Ogallala formation

In cooperation with the North Plains Groundwater Conservation District (NPGCD), the U.S. Geological Survey collected and analyzed water-quality samples at 30 groundwater monitor wells in the NPGCD in the Texas Panhandle. All of the wells were completed in the Ogallala Formation of the central High Plains aquifer. Samples from each well were collected during February-March 2012 and in March 2013..

These strata comprise the majority of sediments in the High Plains aquifer, the primary source of groundwater in the Southern and Central Great Plains. The Quaternary deposits of the Southern High Plains are primarily windblown sandy silt and shallow lake sediments.Chert. The rock within the Ogallala formation here referred to as chert occurs as irregular areas of uneven or spotty silicification of "caliche" or "marl" that contain various amounts of silt or sand. Smith (1940, p. 46) has described an exposure of this chert in western Clark County as follows:

The member names for the Ogallala Formation (including the Valentine, Ash Hollow, and Kimball) in Kansas of Zeller (1968) are abandoned.

Elsewhere the Niobrara is overlain disconformably by the Ogallala Formation (Miocene and Pliocene) at a contact that truncates the formation from west to east, or by unconsolidated Quaternary deposits.

Texas contains a wide variety of geologic settings. The state's stratigraphy has been largely influenced by marine transgressive-regressive cycles during the Phanerozoic, with a lesser but still significant contribution from late Cenozoic tectonic activity, as well as the remnants of a Paleozoic mountain range.the contact between the Ogallala and pre-Ogallala (probably Brule) Formations exposed on the east side of Rush Creek. Beds of dilt, sand, siltstone, and volcanic ash in the area locally dip to the northwest at angles of up to 8g0. The contact between the two formations cannot be seen on the west side ofis located along a paleo-channel of the Ogallala formation (locally known as the Slaton Channel) approximately 48.3 km (30 miles) southeast of Lubbock, TX. In an attempt to beneficiate the 25.4-mm (1-in.) concrete aggregate product, a log washer was installed in the processing line to liberate and remove fines (clay) from the finished product.
