“…The whole dataset of Famatinian-aged igneous rocks resembles a concave upwards hyperbola with contrasting endmembers, suggesting that mixing, hybridization and/or contamination processes involving mantle-and crustal-derived materials have taken place. Such processes have been proposed by several authors for the Famatinian orogen (Casquet et al 2012;Cristofolini et al 2012;Walker et al 2015;Otamendi et al 2017;Suzaño et al 2017;Rapela et al 2018;Weinberg et al 2018;Morosini et al 2019;Camiletti et al 2020).…”

“…Felsic to intermediate melt compositions recorded by zircon Th/U ratios were compared with a synthesis of new detrital zircon Hf isotopic results (Table S7), previously published detrital zircon Hf results (Fig. 6C; Willner et al, 2008;Pepper et al, 2016;Otamendi et al, 2017), and zircon Hf isotopic results from bedrock samples (Fig. 6C; Table S9; Dahlquist et al, 2013Dahlquist et al, , 2016Dahlquist et al, , 2018Hervé et al, 2014;Jones et al, 2015;Otamendi et al, 2017;Rapela et al, 2018).…”

“…6C; Willner et al, 2008;Pepper et al, 2016;Otamendi et al, 2017), and zircon Hf isotopic results from bedrock samples (Fig. 6C; Table S9; Dahlquist et al, 2013Dahlquist et al, , 2016Dahlquist et al, , 2018Hervé et al, 2014;Jones et al, 2015;Otamendi et al, 2017;Rapela et al, 2018). The zircon U-Th-Pb and Hf isotopic data sets were integrated with an extensive compilation of bedrock geochronologic data to define temporal, spatial, and compositional variation in Phanerozoic magmatism along the western margin of South America.…”

“…Estos segmentos se encuentran dispersados a lo largo de la paleomargen y han sido denominados en estudios anteriores como el Terreno Chibcha (Restrepo y Toussaint, 1989;Restrepo et al, 2009) y recientemente como el Orógeno Putumayo (Ibáñez-Mejía et al, 2011 Al oriente del Orógeno Putumayo, en el Macizo de Santander y los Andes de Mérida, se presenta un bloque dispersado del Orógeno Caperoniense o Famatiniano de edad Paleozoico Inferior (Ordovícico) (Restrepo, 1995;Mantilla-Figueroa et al, 2016) (Figura 1); que se extiende como fragmentos desde Chile hasta Venezuela, en la protomargen occidental de Gondwana (Ramos, 2008;Otamendi et al, 2017). Este orógeno está representado en Colombia, en los macizos de Santander y Quetame, por unidades sedimentarias, metasedimentarias de muy bajo grado, esquistos, neises migmatíticos, paraneises y granitoides de arco sin-tectónicos y pos-tectónicos (Van der Lelij et al, 2016;Mantilla-Figueroa et al, 2016;Tazzo-Rangel et al, 2019), presentando algunas unidades metamorfismo de la facies anfibolita alta y granulita en la cúspide de la orogenia famatiniana (∼470 Ma) (Zuluaga et al, 2017;Tazzo-Rangel et al, 2019).…”
