Precambrian rocks crop out across approximately five percent of New Mexico and underlie the entire state. The rocks now exposed at the surface were uplifted during the Paleozoic , the early Cenozoic Laramide orogeny as well as block faulting and tilting in the more recent geologic past.
Pha. Had. / 36.246; -105.745. The Hondo Group is a group of geologic formations that crops out in most of the Precambrian -cored uplifts of northern New Mexico. Detrital zircon geochronology gives a maximum age for the lower Hondo Group of 1765 to 1704 million years ( Mya ), corresponding to the Statherian period .
Ortega Formation. Pha. Had. / 36.441°N 106.074°W / 36.441; -106.074. The Ortega Formation is a geologic formation that crops out in most of the mountain ranges of northern New Mexico. Detrital zircon geochronology establishes a maximum age for the formation of 1690-1670 million years ( Mya ), in the Statherian period of the Precambrian.

The Caballo Mountains, (Spanish: "horse") are a mountain range located in Sierra and Doña Ana Counties, New Mexico, United States. The range is located east of the Rio Grande and Caballo Lake, and west of the Jornada del Muerto; the south of the range extends into northwest Doña Ana County. The nearest towns are Truth or Consequences and Hatch.
Year defined. 1953. Vadito Group (New Mexico) Map of Vadito Group outcroppings. The Vadito Group is a group of geologic formations that crops out in most of the Precambrian -cored uplifts of northern New Mexico. Detrital zircon geochronology and radiometric dating give a consistent age of 1700 Mya for the group, corresponding to the Statherian ...
Moppin Complex. Pha. Had. / 36.724; -106.238. The Moppin Complex is a Precambrian geologic complex found in the Tusas Mountains of northern New Mexico. It has not been directly dated, but is thought to be Statherian based on a minimum age of 1.755 Gya from radiometric dating of magmatic intrusions.
