Resumen:
We present the first palynological study of the La Deheza Formation in Paganzo Basin, San Juan Province, Argentina. A total of eighteen samples were studied and one hundred and sixteen palynomorph species were recorded. A multivariate statistical (R) analysis confirmed the occurrence of three associations. Assemblages 1 (240 m), 2 (230 m) and 3 (220 m) were referred to biozones already registred in the Paganzo Basin, i.e. Raistrickia densa-Convolutispora muriornata (DM), Pakhapites fusus-Vittatina subsaccata (FS) and Lueckisporites-Weylandites (LW) biozones. These Assemblages can be assigned a Pennsylvanian?Cisularian age based on previous stratigraphic records of the identified species.
