通过比较各段中每个准层序的进积规模和各准层序海相上倾终端的位置,在犹他州上白垩统布莱克霍克组的段内建立了两种独特的重复出现的堆叠地层模式。在同一段内,不论层序界面是否分隔开准层序,最早的准层序总是比较晚的准层序进积较远。其结果是在各段中,进积距离的样式导致了从先进积到后加积的地层堆叠模式。在布莱克霍克组各段,只要其露头适宜追溯非海相—海相的相变位置以判定进积距离,就能观察到上述模式。这些地层模式被用来解释白垩纪前陆盆地海平面随时间相对变化的进程,并可以提供冲断岩片变位特征的信息。作为准层序界限的洪泛事件可代表强化道冲作用期,而最大洪泛面(段的界面)则代表最大冲断岩片运动期。
By comparing the flotation size of each quasi-sequence in each segment with the location of the quasi-sequence marine upturn terminal, two unique and recurring stacks were established within the segment of the Blake Hoker Formation in Upper Cretaceous Utah Stratigraphic pattern. Within the same paragraph, the earliest quasi-sequence always farther than the quasi-sequence later, regardless of whether the sequence boundaries separate the quasi-sequences. As a result, the pattern of progressive distance in each segment resulted in a stratigraphic stacking pattern from advanced to post-accumulation. In the various sections of the Black Hawk Formation, this pattern can be observed as long as its outcrops are suitable for tracing the non-marine-facies phase transition to determine the precession distance. These stratigraphic models are used to explain the relative evolution of sea level over the Cretaceous foreland basin over time and provide information on the characteristics of thrust fragments. The flood event, which is a quasi-sequence boundary, can represent the period of enhanced channeling, while the maximum flood surface (segment interface) represents the period of maximum thrusting.
