Summary
editDescriptionFault in redbeds (Chugwater Formation, Upper Triassic; Red Hill, Seminoe Mountains, Wyoming, USA) 4.jpg |
English: Faulted redbeds in the Triassic of Wyoming, USA. (looking ~east)
Redbeds are hematite-rich siliciclastic sedimentary rocks (shale, siltstone, sandstone, conglomerate). Hematite is iron oxide, Fe2O3. Redbeds become common in the rock record starting at about 1.8 billion years ago, in the late Paleoproterozoic. At that time, atmospheric oxygen (O2) levels were high enough to result in "rusting" of iron at Earth's surface. Redbeds are especially common in nonmarine Permian and Triassic successions. Seen here are redbeds of Late Triassic age in Wyoming. The red rocks are shales. The light-colored horizon is sandstone. Notice that the sandstone is offset by faulting. A ~northwest-striking fault with about 1.5 kilometers of aerial offset occurs adjacent to this outcrop. This is likely a minor splay fault. The thick black line is my interpretation of the fault trace. Stratigraphy: Chugwater Formation, Upper Triassic Locality: roadcut on the eastern side of Seminoe Road (Route 357) at Red Hill, west of Seminoe Reservoir, southern flanks of the Seminoe Mountains, northern Carbon County, south-central Wyoming, USA (42° 07' 44.36" North latitude, 106° 54' 41.43" West longitude) |
