| 説明 | Faults are fractures in rocks along which there has been differential displacement. Fault movement is usually in the form of sudden jolts - this sends out shock waves, which results in earthquakes. Compressional stress produces reverse faults and thrust faults. Extensional stress produces normal faults. Shear stress produces transform faults.Seen here is a reverse fault between structurally-tilted, reddish sandstone spires of the Lyons Sandstone (= upper left) and tilted siliciclastics of the Fountain Formation (= lower right). The fault plane dips to the east (= to the left in this shot).Stratigraphy: lower Lyons Sandstone (~mid-Permian) over Fountain Formation (Pennsylvanian to Permian)Locality: looking south at the northern end of North Gateway Rock, Garden of the Gods, northwestern side of the town of Colorado Springs, northeast of Manitou Springs, western El Paso County, central Colorado, USA (vicinity of 38° 52’ 51.33” North latitude, 104° 52’ 53.94” West longitude) |
