El primer moviment de població testimoniat al massís de Garraf. Abandonament de la cova de Can Sadurní (Begues) i establiment de la seva comunitat a l’entorn de les mines de Can Tintorer a inicis del neolític mitjà recent. Una hipòtesi de treball cada cop més fefaent.

The excavation and study of the archaeological materials recovered in the 8 postcardial Neolithic layers of cova de Can Sadurní give proof of the mining activity that the group was carrying out since the beginning of the Middle Neolithic (what we call Middle Neolithic I and until recently was considered as belonging to the late early Neolithic). This mining activity, initially focused on the exploitation of quartz in the outcrops found in the Garraf Massif, particularly in the area known as Garraf negre (“black Garraf”), ended up with the discovery of variscite and other green-coloured minerals present in the same geological context. These groups started exploiting the green stone along with quartz. The first distribution networks were developed. Prestige goods arrived to Can Sadurní thanks to the exchange networks connected to the green stones (also called callaite). There was a population increase. Suddenly, around the change of millennium, the presence of the community in the cave stopped. From this moment onwards, the mining community of Can Tintorer, now in the Middle Neolithic II phase or Sepulcres de Fossa culture, appears and grows, which makes us think of a population migration from Can Sadurní Cave to Can TIntorer, which are ca. 8 km apart, within the same territory. This is one of the working hypotheses with which the CIPAG is working within the running research project (2014-2017) “Les comunitats prehistòriques del massís de Garraf nord. Orígens, genètica, patrons d’assentament, trets culturals, recursos i mobilitat durant la prehistòria recent” [The prehistoric communities of the Northern Garraf Massif. Origins, genetics, settlement patterns, cultural traits, resources and mobility during recent prehistory].
