A gypsum occurrence located in the NE¼ sec. 18, T9N, R20E and/or secs. 27, 28, 33 & 34, T9N, R20E, G&SRM, approximately 25.2 km (15.7 miles) E of Cibecue and 8-10 miles W of US highway 60. The USGS MRDS database stated accuracy for this location is 1,000 meters.

Mineralization is massive beds of gypsum to 40 aggregate feet thick hosted in the Late Permian reddish siltstone of the Upper Supai Formation, upper block, upper Gypsum Zone. There are 2 gypsum zones of 16 & 18 feet thick, separated by 2 to 3 feet of reddish siltstone. Local rocks include Permian to Pennsylvanian sedimentary rocks and/or Oligocene to Paleocene[?] sedimentary rocks.

Regional Geology

This geological map and associated information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This does not necessarily represent the complete geology at this locality but it gives a background for the region in which it is found.

Rupelian - Danian
28.1 - 66 Ma



ID: 2989032
Oligocene to Paleocene[?] sedimentary rocks

Age: Paleogene (28.1 - 66 Ma)

Stratigraphic Name: Chuska Sandstone

Description: "Rim gravels". Light colored, weakly to moderately consolidated conglomerate and sandstone deposited largely or entirely before mid-Tertiary volcanism and extensional faulting. Most sediment was deposited by early Cenozoic streams that flowed northeastward onto the Colorado Plateau from areas to the southwest that are now lower in elevation than the Plateau. Sediments of this map unit, other than the Chuska Sandstone in northeasternmost Arizona, are commonly referred to as "rim gravels" because they now rest on or near the Mogollon Rim, which is the southwestern edge of the Colorado Plateau. (30-65 Ma)
