The gradual discovery that late Neoproterozoic ice sheets extended to sea level near the
equator poses a palaeoenvironmental conundrum. Was the Earth's orbital obliquity> …

The Neoproterozoic contains severe glacial intervals (750–580 Ma) including two extending
to low palaeomagnetic latitudes. Paucity of radiometric dates indicates the need for …

The Snowball Earth hypothesis explains the development of glaciation at low latitudes in the
Neoproterozoic, as well as the associated iron formations and cap carbonates, in terms of a …

Of the many models that have been proposed to account for the enigmatically widespread
and apparently low-latitude Neoproterozoic glaciogenic deposits, three are widely …

Using a simple 3‐box model of the ocean‐atmosphere system, we simulate the cycling of
carbon and strontium in the aftermath of a global glaciation. Model simulations include the …

Abstract The Neoproterozoic interval (1000–540 Ma) contains ample evidence for a series of
glacial intervals. These include the 750–700 Ma Sturtian glaciation, the 625–580 Ma …

It has recently been found that Neoproterozoic glaciogenic sediments were deposited
mainly at low paleolatitudes, in marked qualitative contrast to their Pleistocene counterparts …

The behavior of the terrestrial glacial regime during the Neoproterozoic glaciations is still a
matter of debate. Some papers claim that the glacial sequences cannot be explained with …

New stratigraphic, geochronological and palaeomagnetic constraints allow updates to be
made to a synthesis of Neoproterozoic glacial palaeolatitudes, including modifications to …
