Stratigraphy
| Geological group: | Alma | Formation: | Deborah Volcanic | ||
| Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Deborah Volcanic Fm, which is the middle unit of the Alma Group, overlain by McDonald Limestone, and overling the Totara Limestone. AGE: Whaignaroan in text of Gage (1957); Whaingaroan = Rupelian to earliest Chattian; here assigned to Early Oligocene to avoid orphaning. STRATIGRAPHIC POSITION: Uknown position with unit. | |||||
