The geologic history of the state began with its assembly during the Yavapai and Mazatzal orogenies 1750 to 1650 million years ago (Mya). This was followed by 200 million years of tectonic quiescence that ended in the Picuris orogeny. This event transformed the New Mexico crust into mature continental crust.
From the White Place, painting by Georgia O'Keefe depicting the Abiquiu Formation. The Abiquiu Formation is a geologic formation found in northern New Mexico. Radiometric dating constrains its age to between 18 million and 27 million years, corresponding to the late Oligocene to Miocene epochs.
Santa Fe, New Mexico. Named by. Hayden. Year defined. 1869. The Santa Fe Group is a group of geologic formations in New Mexico and Colorado. It contains fossils characteristic of the Oligocene through Pleistocene epochs. The group consists of basin -filling sedimentary and volcanic rocks of the Rio Grande rift, and contains important regional ...
Named by. W.T. Lee. Year defined. 1909. San Andres Formation, United States (New Mexico) San Andres Formation caps Sierra de la Cruz northeast of Socorro, New Mexico, USA. The San Andres Formation is a geologic formation found in New Mexico and Texas. It contains fossils characteristic of the late Leonardian (Kungurian) Age) of the Permian Period.
The unit was first defined by J.D. Sears in 1925 as the Gallup Sandstone Member of the Mesaverde Formation and named after Gallup, New Mexico, which is built partially on its uppermost bed. Sears originally defined the Gallup Sandstone as the three sandstone beds, separated by shale and coal beds, forming cliffs and hogbacks in the Gallup area ...
The Manzano Group is a group of geologic formations in central New Mexico. These have radiometric ages of 1601 to 1662 million years , corresponding to the late Statherian period of the Paleoproterozoic. The name Manzano Group was previously applied to a group of sedimentary formations of Permian age in roughly the same geographical area.
Hall Lake Formation. The Hall Lake Formation, formerly called the Hall Lake Member, is a geological formation in Sierra County, New Mexico preserving Lancian fauna, most notably dinosaurs. It is regarded as a member of the McRae Group, including the Elephant Butte and Staton-LaPoint locales. [2]
The Artesia Group is interpreted as a sequence of shelf rocks of the Capitan reef.It shows cyclicity and considerable lateral variation, from carbonate rocks near the Capitan reef, to mixed dolomitic mudstone, evaporites, and sandstones of a lagoon environment further from the reef, to a near-shore environment of evaporites, massive red siltstones, and minor amounts of dolomite.
