Approaches on palynology, biostratigraphy and correlation of the Machareti and Mandiyuti Groups, Neopaleozoic of the Tarija basin, Salta province, Argentina
The recognition of 165 indigenous species and their stratigraphic range in the Macharetí and Mandiyutí Groups from Tarija Basin (northern Argentina and southern Bolivia) is used to propose a biostratigraphic scheme composed of a Superzone named Kraeuselisporites volkheimerii-Circumplicatipollis plic...

| description |
The recognition of 165 indigenous species and their stratigraphic range in the Macharetí and Mandiyutí Groups from Tarija Basin (northern Argentina and southern Bolivia) is used to propose a biostratigraphic scheme composed of a Superzone named Kraeuselisporites volkheimerii-Circumplicatipollis plicatus, which is divided into five First Appearance Interval Palynozones. The first three oldest zones, called Crassispora kosankei - Cystoptychus azcuyi, Raistrickia radiosa - Apiculatasporites spinulistratus and Dictyotriletes bireticulatus - Cristatisporites chacoparanensis, are attributed to an early-middle Late Carboniferous age, while the other two, named Granulatisporites micronodosus - Reticulatisporites reticulatus and Marsupipollenites triradiatus - Lundbladispora braziliensis, are referable to the late Late Carboniferous. The age is based on the biostratigraphic range of several key-species and the location of each palynozone within the lithostratigraphic succession. The abundant presence of species in common with other palynofloras from the Late Carboniferous of South America, especially from Argentina and Brazil, also supports this age. Regarding the 154 reworked species recognized, they confirm the deposition of Uppermost Devonian and Lower Carboniferous strata at the Argentinean part of the basin, which would have belonged to the Oriental Protocordilleran and Michicola Arc.
