The palynology of some Palaeogene deposits between the Rio Esera and the Rio Segre, southern Pyrenees, Spain
Leidse Geologische Mededelingen , Volume 49 - Issue 1 p. 145- 163
In this article the results of a palynological investigation of Palaeogene sediments in the Spanish Pyrenees are discussed. A statistical analysis is used to interpret the counts in the absence of extensive biological and stratigraphical information about the species studied. A broad picture of the climatic changes could be reconstructed together with the different vegetational zones in the coastal swamp area. The presence of Nypa and Nothofagus, probably allochthonous, is at least striking. The biozonation is fitted into a stratigraphic framework based on Foraminifera. A new genus and some new species are described and discussed under Systematics together with all species mentioned in this investigation. A Fortran IV computer programme for the statistical analysis of the data has been added to stimulate other comparative studies.
