Supplementary Material

Supplementary material 1. Whole-rock geochemistry data for studied mafic samples from la Codosera syncline-Central Iberian Zone.

Supplementary material 2. Whole-rock geochemistry data for studied mafic samples from Guadalmez and Almadén synclines-Central Iberian Zone.

Supplementary material 3. Operating conditions for the LA-ICP-MS equipment

Supplementary material 4. Total Alkali Silica diagram (TAS) from Le Bas et al. (1986) showing the samples studied in this work and in previous studies done by Higueras (1995); Higueras et al. (2013); López-Moro et al. (2007).

Supplementary material 5. Cathodoluminescence micro-photographs of the studied apatite crystals for samples A) SA2022C; B) SA2026; C) AL2075; D) AL2076. In cathodoluminescence images, the apatite crystals do not show any oscillatory zoning. The lack of any zoning along fractures suggests the lack of hydrothermal dissolution/recrystallization processes and supports their main primary character. The apatites exhibit homogeneous colours ranging from yellow, green, violet and blue

Supplementary material 6. Average electron microprobe analyses and corresponding structural formulas of apatite for the mafic samples dated in this study.

Supplementary material 7. Average electron microprobe analyses of apatite for the dolerites samples dated in this study, compared to the apatites from the Armorican massif dolerites (field in green) by Pochon et al. (2016b). The halogens content plot has been modified from Boudreau (1995).

Supplementary material 8. Representative LA-ICP-MS U-Pb apatite data for studied samples.
