“…4A) and the Puncoviscana Formation. The detrital zircon age patterns observed here are similar to pre-to syn-Pampean orogeny Gondwanan provenance in the Puncoviscana Formation of eastern Sierras Pampeanas and in NW Argentina (Rapela et al, 2016).…”

“…Several studies have dated detrital zircon in the Cambrian Puncoviscana complex or Puncoviscana Formation (Rapela et al, 2007;Adams et al, 2008Adams et al, , 2010Escayola et al, 2011) and revealed mainly Cambrian depositional ages. Therefore, the Puncoviscana complex is associated with the evolution of the proposed Cambrian Pampean continental arc (Ramos, 2008;Collo et al, 2009;Escayola et al, 2011;Rapela et al, 2016).…”

“…Exposed schists and gneisses in northwest Argentina are mostly interpreted as basement and the deeper crustal equivalent of the Puncoviscana complex (Willner et al, 1990;Rapela et al, 1999;Büttner et al, 2005;Rapela et al, 2007;Miller et al, 2010), but these rocks have seldom been the focus of provenance studies (Rapela et al, 2007(Rapela et al, , 2016Verdecchia et al, 2011). Some rocks in northwest Argentina, and the Arequipa-Pampia-West Pampeanas block (MARA), have thus far been assigned a Mesoproterozoic age (Lucassen et al, 2000;Casquet et al, 2008;Ramos, 2008;Rapela et al, 2010)-but the region is still devoid of proven Neoproterozoic metasedimentary rocks, pre-dating the Puncoviscana complex.…”

“…Except for the role of the Puncoviscana Complex (see compilations in Escayola et al, 2011;Rapela et al, 2016)-which remains controversial-very little is known about Pre-Pampean (>550 Ma) geodynamic evolution in the Central Andes. This study uses geochronologic and geochemical analyses to investigate the significance of quartzites, exposed in southern Puna in northwest Argentina, for the geological evolution of the region-and thereby western Gondwana.…”

This paper summarizes the main sedimentary sequences of major cratonic basins during the breakup of Rodinia and the assembly of Gondwana and extracts evolutionary stages of the Neoproterozoic basins around the Paleo‐Pacific Ocean and Iapetus Ocean tracts. During the breakup of Rodinia, sedimentary sequences and evolutionary stages of the main basins in major cratonic blocks, such as Yangtze, Australia, Eastern American, Western American, and Western Africa cratons, mostly experienced intracratonic rifting, drifting or passive continental margin, carbonate platform construction, and foreland basin stages. The time of rifting to drifting transition in Congo‐São‐Francisco precisely marked the closure of the Adamastor Ocean between Congo‐São‐Francisco and Rio de la Plata and presaged the opening of the Iapetus Ocean. The time of rifting to drifting transition of Eastern American of Laurentia and West Africa initiated at ~580 Ma also signified the opening of the Iapetus Ocean. The time of drifting stage of the main basins around the Paleo‐Pacific Ocean tracts is not only earlier than those of the Iapetus Ocean tracts but also is characterized by diachronism. The time of drifting onset of basins in the Yangtze Block is ~720 Ma, the time of drifting initiation of the Adelaide Fold Belt in South Australia is 680 Ma, and the time of drifting stage of the south‐western margin of Laurentia occurred at 550 Ma. The different times of rifting to drifting transition of the Adelaide Fold Belt in South Australia, the Yangtze Craton, and Western American of Laurentia signified the nonisochronous opening of the Neoproterozoic Paleo‐Pacific Ocean.
