ABSTRACT

An abnormally thick sequence of carbonate rocks near Connor Lakes in southeastern British Columbia includes ten foraminiferal zones of Middle Tournaisian to Early Namurian age. Representatives of both Eurasiatic and American cratonic faunas are present which permit correlation with the original Carboniferous type sections as well as with standard Mississippian sequences. Lithostratigraphic comparisons with the type sections of the Banff, Livingstone, Mount Head and Etherington Formations are possible, although important facies differences exist. The foraminiferal assemblages within these formations at Coccon Lakes show that:

1. The "Banff-Livingstone" contact is synchronous with the Banff-Livingstone contact in the Highwood Range area.
2. The lower part of the "Livingstone" is condensed.
3. The upper part of the "Livingstone" is probably younger than the Livingstone of the type area and could be equivalent to the Wileman and Baril Members of the type Mount Head Formation.
4. The "Mount Head" of the Connor Lakes section is equivalent to the Salter through Carnarvon Members of the type area.
5. The "Etherington" is equivalent to the lower and part of the middle units of the Etherington Formation at its type section.
