Paleontology And Stratigraphy Of The Carboniferous Rocks Of The Placitas Region, Northern Sandia Mountains, Sandoval County, New Mexico, Donald Francis Toomey

Earth and Planetary Sciences ETDs

A paleontologic and lithologic study of the Carboniferous rocks of the northern Sandia Mountains demonstrates that this predominantly marine sequence is divisible into several important series which are recognizable elsewhere.

The pre-Pennsylvanian rocks lack diagnostic fossils. However, correlation with a fossiliferous sequence in the southern Nacimiento Mountains, based on similar lithology and stratigraphic position, indicates a middle mississippian Meramec age for these rocks. The thickness ranges from 21 to 81 feet; they consist mainly of limestone associated with basal elastics. This sequence lies directly on Pre-Cambrian rocks. Nine sections have been measured and are shown geographically on three plates.

The Soil Our Basic Asset, J E. Watson

Journal of the Department of Agriculture, Western Australia, Series 3

Contour furrows increase pasture growth

Good pastures on steep slopes will give profitable returns from grazing, and will also reduce erosion risks. Water needed for pasture growth on such slopes must not be allowed to run off and erode lower slopes. The use of contour furrows is a readily applied erosion control measure which can be very effective in increasing the amount of water held and absorbed on steep slopes.

Pre-North Horn Orogeny In Gunnison Plateau, Utah, Benjamin H. Burma, Clyde T. Hardy

Department of Earth and Atmospheric Sciences: Faculty Publications

This paper presents evidence for the post-Price River and pre-North Horn orogeny, in the Gunnison Plateau of central Utah (Fig. 1), and shows its magnitude. The first definite evidence of such a movement was found by C. T. Hardy in 1951, although it had been suggested previously, without definite evidence, by Gilliland (1949, 1951).

Oil Shales In Montana, Richard N. Miller

Bachelors Theses and Reports, 1928 - 1970

Montana has long been known to have very large resources of coal and oil, and undetermined amounts of oil shale. The reserves of coal and oil have been proven, in part, and have been produced commercially, but not much is known about the extent and apparent value of the oil shales. Under present .conditions, and according to standards set by the United States Bureau of Mines, the shales are not of commercial value. They are, however, a potentially valuable mineral resource, and portions of them will possibly be utilized, although not in the near future.

Stream Pollution, Ruth Patrick

United States Environmental Protection Agency: Publications

This paper discusses the various ways in which aquatic organisms may be of use in solving problems associated with waste disposal. Since many state and federal laws set forth that nothing may be discharged that is deleterious to aquatic life, the most expedient way to determine the effect of an effluent is to study the aquatic organisms themselves.

In every river that has not been adversely affected by pollution there is a great variety of aquatic life. These organisms do not represent a great mass of living things, but rather they are organized into an intricately balance systems, often referred …

Commercial Fertilizers For Winter Wheat In Relation To The Properties Of Nebraska Soils, R. A. Olson, H. F. Rhoades

Nebraska Agricultural Experiment Station: Historical Research Bulletins

It is the purpose of this bulletin to report the investigations that have been made correlating soil properties and fertilization practices with yields of winter wheat. Since the success or failure of fertilization practices is so dependent on specific soil conditions, an attempt has been made here to further characterize the major soils of the different sections of the state which are devoted to wheat production and to analyze fertilizer practices and results in relation to the soil properties determined. The data are summarized for the four sections of the state designated as southeastern, east-south-central, west-south-central and western Nebraska. These …

On The Theory Of Head Waves, Patrick Heelan

Research Resources

When a combined longitudinal and transverse disturbance, diverging from a localized source, strikes a plane boundary between two solid elastic media, several systems of head waves and second order boundary waves are generated, each associated with grazing incidence of one or the other of the reflected or refracted waves. Associated with grazing incidence of P ₁ P₂, the refracted P-wave, is the head wave system comprising P₁P₂P₁ (the "refracted wave" of seismic prospectors), and P₁P₂S₁ (a transverse head wave) in the upper medium, and P₁P_{2 …}

A Geomagnetic Survey Of Parts Of Pierce, Benson, Sheridan And Wells Counties, Harald C. Haraldson

Theses and Dissertations

A magnetometer survey in respect to oil exploration is a regional reconnaissance tool and, therefore, it is customary to check an interesting magnetic anomaly with a seismograph or gravimeter. An exception to this is found in micro magnetic surveys which, because of their detailed nature 28 nature, may serve as a cheek on the other types of geophysical surveying.

The two large magnetic highs may be more areas in the basement rocks, and they may indicate structure. However, the large eastward-trending magnetic high area on the west side of the map area is quite possibly due to a regional increase …

A Study Of Immiscibility In The Carbonates From The Metamorphic Rocks Of Southeastern Vermont, Ralph D. Cotter

Masters Theses

"This problem is an attempt to correlate grade of metamorphism (normally assumed to be temperature dependent) with the shape and dimensions of a solid miscibility gap. Such a correlation might permit mapping of a continuously variable function of metamorphism. The system, calcite and dolomite-ankerite, was chosen for study because of its relative simplicity. Samples of quartz-carbonate granulite were collected from the Waits River formation in southeastern Vermont through a range of metamorphic grades. Refractive index, "molecular" volume, manganese content, and density were determined for the carbonates of four of these samples. These values are plotted on a compositional diagram to …

A Petrographic And Chemical Study Of The Bevier Coal Seam, Philip John Clarke

Masters Theses

"Samples of coal were taken at three inch intervals vertically down the Bevier seam at three localities in Macon and Randolph Counties. Channel samples were collected at the three localities. All samples were analyzed for ash content, total sulphur content, crucible swelling number, and volatile content. The channel samples were analyzed for "pyritic" sulphur, “sulphate" sulphur, and "organic" sulphur. Thin sections of the samples were used in an estimation of anthraxylon and attritus contents.

In all the samples studied, volatile content of the coal seemed to be related to the ash content and the sulphur content. Crucible swelling number also …

Wind Erosion Control—I, D J. Fleay

Journal of the Department of Agriculture, Western Australia, Series 3

Desserts have been formed in some parts of the world by the action of wind on once productive soils. This could happen to the light land areas of Western Australia if we do not profit by the lessons of the past and manage these soils with great care.

The Regeneration And Maintenance Of Wimmera Ryegrass Pastures Under Saline Soil Condition, F L. Shier

Journal of the Department of Agriculture, Western Australia, Series 3

Over the past ten years, Wimmera ryegrass pastures at the Salmon Gums Re- VJ search Station have been improved and maintained by periodic cultivation of the soil even without applications of superphosphate. On heavy crab-holey soil affected by high salt content and unsatisfactory for wheat growing, cultivation treatments have produced remarkably uniform stands of Wimmera ryegrass as shown in the accompanying pictures. The bare patches due to salt, have been largely eliminated. If the interval between cultivations is more than three years Wimmera pastures deteriorate badly.

Soil Conservation Service - Basis Of Co-Operation, G H. Burvill

Journal of the Department of Agriculture, Western Australia, Series 3

The Soil Conservation Service has been established as provided in the Soil Conservation Act, 1945. To carry out its objectives will require the co-operation with it of individual farmers and landholders. The policy of the Service is therefore to encourage farmers to help themselves, and particularly to encourage them to recognise the need for soil conservation methods and for soil erosion control in the early stages. More particularly, the Service aims to provide, through its trained staff, technical asistance in the way of agricultural advice, research, conservation, planning, layouts and surveys. As indicated below, under the heading "Charges for Soil …

Pleistocene Evolution Of The Ohio And Wabash Valleys, William J. Wayne

Department of Earth and Atmospheric Sciences: Faculty Publications

Studies of drift thickness and character currently in progress in Indiana indicate changes in drainage that have occurred in Indiana and some adjoining states since the beginning of the Pleistocene epoch. After late Tertiary (Lexington) peneplanation the master-drainage line, the Mahomet-Teays Valley system, became entrenched about 200 feet below its former level before it was ponded by Nebraskan ice and diverted into a new course. During the Parker cycle, which was interrupted by glaciation, the present physiographic features of southern Indiana and their now buried extensions to the north became recognizable. Static rejuvenation then was a major factor in erosion …

Soil-Saving Schools

Journal of the Department of Agriculture, Western Australia, Series 3

Save the soil for your sons and grandsons," or "Every farmer his own soil conservationist" might well serve as slogans for the recently-inaugurated farmers' schools organised in this State by the Soil Conservation Service. Judging by the enthusiasm shown by pupils at the first two schools, held in August last, this highly practical approach to an important subject seems destined to usher in an entirely new conception of soil conservation work as it affects the individual land-owner.
