A Neoproterozoic snowball earth

PF Hoffman, AJ Kaufman, GP Halverson, DP Schrag - science, 1998 - science.org
Negative carbon isotope anomalies in carbonate rocks bracketing Neoproterozoic glacial
deposits in Namibia, combined with estimates of thermal subsidence history, suggest that …

Did the breakout of Laurentia turn Gondwanaland inside-out?

PF Hoffman - Science, 1991 - science.org
Comparative geology suggests that the continents adjacent to northern, western, southern,
and eastern Laurentia in the Late Proterozoic were Siberia, Australia-Antarctica, southern …

The snowball Earth hypothesis: testing the limits of global change

PF Hoffman, DP Schrag - Terra nova, 2002 - Wiley Online Library
The gradual discovery that late Neoproterozoic ice sheets extended to sea level near the
