Field Trip 1:  Mining Through the Ages in Portugal; Old and New Practices

Thursday 13 September, 09:00 - 17:30 hrs

Field trip leader: Manuel Matias (University of Aveiro) , Sara Leaf (University of Porto) and Alexandra Lima (University of Porto)

Field Trip Description

The focus of this field trip is on exploring mining through Portugal’s history. You will visit the Valongo Slate Company, which was established in 1865. The Slate company originally supplied England and the US with slate for building, and still produces slate for many European countries.

This quarry is the oldest active quarry in Portugal, with 15 hectares of extracting area, and it lies in a structural formation called ‘anticlinal de Valongo’, providing ideal conditions for extraction. The slate is from the Ordovician period, 450 million years ago.

Then, after a sit-down lunch at a traditional restaurant in the historic village of Quintandona, we will head onto the gold mining museum, ‘Centro de Interpretação das Minas de Ouro de Castromil e Banjas’. 

For both visits you will need a sturdy pair of waterproof boots!
