title = "Sequence, parasequence, and intraparasequence architecture of the Grassy Member, Blackhawk Formation, Book Cliffs, Utah, USA",
abstract = "The upper Campanian Grassy Member of the Blackhawk Formation, Mesa Verde Group, Utah, consists of two high-frequency, unconformity-bounded sequences within the upper part of the Blackhawk Formation highstand sequence set. Within the Grassy Member, the degree of shelf erosion in outcrop appears far less significant than that associated with type 1 sequence boundaries described from the stratigraphically higher Desert Member and Castlegate Formation. There appears to be a hierarchy of unconformities bounding sequences within the Blackhawk Formation recording progressively larger basinward shifts of facies tracts and greater amounts of shelf incision with time. It is suggested that the shoreface evolved from a prograding strand plain into a barrier island prior to formation of the parasequence flooding surface. -from Authors",
