Bedding on both sides of the Mississippian-Jurassic unconformity is so nearly parallel that the angular relationship of the formations involved is difficult to determine by conventional means. Bedding-plane orientation data from four localities where the beds of the Jurassic Fernie Formation are subparallel to those of the Mississippian Mount Head Formation were investigated by the Fisher probability density function test. An analysis of 88 bedding-plane readings shows that the angular discordance ranges from 3.2 to 4.2 degrees.
