Dakota sandstone.

The Cloverly Formation in Wyoming, which is equivalent to the Dakota Sandstone, is an important aquifer. Because the sandstones of the Dakota aquifer receive some recharge at high altitudes and some by upward leakage from deeper aquifers, the water in the aquifer is under high artesian pressure. When development of the Dakota aquifer began in ...

Stratigraphic terminology of the Dakota Sandstone and Mancos Shale, west-central New Mexico Bulletin 1372-J By: Edwin R. Landis , C. H. Dane , and William Aubrey CobbanThe sandstone originated from sand deposited on the floor of an ancient ocean. (A historical marker located in Sioux Falls in Minnehaha County, South Dakota.) 1.2 billion years ago intense heat and pressure transformed pure quartz sandstone into quartzite rock. The sandstone originated from sand deposited on the floor of an ancient ocean.From introduction: In 1978 the U.S. Geological Survey began a 4-year study of aquifers in the northern Great Plains. The purpose of this map, which is a product of that study, is to show the altitude of the top of the "Dakota sandstone" (drillers' term).The Dakota Sandstone stores gas in offshore marine sandstones trapped by marine shales. Fracturing is required to source these units. The Pictured Cliffs Sandstone consists of regressive-marine deposits, where gas is stored in porous sandstones and trapped by mud- or siltstones. Production depends on natural fractures throughout unit. the Dakota sandstone contains members which may be equiva­ lents of the Lakota sandstone and the Fuson shale. Pre- Cretaceous formations are the Sioux quartzite of Precam­ brian age, and an unnamedj crystalline rock of inferred Precambrian age. Deposits of Pleistocene and Recent age mantle the bedrock ...

The Navajo Sandstone consists of thick layers of cross-bedded sandstone formed by windblown sand dunes in a vast ancient desert.

Thus, the term included not only Dakota sandstone as it had been previously defined, but also Cheyenne and Kiowa ...

Benton formation. The Dakota sandstone, consisting of the Lytle and South Platte formations, is more resistant than either the Morrison or Benton formations, and as a result the group crops out as a hogback or cuesta. Floristically the Dakota sandstone lies along the transition zone between the lower montane forest, in which Pinus ponderosa Laws.The approximate age for Dakota sandstone for Watch formation is about 70 million years; there are glacial deposits of Pleistocene age. 12. based on the level of viscosity; higher viscosity generally leads to very peak on volcanic surfaces.
