Information of this nature will permit formulation of more accurate management practices because of a refinement in delineation of range sites.

Interbasin Movement Of Ground Water At The Nevada Test Site, Isaac J. Winograd

Publications (WR)

The present paper presents hydraulic evidence for the interbasin circulation of ground water through carbonate rocks of Paleozoic age at the Nevada Test Site. An integral part of this evidence is the discovery that aquifers in alluvium and tuff, formerly thought to be the principal aquifers at the Test Site, are semiperched above a thick tuffaceous aquiclude that separates them from the carbonate rocks.

This paper is based on one of the studies being made by the Geological
/="/">Survey for the Atomic Energy Commission. These studies seek to evaluate
/="/">the risk that may arise if ground water should …

Flooding And Salt Problems In The Wheatbelt, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

VALUABLE land has become salty in parts of the West Australian agricultural areas because most of the surrounding land has been cleared and developed for agriculture.

This salting of a small proportion of the land is part of the price paid for the development of agriculture in this State.

Drainage is not the answer to the wheatbelt flooding and salt land problems.

A more practical approach is to limit runoff from sloping land, and to make good use of salt-affected land by growing salt tolerant perennial pastures on it, says the Soils Division of the Department of Agriculture.

The Gascoyne River Catchment Area, W M. Nunn

Journal of the Department of Agriculture, Western Australia, Series 4

A RECENT Department of Agriculture survey of the Gascoyne River catchment area has indicated that deterioration of plant cover in the area contributes to the severity of floods which regularly damage the town of Carnarvon.

It is hoped that the results of the survey will help efforts to regenerate the catchment area, and reduce the risk of flooding.

Geology Of The Esterbrook Area, Converse And Albany Counties, Wyoming, Michael Nolan Greeley

Masters Theses

"The Esterbrook area lies within the Laramie Range in Converse and Albany Counties, Wyoming. Exposures include Precambrian metamorphic and igneous rocks, the Tertiary White River formation, and Quaternary alluvium.

Hornblende schist and mica-quartz schist comprise the Precambrian metamorphic rocks. Foliation planes of these rocks trend northeast and dip steeply to the southeast. Metamorphic rocks of younger age probably lie to the southeast.

A distinctive, Precambrian silicic pluton of biotite-leucogranite with marginal zones of muscovite-leucogranite and alaskite passively intrudes the metamorphic rocks, generally parallel to the foliation trends. Numerous granite pegmatites show a zonal distribution around the pluton and appear to …

Molybdenum Deficiency On Lighter Soils, Edgar Noel Fitzpatrick

Journal of the Department of Agriculture, Western Australia, Series 4

WIDESPREAD occurrences of molybdenum deficiency of subterranean clover have been observed on sandy and gfravelly surfaced soils in recent years, and present indications are that molybdenum will join copper and zinc as a major trace element deficiency of many of these soils.

Trace Elements For Cereal Crops And Pastures, Edgar Noel Fitzpatrick

Stilling Coastal Sand Drifts With Marram Grass, J L. Mcmullan

Journal of the Department of Agriculture, Western Australia, Series 4

DRIFTS in dunes on the coast between Albany and Geraldton may be stabilised by planting marram grass (Ammophila arenaria).

However, it should be anticipated that much of the planted grass will die before an area is finally stabilised.

Light Lands In Western Australia. 2. Their Nature, Distribution And Climate, George Henry Burvill

Journal of the Department of Agriculture, Western Australia, Series 4

LIGHT land development for agriculture is a major feature in the story of agriculture in Western Australia. Sixty years ago there was less than one million acres of arable land.

The total area planted to all crops was less than 250 thousand acres and the wheat harvest was less than one million bushels.

A Middle Miocene Rhinoceros Quarry In Morrill County, Nebraska (With Notes On Hip Disease In Diceratherium), Robert M. Stecher, C. Bertrand Schultz, Lloyd G. Tanner

Bulletin of the University of Nebraska State Museum (1924–2023)

Extensive deposits of fossil rhinoceros bones have been excavated from University of Nebraska State Museum collecting localities Mo-113, -114, -115, -116, and -118 some 8 1/2 to 9 1/2 miles north of Bridgeport, Morrill County, Nebraska. The fossils were associated with other faunal elements in the lower portion of the Marsland formation (middle Miocene) of the Hemingford group. The rhinoceros is considered to be Diceratherium niobrarensis Peterson, geologic variety. A pathologic right femur of D. niobrarensis provides evidence of hip disease in the medial Miocene rhinoceroses.

Early Records Of Some Mammals From Nebraska, J. Knox Jones Jr.

Bulletin of the University of Nebraska State Museum (1924–2023)

Ten species of Recent mammals that formerly occurred in Nebraska have been extirpated there by European man. Surprisingly few specimens of the species concerned are preserved in museum collections. Perusal of a representative segment of the historical literature pertaining to Nebraska has revealed records of occurrence of most of the extirpated species that provide a basis for estimating the former distribution of each in the State.

A Geologic And Gravity Survey Of The Belle Plaine Area, Minnesota, R. E. Sloan, Z. F. Danes

Journal of the Minnesota Academy of Science

Combined geologic and gravity investigations in the vicinity of Belle Plaine, in the Minnesota River valley, have disclosed a hitherto unknown fault of possible major significance. The fault is inferred on the basis of available evidence to have a left lateral displacement of the order of 100 miles and later vertical movements of about 1,000 feet. The field work was supported by the Minnesota Geological Survey. The writers wish to express their great appreciation to the late Dr. Edward Thiel of the Department of Geophysics and to Dr. J. C. Craddock and Barton Gross of the Department of Geology, University …

Farming Without Fallow, H M. Fisher

Journal of the Department of Agriculture, Western Australia, Series 4

UNDER the more intensive cropping rotations common in the early development of the cereal areas of Western Australia bare fallowing was a basic technique in cereal production.

By ploughing the land in July or August and keeping it bare of vegetation for nine or ten months, either by grazing or cultivation, a substantial beneficial effect on the subsequent crop could be expected.

Bare Patch And Poor Emergence Of Cereals. 3. Crusting Of The Soil Surface, S C. Chambers

Journal of the Department of Agriculture, Western Australia, Series 4

In some seasons extensive bare patches occur in cereal crops sown on the heavier wheat belt soils.

Experimental results from Beverley indicate that the poor emergence in some of these plantings may be due to crusting of the soil surface.

Working the surface with light harrows may destroy the crust and improve emergence.

Loss Of Structure In Wheatbelt Soils, T C. Stoneman

Journal of the Department of Agriculture, Western Australia, Series 4

MANY of the heavy soils of the West Australian wheatbelt have been farmed for 30 or 40 years, and farmers now frequently complain that these soils are becoming more difficult to handle, that greater power is needed to break up the soil, and the time that it remains in a workable condition after rains is shorter.

Seismic Investigation Of Flint Clay Deposits In East Central Missouri, Roland D. Dayley

Masters Theses

"Seismic refraction surveys were conducted in several localities within the east central Missouri clay districts in order to determine the applicability and economy of this method as a clay exploration tool. Results of these surveys revealed that the sink-type clay deposits possess lithologic and structural characteristics that lend themselves favorably to this method of exploration.

Seismic records obtained from profiles shot across known deposits indicate that several factors other than velocity contrast serve to produce apparent seismic anomalies.

Some unforeseen time loss and expense was encountered because of malfunctions of the seismic equipment employed, which necessitated the purchase and installation …

Light Lands In Western Australia. 1. History And Future Prospects, F L. Shier

Journal of the Department of Agriculture, Western Australia, Series 4

BECAUSE of the scattered distribution of light lands of the agricultural areas of Western Australia among the better soils, and their large total area, it is not surprising that attempts to develop these unattractive soils for agriculture started many years ago.

Ground Water Investigation In The Southern Half Of Franklin County, Missouri, Kemal Piskin

Masters Theses

"Increasing population and industrialization in Franklin County, Missouri, has led to increased demand for water. Much of this demand will be satisfied from ground water resources. Although the general geology of Franklin County has been mentioned in several publications, no detailed study of structure and ground water geology had been done. This thesis consists of study of stratigraphy, lithology, and geologic structure, and analysis of well log data to determine occurrence and availability of ground water, in the southern half of Franklin County.

Stratigraphy and lithology is compiled from previous literature, modified to agree with well log data. Structural geology …

Foraminifera Of The Cenozoic And Recent Genus Sphaerogypsina Galloway, Wayne C. Horton

Masters Theses

"The morphology of Sphaerogypsina as seen in thin section affords various characters useful in classification] 1) arrangement and composition of the wall (calcareous-perforate, radially crystalline); 2) layering of wall (like Gypsina, without layering or black line, having only microlamellae); 3) shape of test (always spherical); and 4) specific characters: size of test, order/unorder ratio, size of chambers, wall thickness, pore diameter, and type of embryonic apparatus.

Correlation of the above characters has allowed recognition of two new species. Comparisons with other genera strongly suggest placing the genus in the Family Gypsinidae (nom. correct.) rather than in the …

Application Of Digital Computer To Magnetic Data Interpretation Using Surface Integral Method, Afif Hani Saad

Masters Theses

"A simple method is developed for the calculation of the magnetic effect due to three-dimensional bodies. The method is based on the use of surface integration instead of volume integration. Thus, any three-dimensional body can be considered as having two surfaces, upper and lower, with magnetic pole distributions. Simple equations based on potential theory have been derived for the calculation of the vertical component and total intensity due to these surface distributions of poles. The anomalous field of the body can be obtained by subtracting the effect due to one of the surfaces from that of the other.

The method …

Syntheses And X-Ray Investigations Within The System Fes₂-Cos₂, Samuel Shu Mou Chan

Masters Theses

"Pyrite (FeS₂), cattierite (CoS₂), and various transitional members of the solid solution compounds were prepared. The methods used are as follows:

First, sulfides of cobalt, iron, or cobalt-iron were obtained by precipitation from a mixture of the cobalt chloride and/or ferrous sulfate in an aqueous solution. The dried precipitates were then mixed with an equal weight amount of sulfur and placed into silica glass tubes. After evacuation, they were filled with hydrogen gas of 3/4 of atmospheric pressure and sealed. The samples were then heated up to 500°C (for FeS₂), 650°C (for FeS_{2 …}

Study Of The Copper-Uranium Deposits At Vilcabamba, Department Of Cuzco, Peru, Oscar Aguilar

Masters Theses

"Uranium has been known in the Vilcabamba district of Cuzco, Peru since 1954. Copper ores of high silver content were worked by the Spaniards during the seventeenth and the early eighteenth centuries, At the beginning of the twentieth century these ores were worked intermittently; during the last fifty years no mining operation has been going on.

The oldest rocks in the thesis area consist of Ordovician phyllites. The presence of Devonian in the area is questionable, but has been recognized 5 km. away from the thesis area. A conglomerate of limited lateral extent of Mississippian age overlies the Devonian (?) …
