Abstract The Bambui Group is a ca. 2,000 m-thick mixed biochemical-siliciclastic
sedimentary succession that accumulated in the Sao Francisco Basin, central Brazil. Its age …

Neoproterozoic marine systems are associated with major paleoecological changes that
took place in the Ediacaran and during the Ediacaran-Cambrian transition. During this …

In order to investigate the geochemical responses of Earth's oceans and atmosphere after a
Snowball glaciation, we studied an Ediacaran cap carbonate profile pertaining to the base of …

In the terminal Neoproterozoic, drastic climate changes associated with biological
innovations are coupled to isotope and elemental geochemical anomalies. However, lateral …

The Una Group, Irecê Basin (Bahia state) is correlative with the better known Bambuí Group
of the São Francisco Basin (Minas Gerais state); these basins are remnants of widespread …

We present carbon and oxygen isotopic data on carbonates along three profiles of the
Neoproterozoic Bambuı́ group in central Brazil. This unit covers an area of more than 300 …

Abstract The Seridó Belt, at the extreme northeast of Brazil, is one of the several
Neoproterozoic mobile belts related to the Brasiliano/Pan-African Orogeny in Western …

Paleontological and radiometric dating methods (RbSr, KAr and PbPb) suggest
Neoproterozoic ages for sedimentary carbonate rocks of the BambuíGroup in the southern …

The lack of biostratigraphic controls and suitable minerals for radiometric age
measurements made chemostratigraphy a potential alternative for the establishment of a …

Stable isotope ratios combined with elemental compositions and molecular biomass data
provide a powerful tool in Neoproterozoic palaeoenvironmental interpretations. Here, we …
