RT Journal Article T1 Las tonalitas biotíticas de Aldeaencabo de Escalona (Toledo), Sistema Central Español T1 The biotite-bearing tonalités of Aldeaencabo de Escalona (Toledo), Spanish Central System A1 Villaseca, Carlos A1 Ubanell, A. G. A1 Gómez Mayor, J. AB A new tonalité massif In the centro-iberian region is described. They are scarce and early intrusions outcrop p ing as sm all massifs (< 7 k m 2) in the widespread hercynian granitic magmatism. Aldeaencabo tonalité is characterised by the lack of metaluminous minerals as amphibole or pyroxenes. Chemically is a peraluminous rock rich in incompatible elements (K, Rb, Zr, REE) in comparison to other nearby tonalités. An intracontinental calkalkaline affinity is defined. Nevertheless, the low Ca, Na and Sr contents point to a supressed mantle contibution in the genesis of this rock PB Sociedad Geológica de España YR 1996 FD 1996 LK http://hdl.handle.net/10272/12357 UL http://hdl.handle.net/10272/12357 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 31 may 2026
