Geological constraints on Neoproterozoic glacial episodes
… episodes for correlation, yet Neoproterozoic tillites remain stratigraphically under-constrained. This thesis investigates stratigraphic and sedimentological constraints on Neoproterozoic glacial episodes through field based case studies on all Neoproterozoic purported tillites in Britain and …
