Abstract The Devonian/Carboniferous Boundary (DCB) interval is associated with mass extinction, isotope excursions and a short glacial episode. This study investigates how boundary extinction environmental change expressed in the high-palaeolatitudinal record of Bolivian Altiplano (western Gondwana). A latest Devonian early Carboniferous section has been investigated using sedimentology, palyno...

En este trabajo se sintetiza el registro estratigráfico de los conuláridos (Familia Conulariidae Walcott, 1886, Orden Conulariida Miller & Gurley, 1896, Phylum Cnidaria Hatschek, 1888) Gondwana para mostrar la importancia estratigráfica estos organismos fósiles. Se ha elaborado una base datos documental que permite identificar períodos y épocas en diversifican más son abundantes.

Commonly, intra-continental wrenching is associated with a high degree of crustal faulting and fragmentation. The resulting continental blocks can undergo vertical-axis rotations, which in turn lead to the generation intricate fault networks within along their boundary regions. Investigations into these structural complexities support understanding when how rotate, what position was prior trans...

The Silurian–Devonian plant radiation was an event triggered by the progressive colonization of subaerial habitats. Nevertheless, it is still unclear whether this globally uniform or alternative diversification scenarios emerged depending on geographical context. Here, we report early land diversity patterns across different previously defined palaeogeographical units (i.e., Laurussia, Siberia,...

Abstract The Triassic tectonic setting of the Tethyan Himalaya in southern Tibet remains controversial and is key to revealing mechanism Neo-Tethys Ocean opening breakup history Gondwana. This paper reports 227–225 Ma mafic volcanic rocks interbedded within sequence Tibet, which were formed a typical passive continental margin setting. basalts are tholeiitic with high TiO2 (3.20–3.38 wt%) moder...

Abstract The Mesoproterozoic MARA terrane of western South America is a composite igneous-metamorphic complex that important for Paleozoic paleogeographic reconstructions and the relative positions Laurentia Gondwana. magmatic detrital records are consistent with Laurentian origin; however, metamorphic deformation lack sufficient detail to constrain correlation units within timing mechanisms ac...
