Geology Of The Northern Part Of The Fra Cristobal Range, Sierra And Socorro Counties, New Mexico, John T. Mccleary

Earth and Planetary Sciences ETDs

The northern part of the Fra Cristobal Range contains rocks of Precambrian, Cambrian, Pennsylvanian, Permian, Cretaceous, Tertiary and Quaternary age. One of the northernmost exposures in New Mexico of the Cambrian Bliss formation occurs in the central part of the range. Here the bliss formation wedges out due to widespread pre-Pennsylvanian erosion which removed all the other lower Paleozoic rocks.

The Pennsylvanian Magdalena group, which is predominately limestone, rests uncomformably on Precambrian rock and the Bliss Formation. It forms the greatest part of the sedimentary sequence and is divided into three formations; the Red House, Nakaye, and Bar B formations …

Lithogenesis Of The Pennsylvanian Madera Formation Of Palomas Peak, Sandia Mountains, New Mexico., Ronald D. Perkins

Earth and Planetary Sciences ETDs

The Pennsylvanian Madera formation of Palomas Peak in the Sandia Mountains of central New Mexico is a sequence of marine limestone and minor sandstone that ranges in age from Desmoinesian to Virgilian. The limestone is predominantly clastic or bioclastic and the sandstone is arkosic. Lithologic and paleontologic evidence suggests an epineritic to infraneritic environment on a gently subsiding shelf during deposition of the Madera Sediments.

Rhythmic deposition at Palomas Peak is evidenced by alternating clastic and bioclastic limestones which may have resulted from: (1) eustatic changes in sea level, (2) tectonic fluctuations in the downwarping of the shelf, or (3) …

The Jurassic Todilto Formation Of New Mexico, Henry O. Ash

Earth and Planetary Sciences ETDs

The Todilto formation of New Mexico is a widespread and distinctive Jurassic unit confined to the northern one-half of the State and adjacent parts of Arizona and Colorado. It consists of a lower Limestone member and an upper Gypsum member. The Gypsum member also contains some limestone. The two members are not coextensive in area. Both are present in the central part of the area in which the formation is found, but the Limestone member extends far beyond the limits of the Gypsum member.

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

Microstratigraphic And Sedimentational Studies Of An Early Man Site Near Lucy, New Mexico, Jerry Harbour

Earth and Planetary Sciences ETDs

The purpose of the study has been to interpret the sedimentary record of the Lucy site deposits in order to establish a climatic sequence into which various cultural zones, especially the Sandia, may be placed, and to date this climatic sequence as accurately as possible. A second purpose has been to establish the reliability of the Pleistocene Lake Estancia shore levels as a regional floating chronology of climatic events, and to correlate the Lucy site sediments with this regional chronology. By means of the Lucy site artifacts, this chronology is partly fixed in time, so as a result of the …

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. …

Geology And Ground-Water Resources Of The Portales Valley Area, Roosevelt And Curry Counties, New Mexico, Sherman E. Galloway

Earth and Planetary Sciences ETDs

Since 1910, and particularly since the closing years of World War II, considerable development of the ground water occurring in the valley fill has been made for irrigation purposes. This increase in development has resulted in a progressive decline of the water levels in this area. The results of this study indicate that the water occurring in the valley fill is the only water of good chemical quality occurring in the Portales Valley that can be obtained in quantities that are sufficient for normal irrigation, municipal, industrial, stock, and domestic uses, and that if the present rate of ground water …
