The siliciclastic Permian-Triassic deposits in Central andudNortheastern Iberian Peninsula (Iberian, Ebro and CatalanudBasins): A proposal for correlation

摘要

The siliciclastic deposits of the Iberian, Ebro and Catalan Basins have been described for more than a century,udbut facies similarities and a lack of biostratigaphic data have difficulted the correlation of the local stratigraphicudunits in a general framework up to now. Combining pollen and spores data, the identification of the regionaludunconformities and hiatuses and the quantitative analysis of the subsidence by backstripping methods, a newudcorrelation scheme for these facies is proposed.
