Ancestral and early Pueblo peoples have lived in the Sandia Mountains area for thousands of years. [citation needed] Examples of previous Pueblo settlements, now unoccupied, include Tijeras Pueblo and Pa'ako Pueblo, both founded around 700 years ago. Sandia Pueblo is a modern pueblo, abutting the Sandia Mountains on the northwest side of the ...
[2] [3] It is found in the Sandia, Jemez, [4] Sangre de Cristo, [3] and Manzano Mountains [1] as well as the Las Vegas Basin. [ 3 ] The formation rests on Precambrian basement rock in the Sandia Mountains, but is underlain by Osha Canyon Formation in the southern Jemez Mountains or by formations of the Arroyo Penasco Group in the Sangre de ...
Shaded relief map of the Llano Estacado. 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.
Flanking mountains are generally taller along the east side of the rift (although some of this relief may be Laramide in origin). [1] The thickness of the crust increases to the north beneath the rift, where it may be as much as 5 kilometres (3.1 mi) thicker than it is in the south. The crustal thickness underneath the rift is on average 30 ...
The pluton lies in the southern Sandia Mountains, with Sandia granite to the northwest and Seven Springs shear zone to the south. The pluton may include three compositionally distinct phases: a fine-grained, peraluminous, two-mica leucogranite with a radiometric age of 1632±45 Ma, a medium-grained equigranular monzogranite with a radiometric age of 1659±13 Ma, and a generally coarse-grained ...
Sandia Mountain Wilderness, part of Cibola National Forest, is located east of Albuquerque, New Mexico, and comprises much of Sandia Mountains. It became part of the National Wilderness Preservation System in 1978 by an act of the United States Congress and has a total of 37,877 acres (15,328 ha).
Geologically, the Albuquerque Basin is a half-graben that slopes down towards the east to terminate on the Sandia and Manzano mountains. [2] The basin is the largest and oldest of the three major basins in the Rio Grande rift, [ 3 ] containing sediments whose depth ranges from 4,407 to 6,592 meters (14,459 to 21,627 ft).
Sandia Granite with xenolith. The Sandia granite is prominently exposed along the east flank of the Rio Grande rift, with almost 1.5 kilometres (4,900 feet) of exposure at Sandia Crest. It extends from Placitas to Tijeras Canyon. Its radiometric age is 1453±12 Ma. [1] The pluton is a single body with significant heterogeneities.
