Stratigraphy
| Formation: | Haida | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the lower sandstone member of the Haida Fm, which rests with apparent unconformity on the Jurassic Yakoun Fm, and is overlain by the shale member, which passes up into the Honna Fm. AGE: Albian, on the basis of ammonite biostratigraphy. STRATIGRAPHIC POSITION: Presumably near the upper part of the local section. | |||||
