DOI: 10.1016/j.lithos.2021.106002
Abstract: Abstract In this paper we report a combined zircon U–Pb–O isotopes and bulk-rock Sr–Nd–O isotopes study on granitic rocks from the Jalama pluton, Central Iberian Zone. Zircon U--Pb ages of representative granitic rock samples are… read more here.

DOI: 10.1017/s0016756821000339
Abstract: In the Central Iberian Zone, the Cadomian orogenic collapse is represented by chaotic megabreccias, olistostromes and mélange deposits reflecting a drastic change from slope-related deposits, fed by denudation of the Cadomian arc, to offshore-dominant settings… read more here.

DOI: 10.1080/00206814.2017.1316687
Abstract: ABSTRACT The Jálama pluton (JP) is a Variscan peraluminous granitoid that intruded into low-grade metasediments from the Central Iberian Zone (CIZ). It comprises a sillimanite-bearing two-mica monzogranite in the inner zone, followed by a tourmaline-bearing… read more here.

DOI: 10.1344/geologicaacta2017.15.4.7
Abstract: The Valdepenas pluton is the easternmost outcrop of the Caceres-Valdepenas magmatic alignment (southern Central Iberian Zone). This massif is constituted by a cordierite-bearing porphyritic monzogranite and may be grouped within the so-called “Serie Mixta” granitoids.… read more here.
