Fe Rift Geologic Province (modified after Gautier et al., ). Stratigraphy The Albuquerque-San Luis Rift Basin contains rocks ranging in age from Precambrian to Recent (Fig. P-5). Most of the basin fill consists of thick deposits of nonmarine synrift sedimentary rocks and interca lated volcanic rocks, especially in the lower part. The San Luis Basin is the largest of the basins comprising the northern Rio Grande rift; the southern portion underlies mainly Pliocene rocks of the Taos Plateau volcanic field of northern New Mexico. The fault-bound basin includes thick accumulations of Santa Fe Group rift sediments and syn-rift .

The Rio Grande rift is a north-trending continental rift zone. It separates the Colorado Plateau in the west from the interior of the North American craton on the east. The rift extends from central Colorado in the north to the state of Chihuahua, Mexico, in the south.
The rift zone consists of four basins that have an average width of 50 kilometers. The rift can be observed on location at Rio. The Española basin, part of the Rio Grande rift in northern New Mexico, contains sedimentary and volcanic rocks of Eocene to Quaternary age.
The onset of rifting, based on evidence from north and south of the basin, is generally considered middle to late by: Crustal structure of the western margin of the Rio Grande rift and Mogollon-Datil volcanic field, southwestern New Mexico and southeastern Arizona Author(s) Robert V. Schneider.
Geophysical constraints on Rio Grande rift structure in rate compared to the northern and southern zones and/or reﬂ ects Precambrian rock crops out or has been encountered in boreholes.
The Albuquerque Basin, located in the central portion of the Rio Grande rift, is filled by 7, m of Tertiary clastic sediments deposited on a “basement” of Mesozoic and Paleozoic sedimentary rocks and Precambrian crystalline rocks. The basin has been a center of. The Rio Grande Rift The crustal structure of the Rio Grande Rift has been interpreted from gravity data, seismic reflection and refraction profiles, and earthquake data (Sanford et al., ; Ramberg et al., ; Olsen et al., ; Cook et al., ; Keller et al., ).
The San Luis Valley (SLV) of south-central Colorado is a major physiographic and structural element of the Rio Grande rift. The valley measures. The apparent doming of the km/s layer in the north-central Embayment suggests that rifting may be the result of a triple junction located in the Reelfoot Basin area.
The crustal structure of the Mississippi Embayment is compared to other continental rifts: the Rhinegraben, Limagnegraben, Rio Grande Rift, Gregory Rift, and the Salton Trough. At this latitude, it is probably the major Rio Grande rift structure. In fact, gravity modeling has determined that the thinnest crust (above 32 km) in the region lies beneath the north Tularosa basin.
Analysis of gravity and magnetic anomaly maps identify gravity lows associated with Paleozoic or Precambrian basins. Broadband and long-period magnetotelluric data were acquired over the northern part of the Cambay rift zone along an east–west profile ~ km in length.
The decomposed TE- and TM-mode data were inverted using a 2-D nonlinear conjugate gradient algorithm to obtain the lithospheric structure of the region. A highly conductive (~ S) layer was identified within the Cambay rift zone and. Rift processes --Rio Grande rift: problems and perspectives / W.

The northern Rio Grande rift is composed of three major basins; from north to south they are the San Luis, Espanola and Albuquerque–Belen basins. Movement on these faults has resulted in only minor tilting and rotation of rocks within the Rio Grande rift.
Discussion The fact that the main episode of faulting in the Espanola basin began about 10 m.y. ago, but uplift and doming of the northern and central Rio Grande rift did not occur until ~7 m.y.

The crustal structure of the Mississippi Embayment is compared to other continental rifts: the Rhinegraben, Limagnegraben, Rio Grande Rift, Gregory Rift, and the Salton Trough.
This comparison suggests that alteration of the lower crust is a ubiquitous feature of continental rifts, INTRODUCTION. The Precambrian core of the Tenmile Range is continuous across Tenmile Canyon with the core of the southern Gore Range, but Tenmile isn't just another Laramide faulted no doubt rose in Laramide time, but it probably rose more, via normal faulting and mantle-related uplift, with the east shoulder of the Rio Grande Rift in late Tertiary time, more than 20 Ma after the main pulse of.

INFLUENCE OF BASEMENT STRUCTURE ON SHALLOW AQUIFER GEOCHEMISTRY IN THE RIO GRANDE RIFT, NORTHERN NEW MEXICO— EXAMPLES FROM THE SANTA FE AND PEÑASCO EMBAYMENTS OF THE ESPAÑOLA BASIN P. Johnson, [email protected], New Mexico Bureau of Geology and Mineral Resources. Precambrian - Precambrian - Precambrian geology: By international agreement, Precambrian time is divided into the Archean Eon (occurring between roughly billion years ago and billion years ago) and Proterozoic Eon (occurring between billion and million years ago).
After the Precambrian, geologic time intervals are commonly subdivided on the basis of the fossil record. Even though Precambrian rocks represent more than 80% of the rock history of Earth, and constitute 17% of Earth's land surface, our knowledge of Precambrian geology is wistfully incomplete.
In the Taos area, Precambrian rocks compose most of the highest mountain peaks, and include a wide variety of rock types and ages. Geophysical expression of buried range-front embayment structure: Great Sand Dunes National Park, Rio Grande rift, Colorado. Great Sand Dunes National Park and Preserve (GRSA, Colorado) lies along the eastern margin of the San Luis Basin and the tectonically active Sangre de Cristo fault system that are part of the northern Rio Grande rift.Tuesday, Decem The area is dominated by Precambrian igneous rocks and lower Paleozoic carbonates, but Cenozoic () intrusions are also recognized.
Thin sections and rock slabs were used to describe and identify many of the lithologic units. The Franklin Mountains are often referred to as a simple fault block mountain range related to the Rio Grande Rift.
