Stratigraphy comments: said by Hickey et al. 1983 to be Clarkforkian and within Chron 25N, but clearly Wasatchian, and paleomag correlation seriously questioned by Kent et al. 1984 Eureka Sound Group was originally treated as a formation, but broken into multiple formations by Miall (1986); the Margaret Formation is the same as Member IV of West et al. (1981) |
