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.
Hondo Group (New Mexico) Map of Hondo Group outcrops. 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.
The Mazatzal orogeny was an orogenic event in what is now the Southwestern United States from 1650 to 1600 Mya [1] in the Statherian Period of the Paleoproterozoic. Preserved in the rocks of New Mexico and Arizona, it is interpreted as the collision of the 1700-1600 Mya age [1] Mazatzal island arc terrane with the proto-North American continent ...
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 ...
1937. Ortega Formation (New Mexico) Ortega Formation outcrops in New Mexico. 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.
During the Paleozoic, western North America lay underneath a shallow sea, which deposited many kilometers of limestone and dolomite. [7]In the southern Rocky Mountains, near present-day Colorado and New Mexico, the Precambrian and Paleozoic rocks were disturbed by mountain building approximately 300 Ma, during the Pennsylvanian.
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.
