RT Journal Article T1 Metamorfismo y magmatismo del Paleozoico inferior en la zona central de las Sierras Pampeanas (SW de Gondwana) T1 Lower Paleozoic metamorphism and plutonism in the Central Pampean Ranges (S. W. Gondwana) A1 Pascua, M. I. A1 Saavedra, J. A1 Baldo, Edgardo G. AB The Sierra de Los Llanos intrusion is a Lower Paleozoic pluton of meta-aluminous granites (with tholeiitic and calc-alkaline features) representative of batholiths of the Sierras Pampeanas, here associated to small bodies of cordieritic granite and metamorphic septa that upgrade from weak contact to strong grade of metamorphism, emplaced at low depth. The first data (spatial and temporal associations, etc.) suggest a genetic relation to a heterogeneous source, with contamination, by crustal materials and other processes, of mantelic arc magmas PB Sociedad Geológica de España YR 1996 FD 1996 LK http://hdl.handle.net/10272/13306 UL http://hdl.handle.net/10272/13306 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 15 jun 2026
