Palynological age constraint of Les Vilelles unit, Catalan Coastal Chain, Spain

Autor: F. GONZÁLEZ, C. MORENO, J.C. MELGAREJO, R. SÁEZ

Publikováno v: Geologica Acta, Vol 13, Iss 4 (2015)

Les Vilelles unit is a detrital sequence exposed at the southwestern margin of the Catalan Coastal Chain (CCC), NE Spain, below the Carboniferous turbiditic series. Based on the palynological content, the age of this unit was initially assigned to th
