The Oquirrh-Wood River Basin is a Pennsylvanian to Permian clastic and carbonate basin in northwestern Utah and southern Idaho, USA. The basin is commonly considered the northwesternmost expression of the Ancestral Rocky Mountains (ARM). Basin fill is locally up to 9 km thick. Facies range from shelf carbonates to deep marine debrites, and generally deepen from basin initiation to the beginning of the Permian. Unlike other ARM basins, no basin-bounding fault or highland has been identified as the source of these thick deposits and the tectonic drivers of basin subsidence are poorly understood.

Tectonic subsidence analysis was performed on 10 stratigraphic sections across the basin, resulting in a two-phase tectonism model. Pennsylvanian subsidence is interpreted as being related to strike-slip deformation; whereas Permian subsidence in the western part of the basin may be related to the uplift and unconformity sequence documented in northeastern Nevada.

Detrital zircon geochronology and thin section point counts are relatively uniform in Middle Pennsylvanian and early Permian samples, suggesting local tectonism did not alter dominant sediment routing patterns. Oquirrh Group sandstones are compositionally mature and contain sparse feldspar or lithic grains, leading to the interpretation that sample sediments were derived from recycled orogenic sources. UPb ages on detrital zircons from three Pennsylvanian and three Permian samples suggest sediment was overwhelmingly derived from multiple Laurentian basement provinces to the north and east, consistent with interpretations from the Wood River Basin. Paleocurrent data indicate a prevailing southward ocean current, suggesting a combination of sediment recycling and sediment transport across Laurentia from orogenic highlands in the northeast to the Oquirrh-Wood River Basin throughout the late Paleozoic.

奥奎尔伍德河流域是宾夕法尼亚州至二叠纪碎屑岩和碳酸盐岩盆地，位于犹他州西北部和美国爱达荷州南部。该盆地通常被认为是祖先落基山脉 (ARM) 最西北部的表现。盆地填充局部可达 9 公里厚。相范围从陆架碳酸盐岩到深海碎屑岩，通常从盆地开始到二叠纪开始加深。与其他 ARM 盆地不同，没有盆地边界断层或高地被确定为这些厚沉积物的来源，并且对盆地沉降的构造驱动因素知之甚少。

对整个盆地的 10 个地层剖面进行了构造沉降分析，产生了一个两相构造模型。宾夕法尼亚州的沉降被解释为与走滑变形有关；而盆地西部的二叠纪沉降可能与内华达州东北部记录的隆起和不整合序列有关。

宾夕法尼亚中期和二叠纪早期样品的碎屑锆石年代学和薄片点计数相对均匀，表明局部构造作用没有改变主要的沉积物路径模式。Oquirrh Group 砂岩成分成熟，含有稀疏的长石或岩屑颗粒，因此可以解释为样品沉积物来自循环造山源。你来自三个宾夕法尼亚州和三个二叠纪样本的碎屑锆石的铅年龄表明沉积物绝大多数来自北部和东部的多个劳伦基底省，这与伍德河流域的解释一致。古洋流数据表明盛行的南洋流，表明整个晚古生代期间，沉积物再循环和沉积物从东北造山高地到 Oquirrh-Wood 河流域的沉积物运输相结合。
