The Uranium-Trend Dating Method: Principles And Application For Southern California Marine Terrace Deposits, Daniel R. Muhs, John N. Rosholt, Charles L. Bush

United States Geological Survey: Staff Publications

Uranium-trend dating is an open-system method for age estimation of Quaternary sediments, using disequilibrium in the ²³⁸U–²³⁴U–²³⁰Th decay series. The technique has been applied to alluvium, colluvium, loess, till, and marine sediments, in this study we tested the U-trend dating method on calcareous marine terrace deposits from the Palos Verdes Hills and San Nicolas Island, California. Independent age estimates indicate that terraces in these areas range from –80 ka to greater than 1.0 Ma. Two low terraces on San Nicolas Island yielded U-trend plots that have a clustered array of points and the ages of …

Stratigraphy, Diagenesis, And Depositional Environment Of The Cowlitz Formation (Eocene), Northwest Oregon, Leonard Carl Farr Jr.

Dissertations and Theses

The Upper Eocene Cowlitz Formation is exposed in surface outcrops southwest of the town of Vernonia, in Columbia County, Oregon. The Cowlitz Formation also occurs in the subsurface of the Mist gas field where its Clark and Wilson (C and W) sandstone member (informal) acts as a natural gas reservoir, and its upper Cowlitz mudstone member (informal) acts as a cap rock. Surface exposures and continuous core were studied in order to determine Cowlitz Formation stratigraphy, and its depositional environment. Fresh core samples were also studied petrographically, and with a scanning electron microscope, in order to determine the effects of …

Caratteri Generali Delle Morfologie Nelle Alpi E Prealpi Giulie E Nel Carso Triestino, Franco Vaia

International Journal of Speleology

The morphology of the Julian Alps and Prealps and of the Triestian Karst are here shortly described; the structures, which defined its origin and development, are also considered. We can notice some cliffs which follow one another from the State boundary to the Adriatic sea; they are made up by lithologic successions, which repeat themselves according to the latitude. Anyway we recognize a general outcropping of rock masses which are decreasing little by little southward as regards the altitude, the age and than the erodibility. There are some differences between the western (Carnian) and the eastern (Julian) bend of the …

The Hydrogeology Of A Landfill Located In Fine-Grained Lacustrine Sediments In A Saline Discharge Area West Of Grand Forks, North Dakota, John T. B. Betcher

Theses and Dissertations

The Grand Forks Municipal Landfill, located in the Red River Valley of eastern North Dakota, accepts household refuse from the city of Grand Forks and from surrounding rural communities including several towns in northwestern Minnesota. The landfill occupies 160 acres (64.8 hectars) and another 160 acres (64.8 hectars) is available for expansion. The trench method of disposal is used at the landfill.

A geologic and hydrogeologic investigation was undertaken at the landfill to determine the characteristics of the shallow, saturated, fine-grained lacustrine sediments for solid waste disposal. Test holes were drilled to collect core samples for textural analysis, clay mineralogy …

Quaternary Alluvial Sequence Of The Upper Pecos River And A Tributary, Glorieta Creek, North-Central New Mexico, Paul Arthur Karas

Earth and Planetary Sciences ETDs

Quaternary alluvial deposits preserved on terraces along the Pecos River and a tributary, Glorieta Creek, provide a record of the evolution of these two drainages. Alluvium deposited by the Pecos River can be subdivided into six units on the basis of relative topographic position and degree of soil development on original surfaces. Deposits consist of thin (1 to 10m) veneers on scattered strath terrace remnants. Only four Quaternary alluvial units have been identified along Glorieta Creek. Alluvium deposited by this stream forms nearly continuous fill terraces of thickness equal to or greater than the Pecos River alluvium. Alluvial deposits of …

The Soils Of The Salmon Gums District, Western Australia, George Henry Burvill

Technical Bulletins

Most of the soils are grey and brown solonized soils. The subsoils, to about 2 m, are calcareous sandy clays with limestone rubble, but there are three main surface variations: sandy surfaced, 5-30 cm deep, passing abruptly to the sandy clay subsoil with lime nodules. The Circle Valley sand and Scaddan sand are major types. Scaddan sand has a domed subsoil clay. Powdery calcareous sandy loam; and clay loam and clay with some lime in the subsoil, but less than in 1 and 2.

Safe Disposal Of Pesticide Containers And Residue, Doug Johnson, Monroe Rasnake, James Martin

Soil Science News and Views

The use of pesticides (herbicides, insecticides, fungicides, etc.) has been an important factor in improving productivity of American agriculture to the point that quantity and quality of food and fiber produced by American farmers is unequalled in the world. However, in recent years, increased concern is being expressed regarding potential harmful effects of pesticide use on the environment. Most farmers want to know how to safely handle pesticides and dispose of waste materials, and the pesticide industry is working hard to develop better systems for handling pesticides. However, poor disposal practices are still too common.

A Seismic Analysis Of Reefs In The Traverse Limestone Of Allegan County, Michigan, William Charles Henderson

Masters Theses

A seismic reflection study was performed across the Diamond Springs oil field in Allegan County, Michigan. The horizon of interest was the Middle Devonian Traverse Limestone located 1,700 feet in the subsurface. Within the Traverse Limestone are scattered patch reefs which characterize a targeted reservoir. The use of high-resolution, shallow seismic reflection techniques are useful for defining detailed subsurface porosity zones within the patch reef reservoirs.

Common source-offset profiling utilizing high-frequency sources and proper determination of field parameters are important in obtaining the desired optimum reflection. Also, the use of synthetic seismograms for modeling waveforms is essential for identifying the …

Geometry And Kinematics Of The Central Snowcrest Range: A Rocky Mountain Forehand Uplift In Southwestern Montana, Barry Christopher Mcbride

Masters Theses

The Snowcrest Range forms the southeastern limb of the Late Cretaceous Blacktail-Snowcrest uplift. The northeast-trending uplift is bounded by the northwest-dipping Snowcrast-Greenhom thrust system which consists of seven thrust zones which merge and flatten at depth along a regional detachment horizon within the Archean basement.

The structures forming the Snowcrest Range are concave westward with trends varying from N 55° E in the southern region to north-south in the northern region. Calcite twin lamellae and fracture orientations indicate that the principal shortening direction was oriented S 85° E during late Cretaceous time. This orientation requires that a significant component of …

Variation In Sulfur Dioxide Emissions Related To Earth Tides, Halemaumau Crater, Kilauea Volcano, Hawaii, Charles B. Connor, Richard E. Stoiber, Lawrence L. Malinconico Jr.

School of Geosciences Faculty and Staff Publications

Variation in SO₂ emissions from Halemaumau crater, Kilauea volcano, Hawaii is analyzed using a set of techniques known as exploratory data analysis. SO₂ flux was monitored using a correlation spectrometer. A total of 302 measurements were made on 73 days over a 90‐day period. The mean flux was 171 t/d with a standard deviation of 52 t/d. A significant increase in flux occurs during increased seismic activity beneath the caldera. SO₂ flux prior to the this change varies in a systematic way and may be related to variation in the tidal modulation envelope.
