Beiras and Extremadura 2022: Petrological Analysis and Restauration
In April 2022, we extended our petrological analysis of stelae in Portugal and in Spain, namely Extremadura. The monuments were analysed both mesoscopically (non-invasive) and, in some cases, through invasive sampling. All stelae that were subject to core-drilling have been restored on the spot. // Em Abril de 2022, estendemos a nossa análise petrológica às estelas em Portugal e em Espanha, nomeadamente na Estremadura. Os monumentos foram analisados por mesoscopia (não invasiva) e, em alguns casos, através de amostras invasivas. Todas as estelas que foram sujeitas a perfurações do núcleo foram restauradas no próprio local.
Beira and Extremadura 2022: Outcrops and Stelae - Afloramientos y Estelas
In our fieldwork campaign during April 2022, we refined our search for outcrops in the Beira and provenanced quartzite stelae in Extremadura. Samples were taken for petrographic as well as geochemical analysis. This time, the stonemason and local researchers accompanied the geologist to most outcrops, to facilitate our research from both perspectives - scientific and practical - on the rocks. // Na nossa campanha de campo durante o mês de Abril 2022, refinamos a nossa procura na Beira por afloramentos e, na Estremadura, pelo local de proveniência da estela quartzítica. Tiraram-se amostras para análises petrográficas e geoquímicas. Desta vez, o artesão e os investigadores locais acompanharam o geólogo à maioria dos afloramentos, por modo a facilitar a investigação das rochas de ambas as perspetivas – tanto de ordem científica como de ordem prática.
Beira Interior 2021: Outcrops and Stelae - Afloramientos y Estelas
In our fieldwork campaign during September 2021, the focus was on the surrounding outcrops of rocks that had been used for the stelae, from where samples were taken for petrographic as well as geochemical analysis. In October, we verified the results together with the stonemason and discovered more possible outcrops.
