The genomic history of the Iberian Peninsula over the past 8000 years
2019
We assembled genome-wide data from 271 ancient Iberians, of whom 176 are from the largely unsampled period after 2000 BCE, thereby providing a high-resolution time transect of the Iberian Peninsula. We document high genetic substructure between northwestern and southeastern hunter-gatherers before the spread of farming. We reveal sporadic contacts between Iberia and North Africa by ~2500 BCE and, by ~2000 BCE, the replacement of 40% of Iberia's ancestry and nearly 100% of its Y-chromosomes by people with Steppe ancestry. We show that, in the Iron Age, Steppe ancestry had spread not only into Indo-European-speaking regions but also into non-Indo-European-speaking ones, and we reveal that pre…
Polythiophenes as markers of asphalt and archaeological tar pitch aging. Characterization using solid-state electrochemistry
2018
The voltammetry of immobilized microparticles (VIMP) was used to characterize organosulfur components from ovens found at the Spanish archaeological sites of Cueva de Nerja (ca. 35,000cal BC), la Illeta dels Banyets (4th century BCE) and Gestalgar (12th–13th CE), and asphalt probes subjected to PAV and SUNTEST aging protocols. The voltammetric responses of the archaeological samples and the asphalt probes after photodegradation were quite similar, indicating the presence of polythiophene components which could act as age/degradation markers.

A testimony of pitch production in the Protohistory of the Iberian Peninsula: The kiln of La Illeta dels Banyets (El Campello, Alicante)
2022
Durante la campaña de 2009-2010 en el yacimiento arqueológico de la Illeta dels Banyets se localizó un basamento circular, una pileta y un depósito excavado en el subsuelo que formaban parte de un único equipamiento dedicado a una actividad productiva. Por sus características y por los análisis antracológico y químico se ha identificado como un horno para la destilación de pez o brea, cuyo proceso de fabricación se ha visto confirmado con paralelos arqueológicos y etnográficos. Datado entre finales del siglo IV y la primera mitad del siglo III a.C., es la primera instalación completa de este tipo conocida para el periodo protohistórico en la península ibérica. During the 2009-2010 campaign …
