Badlands are a type of dry terrain where softer sedimentary rocks and clay-rich soils have been extensively eroded. [1] They are characterized by steep slopes, minimal vegetation, lack of a substantial regolith, and high drainage density. [2] Ravines, gullies, buttes, hoodoos and other such geologic forms are common in badlands.
Badlands National Park. The geology of South Dakota began to form more than 2.5 billion years ago in the Archean eon of the Precambrian.Igneous crystalline basement rock continued to emplace through the Proterozoic, interspersed with sediments and volcanic materials.
Badlands National Park (Lakota: Makȟóšiča [3]) is a national park of the United States in southwestern South Dakota. The park protects 242,756 acres (379.3 sq mi; 982.4 km 2 ) [ 1 ] of sharply eroded buttes and pinnacles , along with the largest undisturbed mixed grass prairie in the United States.
The Bisti/De-Na-Zin Wilderness is the largest area of badlands in the San Juan Basin that is easily accessible to the public. [7] The badlands expose the longest, most complete, and most richly fossiliferous sequence of beds spanning the Cretaceous-Paleogene boundary in any single sedimentary basin in the world. [8]
The Bardenas Reales (sometimes referred as Bárdenas Reales) is a semi-desert natural region, or badlands, of some 42,000 hectares (420 km 2; 104,000 acres) in southeast Navarre . The soils are made up of clay , chalk , and sandstone and have been eroded by water and wind creating surprising shapes, canyons, plateaus, tabular structures, and ...
The Hell Creek Formation is an intensively studied geological formation of mostly Upper Cretaceous and some Early Paleocene rocks in North America, named for exposures studied along Hell Creek, near Jordan, Montana. The formation stretches over portions of Montana, North Dakota, South Dakota, and Wyoming.
The word 'malpaís' in Spanish translates to "badland," and this describes the area as being extremely rough and difficult to traverse and unusable for crops.Although a malpaís is often another word for the badlands that form by erosion of sedimentary rocks in the same environment, a malpaís is often associated with such types of lava plain terrain as found in a volcanic field.
The Chinle Formation is an Upper Triassic continental geological formation of fluvial, lacustrine, and palustrine to eolian deposits spread across the U.S. states of Nevada, Utah, northern Arizona, western New Mexico, and western Colorado. In New Mexico, it is often raised to the status of a geological group, the Chinle Group.
