Geology Of The Southern Part Of The Ortiz Mountains Santa Fe County, New Mexico, John W. Peterson May 1958

Geology Of The Southern Part Of The Ortiz Mountains Santa Fe County, New Mexico, John W. Peterson

Earth and Planetary Sciences ETDs

The Ortiz Mountains lie in a belt of early Tertiary intrusive centers adjacent to the Rio Grande depression of north-central New Mexico. Tertiary organic activity and subsequent erosion have etched this mountain group into considerable relief.

Intrusive activity occurred during early Tertiary Espinaso time and resulted in emplacement of sills and dikes of a central stock. Correlation of volcanism with intrusive phases is difficult. Most volcansim probably occurred during the later part of Ortiz igneous activity. An elongate vent is exposed in the eastern part of the mountains and structurally occupies the highest position in the group.

The principle igneous …


Geology Of The Northern Part Of The Ortiz Mountains, Santa Fe County, New Mexico, Otis M. Mcrae Apr 1958

Geology Of The Northern Part Of The Ortiz Mountains, Santa Fe County, New Mexico, Otis M. Mcrae

Earth and Planetary Sciences ETDs

The northern part of the Ortiz Mountains of north-central New Mexico consists of a tilted fault block of Cretaceous Mancos shale and Mesaverde formation intruded by latite-andesite porphyry sills and laccoliths and a nepheline-bearing augite manzonite stock. Igneous activity started with the development of a volcanic vent in what is now the central part of the mountains. Volcanic debris from the vent want removed from the area by erosion and provided sedimentary material for the late [ ] Espinaso volcanics of the adjoining areas. Intrusion of the latite-andesite porphyry sills and laccolite followed extrusive igneous activity, as demonstrated by the …

Paleontology And Stratigraphy Of The Jemez Springs Area, Sandoval County, New Mexico, Bill P. Lovejoy Jan 1958

Paleontology And Stratigraphy Of The Jemez Springs Area, Sandoval County, New Mexico, Bill P. Lovejoy

Earth and Planetary Sciences ETDs

The Jemez Springs area of north-central New Mexico contains rocks ranging in age from Precambrian to Recent. Resting on Precambrian granite are 15 to 20 feet of Mississippian limestone and shale belonging to the Arroyo Peñasco formation of probable Meramecian age. The marine fauna is restricted to Pennsylvanian rocks. In this study. 64 species representing 40 genera were recognized, and the majority are illustrated and systematically described. Fossil evidence indicates a Lampasan (Atokan) age for the Sandia formation and a Desmoinesian, Missourian, and Virgilian age for the Madera limestone. Correlation was based primarily on the predominant and well-preserved brachiopod fauna. …

Preliminary Estimate Of The Underflow Across The South Dakota-Nebraska State Line In The Niobrara River And Ponca Creek Drainage Basins, E. C. Reed, C. F. Keech Nov 1957

Preliminary Estimate Of The Underflow Across The South Dakota-Nebraska State Line In The Niobrara River And Ponca Creek Drainage Basins, E. C. Reed, C. F. Keech

Conservation and Survey Division: Faculty and Staff Publications

The purpose of this paper is to estimate the amount of ground water flowing across the South Dakota-Nebraska State line within the Niobrara River basin, including the Ponca Creek basin. The study was made at the request of the Niobrara River Compact Commission. The estimates fiven in the paper are preliminary and subject to revision.

Geology Of The Canjilon Cauldron Sink Near Bernalillo, Sandoval County, New Mexico, Felix E. Mutschler May 1956

Geology Of The Canjilon Cauldron Sink Near Bernalillo, Sandoval County, New Mexico, Felix E. Mutschler

Earth and Planetary Sciences ETDs

Canjilon Hill is located on the west side of the Rio Grande, about 2 3/4 miles north-northwest of Bernalillo. Exposed on the hill is a local unit of breccia, conglomerate, and sandstone, which forms an elongate saucer-shaped body 4100 feet long, 2200 feet wide and 280 to 500+ feet thick. Unlike the underlying Santa Fe formation these strata contain an abundance of large angular basalt pebbles, cobbles, and boulders. In this paper these strata are termed the Canjilon formation of the Santa Fe group. Structural and sedimentological evidence suggest that the Canjilon formation was deposited in a subsidence depression initiated …

The Red Cloud Sand And Gravel, A New Pleistocene Formation In Nebraska, C. Bertrand Schultz, Eugene C. Reed, A. L. Lugn

Conservation and Survey Division: Faculty and Staff Publications

Recent studies of the stratigraphy and paleontology of the Pleistocene of Nebraska have resulted in additional data that require further clarification and partial revision of the Grand Island sand and gravel formation (1,2) in order that there may be no condusion as the results of varying usage of the term.


Geology Of The Southern Ladron Mountains, Socorro County, New Mexico, E.A. Noble Apr 1950

Geology Of The Southern Ladron Mountains, Socorro County, New Mexico, E.A. Noble

Earth and Planetary Sciences ETDs

The Ladron Mountains are in a fault-block range consisting in large part of Pre-Cambrian rocks. They are flanked on the west by Paleozoic sediments and elsewhere by Tertiary and Quaternary deposits. The Pre-Cambrian rocks of the southern Ladron Mountains consist of a thick sequence of quartzite and schist which has been granitized by a sub-adjacent intrusion to such a degree that only remnants of unaltered quartzite and schist remain, the remainder of the rocks being largely paragneiss and para-granite. The nature of the intrusion is not known, but it is suggested that it may have been at least partly formed …
