Foraminifera are commonly applied as essential tools for relative time control and
reconstructions of paleo/environmental conditions. These single-celled organisms leave in …

The Pennsylvanian on the western rim of Gondwana can be considered a time of significant
contrasts in terms of environments, revealing a unique translatitudinal disposition of the …

Abstract During the Late Palaeozoic, the Gondwana supercontinent formed an extensive
Southern Hemisphere landmass that was affected by multiple glacial episodes, known …

The accuracy of the radiometric ages for the Pennsylvanian-Permian section of the Paraná
Basin has been progressively increased in the past two decades, allowing a better …

The palynostratigraphy of the lower and Coal members of the Copacabana Formation from
Apillapampa, central Bolivia was investigated. Twelve samples yielded abundant and …

Palaeo-loess and silty aeolian-marine strata are well recognized across the Carboniferous–
Permian of equatorial Pangaea. Aeolian-transported dust and loess appear in the Late …

In Bolivia, a marked climatic paleogradient (from west northwest to south) is visible in the
Carboniferous depositional systems. In the northwest is the Pangean trend, a warm-water …

This paper presents new data about Early Permian (Cisuralian) strata, palynostratigraphy
and absolute dating from the Copacabana Formation in central Bolivia. Recent stratigraphic …

Abstract Largely terrestrial Pennsylvanian strata (Macharetí and Mandiyutí groups) in Bolivia
and northern Argentina contain a brief marine incursion. Dominated by glacio-fluvial and …

This work presents a new age framework for the main Bashkirian glacio-eustatic
transgression in Argentina, including the first absolute age for the Jejenes Formation, San …
