“…Thus, remelting of the newly-formed mafic rocks in the mid-tolower crust produced unradiogenic Nd isotopic compositions. Similar negative ε Nd (t) values from felsic igneous rocks are also prevalent in other SIPs, such as the Chon Aike SLIP (Riley et al, 2001) and the Mesoproterozoic Gawler SLIP, southern Australia (Wade et al, 2012), where mafic rocks were also mostly sourced from enriched lithospheric mantle.…”

“…El primer modelo prevé que las riolitas se formen esencialmente por fusión parcial de la corteza (e. g., Huppert y Sparks, 1988) en consecuencia del arribo de grandes cantidades de magmas basálticos desde el manto, que proveerían el calor necesario para fundir la corteza (Ruiz et al, 1988a(Ruiz et al, , 1990Albrecht y Goldstein, 2000;Ferrari et al, 2002). Este modelo ha sido invocado para la generación de otras grandes provincias ígneas silícicas (Graham et al, 1995;Pankhurst y Rapela, 1995;Ewart et al, 1998;Riley et al, 2001;Bryan et al, 2002). En el segundo modelo, las riolitas serían el producto fi nal de la diferenciación de magmas basálticos con poca o nula intervención de la corteza (Cameron y Hanson, 1982;Cameron y Cameron, 1985;Cameron et al, 1980aCameron et al, , 1980bCameron y Robinson, 1990;Wark, 1991;Smith et al, 1996).…”

“…Volcanism continued with the Early to Late Jurassic Chon Aike Province, that covers a wide area of Patagonia, from approximately 40ºS to 55ºS, and constitutes one of the world's most voluminous volcanic silicic provinces (Kay et al, 1989;Pankhurst et al 1998Pankhurst et al , 2000Riley and Leat, 1999;Riley et al, 2001). Volcanism spanned more than 30 Ma, but based on SHRIMP U-Pb zircon, Rb-Sr whole-rock and 40 Ar/ 39 Ar data, three episodes of peak activity have been recognized (Feraud et al, 1999;Pankhurst et al, 2000): a Toarcian-Aalenian episode, between 188-178 Ma, a Bajocian-Bathonian episode, between 172 and 162 Ma and an Oxfordian-Kimmeridgian episode, between 157 and 153 Ma.…”
