Reconnaissance Of The Quality Of Surface Water In The San Rafael River Basin, Utah, United States Geological Survey
Reconnaissance Of The Quality Of Surface Water In The San Rafael River Basin, Utah, United States Geological Survey
All U.S. Government Documents (Utah Regional Depository)
The water-quality reconnaissance of the San Rafael River basin, Utah, encompassed an area of about 2,300 square miles (5,960 square kilometers). Data were obtained by the U.S. Geological Survey one or more times at 116 sites from June 1977 to September 1978. At 19 other sites visited during the same period, the streams were dry. Precipitation and stream discharge were significantly less then normal during 1977 and ranged from less than to more than normal during 1978.

Results Of Test Drilling For Ground Water In The Southeastern Uinta Basin, Utah And Colorado, United States Geological Survey
All U.S. Government Documents (Utah Regional Depository)
During 1974, the U.S. Geological Survey began a comprehensive hydrologic study of the oil-shale area in the southeastern Uinta Basin of Utah and Colorado. From 1976 to 1978, six deep test holes were drilled principally to obtain information about aquifers in the Green River Formation of Tertiary age. Information obtained from the drilling project includes description of lithologic samples from core and drill cuttings, temperature and geophysical logs, drilling logs, packer tests, aquifer (pumping and recovery) tests, and analyses of water samples.

Contamination Of Boone-St. Joe Limestone Groundwater By Septic Tanks And Chicken Houses, Gerald D. Cox, Albert E. Ogden, Gretta Slavik
Contamination Of Boone-St. Joe Limestone Groundwater By Septic Tanks And Chicken Houses, Gerald D. Cox, Albert E. Ogden, Gretta Slavik
Journal of the Arkansas Academy of Science
Eighty-one water samples were collected from wells in the Boone-St. Joe limestone aquifer of northwest Arkansas and analyzed for fecal coliform, fecal streptococcus, total coliform bacteria, chloride, phosphate, nitrate and sulfate to determine the degree of contamination. Forty-nine percent of the samples had fecal streptococcus counts greater than 1 colony per 100 ml, 68% had total coliform counts of 1 or more colonies per 100 ml, and 9% of the wells had fecal coliform counts of 1 or more colonies per 100 ml. Water from wells in Clarksville, Nixa, Noark, Tonti and Waben cherty silt loam soils showed from 83 …
Stratigraphic Relationships Of The Brentwood And Woolsey Members, Bloyd Formation (Type Morrowan), Northwest Arkansas, Thomas A. Mcgilvery, Charles E. Berlau
Stratigraphic Relationships Of The Brentwood And Woolsey Members, Bloyd Formation (Type Morrowan), Northwest Arkansas, Thomas A. Mcgilvery, Charles E. Berlau
Journal of the Arkansas Academy of Science
The Brentwood Member of the Bloyd Formation conformably overlies the Prairie Grove Member, Hale Formation in the type Morrowan succession of northwestern Arkansas. At its type locality, the Brentwood is separated from the underlying Prairie Grove Member by nearly 6 m of dark shale. Away from this area, the shale thins rapidly and the Hale-Bloyd boundary may be placed with difficulty. At some localities east of type section, the boundary is thought to be erosional rather than the more typical gradational contact. The Brentwood consists of discrete carbonate bodies separated by dark shales. The carbonates consist principally of open shelf …
Mercury Content Of Waters In The Midcontinent Region, Larry Barber Ii, Kenneth F. Steele
Mercury Content Of Waters In The Midcontinent Region, Larry Barber Ii, Kenneth F. Steele
Journal of the Arkansas Academy of Science
Two major areas of the midcontinent region were investigated for their aqueous mercury concentrations. Sixteen surface water and 17 ground water samples were collected in an eleven county area of N.W. Arkansas, S.W. Missouri and N.E. Oklahoma (Ozark area) and analyzed for total dissolved mercury by the flameless atomic absorption spectrophotometric method. The range (<0.2 to 0.8 ppb), the mean (0.4 ppb) and the median (0.4 ppb) are the same for both ground water and surface water. Values obtained for the Ozark area are slightly greater than those reported for surface water by others (about 0.1 ppb), but are well within the range reported for surface waters (0.1 to 17.0 ppb). The range for 102 ground water samples from the Ouachita Mountain area is <0.1 to 2.3 ppb, the mean 0.3 ppb and the median 0.1 ppb. Thus, the mercury values for this area are similar to those of the Ozark area except fora higher upper range. The mercury mineralization (cinnabar) in the southern part of the Ouachita Mountain area, in part, is the cause of the higher values. Only two samples (2.1 and 2.3 ppb), both from the Ouachita Mountain area, exceed the EPA drinking water limits of 2 ppb mercury in the western Arkansas region.
Bibliography Of The Kentucky Geological Survey, 1839 Through 1978, Kentucky Geological Survey
Bibliography Of The Kentucky Geological Survey, 1839 Through 1978, Kentucky Geological Survey
Information Circular--KGS
It is the hope of the authors that all of the various publications and maps of the Kentucky Geological Survey are included in this bibliography. It is our intent to revise, supplement, and update the publication lists in "Geological Research in Kentucky" by Willard Rouse Jillson (1923).
During its history the Kentucky Geological Survey has suffered losses from two disastrous fires, one at Frankfort in 1929, and a second at Lexington in 1948. Many maps and some of the reports were reprinted after 1948 in Series VIII, but so many of the earlier publications were lost that they are now …
High-Carbonate And Low-Silica Stone In The High Bridge Group (Middle Ordovician), Fayette County, Central Kentucky, Garland R. Dever Jr.
High-Carbonate And Low-Silica Stone In The High Bridge Group (Middle Ordovician), Fayette County, Central Kentucky, Garland R. Dever Jr.
Information Circular--KGS
The High Bridge Group (Middle Ordovician) of central Kentucky, a major source of limestone and dolomite for construction and agricultural stone, is also a potential source of stone for industrial uses requiring carbonate rocks of high chemical purity. Chemical analyses of foot-by-foot samples from a Fayette County core show that several thick zones of high-carbonate and low-silica stone are present in the High Bridge at a minable depth.
The Geology Of The Southern Part Of The North Arm Mountain Massif, Bay Of Islands Ophiolite Complex, Western Newfoundland With Application To Ophiolite Obduction And The Genesis Of The Plutonic Portions Of Oceanic Crust And Upper Mantle, John F. Casey
Geology Theses and Dissertations
The Bay of Islands Ophiolite Complex forms a discontinuous belt of highly allochthonous mafic and ultramafic massifs in southwestern Newfoundland. The North Arm Mountain Massif contains the only significant exposures of sedimentary rocks overlying the ophiolite and also contains the most extensive exposures of plutonic rocks in the Bay of Islands Complex. Mapping has shown that sedimentary rocks, here named the Crabb Brook Group, rest with a pronounced erosional unconformity on ophiolitic rocks. Lithologic,paleontologic, facies, structural, and tectonic relationships indicate that this Group was deposited on the back of the ophiolite allochthon as it was being obducted onto the early …

The Geology Of The Northern Part Of North Arm Massif, Bay Of Islands Ophiolite Complex, Newfoundland: With Application To Upper Oceanic Crust Lithology, Structure, And Genesis, Eric J. Rosencrantz
Geology Theses and Dissertations
Detailed mapping (1:15,800) of the northern half of North Arm Massif shows the area to be underlain with a complete, although thin, ophiolite assemblage consisting, from top to base, of basalts, sheeted diabase dikes, isotropic and layered gabbroic rocks, layered ultramafic rocks and harzburgite tectonite. The assemblage represents a preserved piece of Cambrian oceanic crust analogous to present-day oceanic crust. Sheeted dikes and isotropic gabbros comprise the majority of the rocks exposed, with this sequence at present flat-lying to gently warped into open, upright but nonsystematic folds. Basalts occupy a shallow discontinuous N-S trending trough within the west-central part of …
Geology Of The Lewisporte/Loon Bay Area, Newfoundland, Canada, Richard F. Livaccari
Geology Of The Lewisporte/Loon Bay Area, Newfoundland, Canada, Richard F. Livaccari
Geology Theses and Dissertations
The Lewisporte/Loon Bay area is located within the Central Volcanic belt of Newfoundland. It contains rocks of (?)upper Cambrian to Ordovician in age. The most important group of rocks within this area is the three part Campbellton sequence. The oldest unit of the Campbellton sequence is the Loon Harbour Formation (500-1,000 m thick) composed of mafic volcaniclastics that is conformably overlain by manganiferous cherts of the Luscombe Formation. The Luscombe Formation (370 m thick) is composed of manganiferous cherts that grade upward into highly argillaceous chert. Conformably overlying the Luscombe Formation is the Riding Island greywacke that represents the uppermost …
Saratoga: The Bubbles Of Reputation And Their Implications For An Embryonic Rift System In The Upper Hudson River Valley, James R. Young
Saratoga: The Bubbles Of Reputation And Their Implications For An Embryonic Rift System In The Upper Hudson River Valley, James R. Young
Geology Theses and Dissertations
Carbonated, alkaline, saline waters occur over a wide area in the upper Hudson River Valley approaching 1,000 square miles. Through the sampling (spring and fall) of 39 locations, half of which were hitherto unsampled, the waters are shown to be a complexly mixed system with at least five major components.
They are:
1) a gaseous phase consisting primarily of CO2;
2) a fluid (containing the dissolved CO2) possibly analogous to a metamorphic brine whose major chemistry is HCO3>Na>Cl;
3) formational waters of variably low salinities which may be the end products of progressive dilution of Paleozoic connate brines …
Theoretical And Computer Assisted Studies In Tectonics, Structural Geology And Isotope Dating, Richard Leigh Thiessen
Theoretical And Computer Assisted Studies In Tectonics, Structural Geology And Isotope Dating, Richard Leigh Thiessen
Geology Theses and Dissertations
Several problems in the fields of tectonics, structural geology and isotopic dating were examined and simplified using computer programs. These problems include the theory of refolding, refold applications to three mining areas, hotspots and their relationship to mantle convection systems and ionium dating of volcanic rocks. In the first study, it was shown that current refold classification schemes are inadequate and so modifications were suggested. Various other aspects of multiple generations of interfering folds were also examined. The ideas of refold theory were then applied to three mining areas, the Chisel Lake Ore Body of Manitoba, the Galena-Roubaix District of …
Structural Geology Of The Fort Miller, Schuylerville And Portions Of The Schaghticoke 7½' Quadrangles, Eastern New York, And Its Implications In Taconic Geology; And Experimental And Theoretical Studies Of Solution Transfer In Deforming Heterogeneous Systems, William P. Bosworth
Geology Theses and Dissertations
Stratigraphies previously proposed for the Taconic sequence of southern Washington County, eastern New York, have incorrectly defined and positioned lower Cambrian black slate units. The proper sequence of Cambrian (?) through Cambrian lithologies is (terminology from Jacobi, 1977): Bomoseen green wacke, Truthville green slate, Browns Pond black slate, Mettawee purple and green slate, and West Castleton and Hatch Hill black slates. This and the entire Taconic sequence is conformable within the western Giddings Brook slice. The detailed lithostratigraphy reported by Jacobi (1977) and Rowley (1980) in northern Washington County can be followed at least some 45 kilometers to the south …
Complex Structure And Stratigraphy Of Lower Slices Of The Taconic Allochthon Near Middle Granville, New York, David B. Rowley
Complex Structure And Stratigraphy Of Lower Slices Of The Taconic Allochthon Near Middle Granville, New York, David B. Rowley
Geology Theses and Dissertations
The Precambrian (?) to medial Ordovician rocks of the Taconic Allochthon are characterized by argillaceous and arenaceous sediments with lesser associated carbonates, carbonate breccias, and cherts of predominantly deep-water aspect. These allochthonous rocks tectonically overlie an autochthonous to parautochthonous coeval sequence of dominantly shallow marine clastics and carbonates of the Champlain and Vermont Valley sequences. Facies, thickness, sedimentologic, and paleontologic considerations suggest that these coeval sequences represent a carbonate shelf continental rise pair of the east-facing early Paleozoic Atlantic-type margin of North America. This margin formed by the opening of an ocean in latest Precambrian time. The stratigraphy of the …

Preliminary Investigation Of The Ground-Water Resources Of Northern Searcy County, Arkansas, Wyndal M. Goodman, Albert E. Ogden
Preliminary Investigation Of The Ground-Water Resources Of Northern Searcy County, Arkansas, Wyndal M. Goodman, Albert E. Ogden
Journal of the Arkansas Academy of Science
Two aquifers are extensively used by residents of small communities and rural areas in northern Searcy County, Arkansas. The Mississippian Boone-St. Joe aquifer is generally the less productive and the shallower of the two. Ground-water yields for the Boone-St. Joe range from 0.5 to 75 gpm with a median yield of 5 and a mean of 9.8 gpm. Well depths range from 100 to 754 feet with a median depth of 350 feet and a mean of 360 feet. Confined conditions are indicated by the greater depths, whereas the Boone-St. Joe aquifer is unconfined when exposed at the surface. Underlying …

Geology Of The Columbia River Basalt In Silver Falls State Park, Oregon, Elizabeth Storm Norman
Geology Of The Columbia River Basalt In Silver Falls State Park, Oregon, Elizabeth Storm Norman
University Honors Theses
Silver Falls State Park is near the southern extent of the Columbia River Basalt Group as mapped in western Oregon. The flows in the park were identified as belonging to subdivisions of the Columbia River Basalt Group on the basis of physical characteristics and trace element geochemistry. The sequence of flows present is as follows: 3-4 flows of the Low-Mg chemical type of the Grande Ronde Basalt, 2 flows of the High-Mg chemical type of the Grande Ronde Basalt, 3 flows of the Frenchman Springs Member of the Wanapum Basalt, and one flow of anomolous geochemistry. The flows dip west …
