The Ediacaran sedimentary architecture and carbonate productivity in the Atar cliffs, Adrar, Mauritania: Palaeoenvironments, chemostratigraphy and diagenesis

The palaeogeographic development of a palaeorelief associated with the end of glacial conditions and deposition of the onlapping Atar cap carbonate is related to the presence of interbedded felsic bentonites and phenocrysts, and reflects the intermittent influence of a neighbouring explosive volcanism.
