This composition places shale in a category of sedimentary rocks known as " mudstones ." Shale is distinguished from other mudstones because it is fissile and laminated.Nearly 100 m of shale lie below this fossiliferous interval in the Burgess Shale Formation. Assuming 40% post-depositional compaction of strata below the Phyllopod Bed, a conservative estimate for minimum water depth at the time of deposition would be approximately 100 m, essentially the lower limit of the effective photic zone. radar wbal On the shelf, the Heebner is thin (1-3 m) and dominantly black with abundant phosphatic nodules, indicating anoxic conditions.
