Improved age constraints on the Wahweap Formation indicate that the middle and upper members were deposited during the eustatic Claggett transgression (T8 of Kauffman 1977) in the adjacent Western Interior Seaway. Additionally, facies analysis of the Wahweap Formation has revealed an increase in both the sand:mud ratio and the degree of sandstone amalgamation from the upper part of the middle member to the base of the capping sandstone, suggesting a gradual reduction in generation of accommodation in the basin. Following recent alluvial sequence stratigraphic models, the middle member is interpreted as the isolated fluvial facies tract, while the upper member represents the tidally influenced and highstand facies tracts. Maximum transgression occurred during deposition of the lowest part of the upper member, synchronous with the putatively eustatic Claggett highstand in other parts of the Western Interior Basin. The sequence boundary is placed at the base of the overlying capping sandstone member, diagnosed by a major shift in petrography and paleocurrent direction, as well as up to 4 m of fluvial incision into the underlying upper member. The capping sandstone member is interpreted as the amalgamated fluvial facies tract, and the sequence boundary at the base of the capping sandstone is regarded as tectonically induced. Improved geochronology in the formation now permits high-resolution correlation with marine units to the east and along-strike correlation with contemporaneous alluvial units up and down the western margin of the Western Interior Basin.

Answer 1

改进的年龄的限制Wahweap形成表明,中层和上层成员在eustatic Claggett沉积(T8的罪过Kauffman 1977)相邻西方内部产生。此外,相分析形成的Wahweap透露增加两个砂泥比和程度,上部砂岩融合中成员基地的限制,这表明逐渐减少砂岩在一代的住宿在盆子里。最近的冲积层序地层模式后,中间的成员被解释为孤立的河流相沉积的系统,而上部会员代表和高位域潮汐地被影响相。最大海侵发生在沉积最低的上层部分成员,同步与拍摄Claggett高位eustatic国内其他地区的西方室内盆。边界被放置在序列的基础上覆盖砂岩成员,一个主要的转变为在岩石和运用地层厚度方向,以及4米高的流水下切上潜在的会员。盖砂岩的成员被解释为合并的河流相沉积的道,边界和序列在该基地的盖砂岩作为构造诱发。改进的同位素地质年代学形成现在允许高分辨率相关与海洋单位东部和along-strike相关性,而与同时代的冲积单位的西缘上下西方室内盆。

改进对Wahweap形成年龄的限制表明，中部和上部成员在海平面Claggett侵在相邻的西部内陆海道（考夫曼1977年的T8）交存。此外，相的Wahweap形成分析显示，在两个砂增加：泥比和砂岩合并从中间成员的上限砂岩基地上部程度，预示着在住宿一代逐渐减少盆地。在最近的冲积层序地层模型，中间的成员被解释为孤立道河流相，而上部的成员代表了潮汐影响和高位相大片。最大海侵过程中出现的上层成员，这种公认海平面Claggett在西部内陆盆地其他地区高水位同步的最低部分沉积。该序列的边界被放置在覆盖砂岩成员由在岩石学和古水流方向的重大转变，以及成底层的上段为4米的河流切口诊断的基础。加盖砂岩成员被解释为合并后道河流相，以及在封盖砂岩碱基序列的边界被视为构造引起的。改进的年代学的形成与现在允许单位到东部海洋高分辨率关联和沿罢工与同期相关单位和冲积下来的西部内陆盆地西缘。
