Ediacaran 2,500-km-long synchronous deep continental subduction in the West Gondwana Orogen
Abstract The deeply eroded West Gondwana Orogen is a major continental collision zone
that exposes numerous occurrences of deeply subducted rocks, such as eclogites. The …

New evidence of an Ediacaran age for the Bambuí Group in southern São Francisco craton (eastern Brazil) from zircon U–Pb data and isotope chemostratigraphy
Extensive carbonate–siliciclastic successions of the Bambuí Group, which overlie

Goldilocks at the dawn of complex life: mountains might have damaged Ediacaran–Cambrian ecosystems and prompted an early Cambrian greenhouse world
We combine U–Pb in-situ carbonate dating, elemental and isotope constraints to calibrate
the synergy of integrated mountain-basin evolution in western Gondwana. We show that …
