| 説明 | This is the upper part of a nice Precambrian-Cambrian unconformity section in Manitou Springs, Colorado. The light-colored unit at top is a Lower Ordovician, shallow marine fossiliferous limestone unit called the Manitou Limestone. The dark reddish-colored rocks below are the Peerless Formation, which here consists of shallow marine quartzose sandstones with dolomite. The Manitou-Peerless contact is a disconformity.Stratigraphy: Manitou Limestone (Lower Ordovician) over Peerless Formation (Upper Cambrian)Locality: roadcut along the western side of Manitou Avenue (= Business Route 24), northwestern side of the town of Manitou Springs, west of Colorado Springs, western El Paso County, central Colorado, USA (38° 52’ 08.02” North latitude, 104° 55’ 31.83” West longitude) |
