The Wahweap Formation is an ~ 400-m-thick succession of fluvial and estuarine channel sandstones and floodbasin mudstones divided into lower, middle, upper, and capping sandstone members. Facies analysis of the Wahweap Formation on the Kaiparowits Plateau reveals the presence of ten facies associations grouped into channel and floodbasin deposits. Facies associations (FAs) from channels include: (1) single-story and (2) multistory lenticular sandstone bodies, (3) major tabular sandstone bodies, (4) gravel bedforms, (5) low-angle heterolithic cross-strata, and (10) lenticular mudrock, whereas floodbasin facies associations include: (6) minor tabular sandstone bodies, (7) lenticular interlaminated sandstone and mudrock, (8) inclined interbedded sandstone and mudrock, and (9) laterally extensive mudrock.
The lower and middle members are dominated by floodbasin facies associations. The lower member consists dominantly of FA 8, interpreted as proximal floodbasin deposits including levees and pond margins, and is capped by a persistent horizon of FA 3, interpreted as amalgamated channel deposits. FAs 4 and 6 are also present in the lower member. The middle member consists dominantly of FA 9, interpreted as distal floodbasin deposits including swamp, oxbow-lake, and waterlogged-soil horizons. FAs 1, 2, 5, 6, 7, 8, and 10 are present in the middle member as well, which together are interpreted as evidence of suspended-load channels. The upper member is sandstone-dominated and consists of FAs 1, 2, 3, 5, 7, and 8. FAs 5 and 7, which occur at the base of the upper member, are interpreted as tidally influenced channels and suggest a marine incursion during deposition of the upper member. The capping sandstone is characterized by FAs 3, 4, and 6, and is interpreted to represent a major change in depositional environment, from meandering river systems in the lower three members to a low-accommodation, braided river system.

Wahweap（美国地名）结构是400米厚的，一个由连续的河流、河口的河道砂岩和洪水流域泥岩组成的岩土结构。它可分为下层、中层、上层以及顶层砂岩。对Kaiparowits高地上的Wahweap结构的分相分析揭示了在河道砂岩和洪水流域沉积存在十个相的组合结构。这十个相组分包括：河道砂岩的(1)单层 ，(2)多层透镜状砂岩体，(3)大板状砂岩体，(4)河床砂砾，(5)低角度不规整交错地层，(10)透镜状泥砂；以及洪水流域泥岩的(6)小板状砂岩体，（7）透镜状夹层砂岩和泥砂，（8）倾斜状夹层砂岩和泥砂，和（9）侧向延伸泥砂。
下层和中层砂岩主要成分是洪水流域泥岩相。下层成分主要是相组分8，也被称作近似洪水流域沉积，例如河堤和池塘边缘区域，它被稳固的相组分3层覆盖，这就是合并河道沉积。相组分4和6也出现在下层成分区。中层的主要成分是俗称 洪水流域末端沉积的相组分9，包括沼泽区，U型湖和渍水土层。相组分1、2、5、6、7、8和10都出现中层区出现，这是可被视为悬浮泥砂河道的证据。上层的主要成分是砂岩，它由相组分1、2、3、5、7和8组成。相组分5和7出现在上层区的底部，它们被视作受潮汐影响的河道，暗示了在上层成分沉积过程中有海水倒灌现象发生。顶部砂岩有相组分3、4和6，它是沉积环境发生大改变的一个象征, 从最初处于下面三层（下、中、上层）的蜿蜒河流系统，一直到低可容纳空间的分叉河流系统。

这是岩层方面的研究吧。
