Abstract Dispersion and deformation of cratonic fragments within orogens require weakening the craton margins in a process decratonization. The orogenic Borborema Province, NE Brazil, is one several Brasiliano/Pan-African late Neoproterozoic that led to amalgamation Gondwana. A common feature these period extension opening narrow oceans preceded inversion collision. For case São Francisco Crato...

The Tonian supercontinent Rodinia is hypothesized to have included almost all Proterozoic continental blocks. Competing models variably place South China at the core or periphery of separated from it entirely. paleogeographic also vary in whether they incorporate large and rapid oscillatory true polar wander associated with ca. 810–795 Ma Bitter Springs Stage. Here, we present paleomagnetic dat...

The tropical Andes are a hotspot of biodiversity, but detailed altitudinal and latitudinal distribution patterns of species are poorly understood. We compare the distribution and diversity patterns of four Andean plant groups on the basis of georeferenced specimen data: the genus Nasa (Loasaceae), the two South American sections of Ribes (sect. Parilla and sect. Andina, Grossulariaceae), and th...
