The Mineralogy And Paragenesis Of The Lone Star Deposit, Santa Fe County, New Mexico, Lawrence K. Lustig
The Mineralogy And Paragenesis Of The Lone Star Deposit, Santa Fe County, New Mexico, Lawrence K. Lustig
Earth and Planetary Sciences ETDs
The Lone Star deposit is located in La Bajada Canyon in western Santa Fe County, New Mexico. The exposed sedimentary rocks of the area range in age from the Cretaceous to recent. Four unconformities are present which are the result of erosional levels established during the Tertiary. The host rock of the deposit is the Cieneguilla liburgite formation. The Cieneguilla consists mainly of thin embedded limburgite flows and conglomerate of Miocene age. The Lone Star deposit lies in this conglomerate at a depth of approximately 150 feet from the top of the Cieneguilla.
The Geology Of The Tecolote Hills Area, Lincoln County, New Mexico, Donald E. Rawson
The Geology Of The Tecolote Hills Area, Lincoln County, New Mexico, Donald E. Rawson
Earth and Planetary Sciences ETDs
The Tecolote Hills in the north-central Lincoln County, New Mexico, consist of Permian, Triassic, and Cretaceous sedimentary strata intruded by early Tertiary (?) sills, dikes, and laccoliths. A partial section of the Permian Yeso formation, measured thickness 380 feet, is exposed and is overlain conformably by the Glorieta sandstone member of Permian San Andres formation. This sandstone thins, at least locally, to the south and intertongues with San Andres limestone. The maximum thickness of the Glorieta sandstone is about 215 feet. It is overlain by a 300-foot thickness of San Andres rocks, further divisible into a lower limestone member and …
Insoluble Residue Study Of Pennsylvanian Strata Exposed In San Juan Canyon, San Juan County, Utah, James A. Smith
Insoluble Residue Study Of Pennsylvanian Strata Exposed In San Juan Canyon, San Juan County, Utah, James A. Smith
Earth and Planetary Sciences ETDs
The purpose o! this investigation is to correlate strata in the Pennsylvanian rocks exposed in the canyon of the San Juan River from Raplee anticline to Slickhorn Gulch through a binocular study cf rock samples and their insoluble residues. Three days were spent in field reconnaissance. Laboratory study included preparation of a photo geological map and a detailed jnsoluble residue cross section of the area investigated.
Correlation Of Reef Calcarenites Of The Pennsylvanian Paradox Formation, San Juan County, Utah, Jack Jordan
Correlation Of Reef Calcarenites Of The Pennsylvanian Paradox Formation, San Juan County, Utah, Jack Jordan
Earth and Planetary Sciences ETDs
This thesis is a summation of lithologic analyses of three stratigraphic sections: the Danvers 1-X Harris-Federal test, the Honaker Trail locality, and the Raplee locality in San Juan Canyon, San Juan County, Utah (FIg. 1) In these localities, the Paradox Formation as defined by Wengerd and Strickland (1954, p.2169) has been studied, inasmuch as the formation is known to contain limestone bioherms ("reefs") (Wengerd, 1951) in conjunction with biostromal strata.
