Depositional Controls over the Lacustrine Source Rocks of the Cuyana Basin. An Approach to Model a Mechanical Cyclicity Through an Integrated Analysis of Sequence Stratigraphy, Petrophysics and Rock Properties

Abstract: Integrating field and laboratory data is possible if there are strong geologic criteria to relate them. This challenge demands understanding rocks from the fabric and mineralogy up to the architectural elements of rock bodies at a basinal scale. The geological properties of rocks, being them clastic, chemical or biochemical, influence reservoir quality and hydrocarbon producibility, but continental mudrocks/siltstones (shales) are by far more complex because of their depositional nature and highly variable ver… Show more

“…Moreover, during the deposition of the Río Mendoza and Cerro de las Cabras Formations, a warm and semi‐arid to sub‐humid palaeoclimate prevailed (Benavente et al., 2015; Mancuso et al., 2021), but with a marked seasonality, in particular for the latter unit (Artabe et al., 2001; Stipanicic & Volkheimer, 2002; Mancuso et al., 2020). Such palaeoclimate conditions were also evidenced through the development of saline–alkaline lakes, even with abundant carbonate deposits which were not documented in the rest of the Triassic units (Zamuner et al., 2001; Barredo & Stinco, 2013; Barredo et al., 2017; Benavente et al., 2019; Salduondo et al., 2020; Mancuso et al., 2021). Carbonate deposits have been interpreted as palustrine systems which were preserved at distal position with respect to sediment input areas (Kokogian et al., 2001; Benavente et al., 2015).…”

“…In this region, Triassic deposits are of continental origin and related to a tectonic extensional phase known as the Huarpic phase (Azcuy & Caminos, 1987), which controlled the development of north-west/south-east rift systems included in the Cuyo, Villa Union-Ischigualasto-Bermejo Basins (Zencich et al, 2008;Barredo, 2012). The Cuyo Basin encompasses part of Mendoza, San Juan and San Luis provinces (Argentina) between 31°and 36°S to 67°and 69°30 0 W reaching more than 60 000 km 2 with different depocentres or Sub Basins of half-graben geometry: Rinc ón Blanco, Santa Clara, Tupungato, Cacheuta, Rivadavia, Ñacu ñán, General Alvear and Beazley, among others (Lopez Gamundı ´et al, 1994;Spalletti, 1999Spalletti, , 2001Stipanicic & Marsicano, 2002;Barredo, 2012;Barredo et al, 2012Barredo et al, , 2017. This work was carried out on outcrops of the Cacheuta -Tupungato Sub Basin (Fig.…”

“…Estos depósitos se interpretan como llanuras tobáceas en donde se desarrollaron espesos paleosuelos tal como lo indica la presencia de halos de raíces, superficies de deslizamiento de las arcillas y pedones (Spalletti, 2001;Tabor et al, 2006;Melchor, 2007). Estos niveles tienen características de Vertisoles-Argilisoles de acuerdo a los criterios de Mack et al (1993), Tabor et al (2006) también descriptos por Barredo (2004Barredo ( y 2017 y Benavente et al (2014). En general, a nivel microfacial se observó también la interacción de los líticos con plantas y otros microorganismos, evidenciado por la presencia de raíces que rompen la estructura sedimentaria (Murcia et al, 2013;Drovandi et al, 2017).…”

“…Durante los periodos intereruptivos fueron colonizados por vegetación, desarrollando suelos incipientes en los depósitos finos del techo de cada paquete. Estos depósitos fueron interpretados previamente porSpalletti (1994) yBarredo et al (2017) como planicies volcaniclásticas, con lo que se concuerda, aunque destacando la ausencia de retrabajo y mezcla de los depósitos con sedimentos epiclásticos. Este miembro estaría marcando el momento de mayor aporte volcaniclástico al sistema, caracterizando un periodo syneruptivo.…”

“…Las Cuencas triásicas argentinas presentan depósitos continentales y se disponen en dirección noroeste-sureste con respecto a la estructuración principal de los Andes (Spalletti, 1999;Spalletti et al, 2005;Barredo y Ramos, 2010;Barredo et al, 2017; entre otros). Estas cuencas se encuentran ubicadas en el oeste del país y son las siguientes: Ischigualasto -Villa Unión (ubicada en las provincias de San Juan y La Rioja), Marayes (ubicada en la provincia de San Juan), Cuyana (ubicada en las provincias de Mendoza, San Juan y San Luis) y depocentro de San Rafael (ubicado en la provincia de Mendoza) (Spalletti, 1999).…”
