“…All of these cases have the same oscillatory features within a single geochemical formation as in DT. Many similar examples have been described for most CFBs: CAMP (e.g., Marzoli et al., 2019, and references therein; Tegner et al., 2019) , Karoo‐Ferrar CFB (Elliot et al., 1995; Fleming, 1995; Fleming et al., 1992; Luttinen & Furnes, 2000; J. S. Marsh et al., 1997), Siberian Traps (Fedorenko et al., 1996; Krivolutskaya & Sobolev, 2016; Krivolutskaya et al., 2018a, 2018b; Lightfoot, Naldrett, et al., 1990; Reichow et al., 2005), North Atlantic Igneous Province (NAIP, Andreasen et al., 2004; L.

The CAMP section shown in Figure 8a is particularly illustrative since the stratigraphic section is divided into four individual pulses based on paleo‐secular variation analysis each of which has been interpreted to have been erupted within a few hundred years (Font et al., 2011; Knight et al., 2004; Marzoli et al., 2019, although see the discussion in Section 3.3).…”

“…In the southern Brazilian Platform, the voluminous tholeiitic magmatism that preceded the opening of the South Atlantic Ocean culminated in an extensive continental flood basalt (CFB) event, the PIP, with Early Cretaceous ages (Marques and Ernesto 2004). The PIP is the sixth-largest Meso-Cenozoic large igneous province on Earth (Machado et al 2018) and mostly consists of tholeiitic basalts (90%) with minor andesites (7%) and rhyodacites/rhyolites (ca. 3%) (Bellieni et al 1986), totalizing an estimated volume of at least 600,000 km³ of volcanic rocks (Frank et al 2009).…”

Facies architecture and volcanological aspects of silicic rocks from the Palmas plateau, Brazil

The nature of the extensive silicic units of the Paraná Igneous Province is still heavily debated. The silicic rocks that outcrop in the Palmas plateau (Southwestern Parana State) show aphyric texture and TiO 2 < 0.86%, being classified as Palmas-type rhyolites. Physical volcanology criteria are used here to constrain their origin. Textural and structural variations are observed in these rocks, resulting in the description of nine lithofacies: pitchstone; banded vitreous rhyolite; aphanitic rhyolite; rhyolite with planar disjunctions; massive rhyolite; compositionally banded rhyolite; amygdaloid rhyolite, rhyolite with quartz levels, and altered rhyolite. Folded compositional banding associated with volcanic conduits, well-defined lobes and basal autobreccias attest to an effusive origin for most lithofacies. They occur as domes or extensive tabular bodies, fed by volcanic conduits. For both domes and tabular units, the faciological sequence involves (from bottom to top): altered rhyolite; aphanitic rhyolite or rhyolite with tightly-spaced planar disjunctions; monotonous rhyolite with decimetric-spaced planar disjunctions; and top portions with fast cooling features. Only banded vitreous rhyolite differs due to the presence of shards and gas-escape pipes, aspects that imply in a pyroclastic nature. Therefore, a secondary pyroclastic flow created by lava collapse is suggested as its origin, although further studies are required.

“…The basin contains extensive basaltic lava flows, known as the Serra Geral Formation or the Paraná Continental Flood Basalt, which resulted from fissure volcanism associated with the rifting and opening of the South Atlantic Ocean. These basalt flows can reach thicknesses of up to 2,000 meters (Fernandes et al, 2018;Machado et al, 2018). The Paraná basin is of great economic importance as it contains significant reserves of coal, oil, and natural gas.…”

“…The Serra Geral Formation dates from approximately 135 million years ago, and consists of tholeiitic basalts with distinct geochemical characteristics. The province southern part exhibits low-TiO2 and low incompatible element levels, while the northern portion has high TiO2 concentrations (Pacheco et al, 2018;Machado et al, 2018;Rocha-Júnior et al, 2020a).…”
