ridges (e.g.…”
