Abstract
The Palaeozoic rocks outcropping around Valls are divided into two strati g raphic units. The boundary between both is an unconformity. The lower unit is composed by nearshore platform sediments and a Lower Cambrian age is ind icated according to ichnotaxa content. The upper unit consists of pink nodu lar limestones and dark limestones, and it is followed by siliciclastic Cul m Facies rocks. These limestones contain conodonts of the Uppermost Tournai sian at its base (anchoralis-latus Zone) and Lower Bashkirian (Namurian B) in the upper part. This condensed carbonate sequence was coeval with the th ick siliciclastic Culm sedimentation in the surrounding areas.
