Thompson and Bowring (2000); 6. Myrow and Kaufman (1999); 7. Clauer and Deynoux (1987); 8. Brasier et al. (2000); 9. Norin (1937); 10. Evans et al. (2000); 11. Walter et al. (2000); 12. Grey and Corkeron (1998), Li (2000); 13. Frimmel (in press) [**McMillan (1968) would place Kaigas post-741±6 Ma]; 14. Hoffman et al. (1996); 15. Corsetti and Kaufman (submitted); 16. Narbonne and Aitken (1995). Correlation of glaciations by column is rather arbitrary due to meager radiometric age constraints. Glacials in bold type are discussed in text.
