Stratigraphy
| Formation: | Tahkandit | ||||
| Stratigraphy comments: The time interval given by the authors is Leonardian and ? Guadalupian. The Permo-Pennsylvanian in the northern Yukon is ideally divided into three units called, in ascending order: Lower Limestone unit, Middle Recessive unit, and Tahkandit Formation (Nelson, 1961a, b, 1962b). |
