| 説明 | Redbeds with sediment-filled mudcrack in the Jurassic of Utah, USA.This is the Kayenta Formation, a mixed siliciclastics unit of mostly fluvial origin (= deposited in river systems). The bed at the very top is the basal Navajo Sandstone. The irregular vertical structure is a sediment-filled mudcrack. Given the width, depth, and spacing of these features at this outcrop, the mudcrack polygons are sizable (see also: www.flickr.com/photos/jsjgeology/32339908743).Stratigraphy: uppermost Kayenta Formation, Glen Canyon Group, Lower JurassicLocality: along Corona Arch Trail, just north of Bootlegger Canyon & just east of the Colorado River, west of the town of Moab, eastern Utah, USA |
