The Development Of Western Australian Sand Plain Soils For Agriculture, Richard Philip Roberts, F. L. Shier
The Development Of Western Australian Sand Plain Soils For Agriculture, Richard Philip Roberts, F. L. Shier
Journal of the Department of Agriculture, Western Australia, Series 4
IN a recently published economic survey of the Australian wheat growing industry, it was reported that nearly two-thirds of the farms surveyed in Western Australia were located on lateritic "sand plain."
As a random selection was made of the eighty farms that were visited it is reasonable to conclude that a similar proportion of all the State's wheat producing farms are on that type of country.
This constitutes a remarkable change from the earlier days of wheat belt settlement when the sand plain soils were regarded as virtually useless and by-passed for development.
It is the purpose of this article …
Cyclic Sedimentation Of The Upper Fayetteville Formation, Faramarz Frouzan
Cyclic Sedimentation Of The Upper Fayetteville Formation, Faramarz Frouzan
Masters Theses
"In the past decade considerable interest has developed in the geology of the Boston Mountain area of northern Arkansas. This has been due to exploration for oil and gas in-the area and the related desire to know more about the structure and stratigraphy of the region. Principal work has been done by the University of Arkansas, the United States Geological Survey, and oil companies. This study involves only one of the formations making up the geologic column in the Boston Mountains, the Upper Mississippian (Chesterian Series) Fayetteville Formation.
Portions of the upper part of the Fayetteville Formation of northwestern Arkansas …

Kimberley Research Station : A Progress Report, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
INTEREST in the agricultural potential of the Kimberley region in Western Australia dates from its early exploration and settlement in the last century.
Several farming development schemes were considered for the area, but were never implemented.
This could be mainly attributable to lack of knowledge of agricultural potentialities, limitations of the local environment and ways of exploiting the local environment.
Up to the present the economy of the region is almost entirely based upon the extensive production of beef and to a lesser extent, wool.
Soil Conservation In The Kimberley Area Of Western Australia, K Fitzgerald
Soil Conservation In The Kimberley Area Of Western Australia, K Fitzgerald
Journal of the Department of Agriculture, Western Australia, Series 4
OFFICERS of the Soil Conservation Branch of the West Australian Department of Agriculture, have not been engaged in soil conservation work in the Kimberleys prior to this year, not because a serious erosion problem did not exist, but rather because with limited trained staff available they were too fully occupied elsewhere.
The recent arrival of a senior Soil Conservation Officer in the area to assist and plan an approach to the problem of soil erosion in the Ord River catchment area is therefore very welcome.

Commercial Vegetable Growing In The Perth Metropolitan Region, L T. Jones
Commercial Vegetable Growing In The Perth Metropolitan Region, L T. Jones
Journal of the Department of Agriculture, Western Australia, Series 4
MARKET gardening with sprinkler irrigation on deep sandy soils around Perth is really a commercial application of hydroponics or sand culture principles.
Provision of a continuous and adequate supply of nitrogen is the major problem. Peat swamps scattered among the sandy areas have higher natural fertility. However, their common problems are drainage, acidity ("sourness"), salt and various special soil deficiencies. Over-liming of acid swamps can cause new problems.

Irrigation In Western Australia : Report On Government-Controlled Areas : 1958-59, H K. Gibsone
Journal of the Department of Agriculture, Western Australia, Series 4
IRRIGATION in the south-western portion of Western Australia is mainly confined to the coastal plain west of the Darling Range where the three main irrigation districts of Harvey, Collie and Waroona have been established by the State Government.
The Government-controlled irrigation areas extend southward from Waroona (70 miles from Perth) to Dardanup (120 miles from Perth) and have an average width of about five miles.
Pleistocene Geology Of Northern Kidder County, North Dakota, James Chmelik
Pleistocene Geology Of Northern Kidder County, North Dakota, James Chmelik
Theses and Dissertations
The topography of northern Kidder County is due almost entirely to glacial deposition. This are is covered with glacial drift up to a thickness of at least 269 feet which was deposited during Wisconsin ice advances. Seventy-five percent of the area has stagnation moraine which typically exhibits knob-and-kettle topography, has high local relief with no linear trends, and which was deposited after the ice became stagnant. Many kames and eskers were formed contemporaneously with stagnation moraine. The names, Lake Williams and Woodhouse Lake loops, and proposed for and moraines deposited by Cary and Mankato ice advances, respectively. The Lake Williams …
Glacial Geology Of South-Central Kidder County, North Dakota, Barrett J. Williams
Glacial Geology Of South-Central Kidder County, North Dakota, Barrett J. Williams
Theses and Dissertations
South-central Kidder County is covered with deposits of drift brought by ice sheets which invaded the areas from the northeast and east. Bedrock of Cretaceous age underlies the drift mantle. The drift on the surface in Kidder County represents the Cary and Mankato substages of the Wisconsin Stage of Pleistocene series.
Three types of moraines, ground, stagnation, and end moraine, are present in the area. Five late Wisconsin and moraines are distinguished and named in this portion of Kidder County. These are, from west to east and oldest to youngest, the Long Lake loop and Sibley Buttes loop of Cary …
Mississippian Bioherms Of Southwestern Missouri And Northwestern Arkansas, Arthur R. Troell Jr.
Mississippian Bioherms Of Southwestern Missouri And Northwestern Arkansas, Arthur R. Troell Jr.
Masters Theses
"Lenticular bodies of massive limestone, flanked by thin crinoidal beds, crop out in southwestern Missouri and northwestern Arkansas. They are within the St. Joe limestone of the Lower Mississippian.
Strata underlying these bodies typically are down-warped, those on the flanks lapping against, finally passing completely over the limestone core. Dips away from the “reef” are commonly around 5 degrees, but reach as much as 30 degrees. Conglomeratic detritus, originating from the core, occurs in flanking beds at their contact with it.
Thin sections of these masses show no more than 15 per cent of the limestone to consist of fossil …

Comparative Petrographic, Petrochemical And Spectrographic Analyses Of The Precambrian Granitic Rocks Of Southeastern Missouri, Eva B. Kisvarsanyi
Comparative Petrographic, Petrochemical And Spectrographic Analyses Of The Precambrian Granitic Rocks Of Southeastern Missouri, Eva B. Kisvarsanyi
Masters Theses
"Petrographic, petrochemical and spectrographic studies were completed on selected Precambrian granitic rock samples from Southeastern Missouri. This investigation contributes to a more detailed knowledge of the Precambrian granitic rocks of this part of the state.
Petrographic analysis of forty-four thin sections of granitic rocks from the St. Francois Mountains area revealed six different granite types. These have been named the Fredericktown, Knoblick, Doerun, Graniteville, Klondike and Silvermine granites. These rocks form a large part of a composite batholith. More than one period of granitic intrusion is represented, but differentiation also contributed to the formation of this diversity of the rocks. …
Occurrence Of Mineralized Ground Water In Southern St. Louis And Jefferson Counties, Missouri, Willard Glennon Owens
Occurrence Of Mineralized Ground Water In Southern St. Louis And Jefferson Counties, Missouri, Willard Glennon Owens
Masters Theses
"Mineralized ground water occurs at some localities in southeastern St. Louis and northern Jefferson counties, Missouri. This water is usually undesirable and is detrimental to development of ground water resources.
Water well records in the offices of the Missouri Geological Survey and Water Resources provided data for a study of structure, lithology and occurrence of ground water. Water well drillers and property owners were interviewed to obtain additional information concerning drilling problems and quality of water.
Geologic cross-sections, subsurface contour maps and isochlorinity maps aided the study of lithology, structure and areal distribution of mineralized ground water. Relationship is suggested …
Early History Of Malad Valley, Glade F. Howell
Early History Of Malad Valley, Glade F. Howell
Theses and Dissertations
The Malad Valley is geographically located in a unique position in the Pacific Northwest. The Bear River and its main affluent, the Malad River, are the only rivers in the Pacific Northwest that drain into the Great Basin, whereas the other streams and rivers of the states of Washington, Idaho, and Oregon empty eventually into the Pacific Ocean. It is also characterized for being the northern end of prehistoric Lake Bonneville, and eventually it was through this valley that an outlet opened to drain the lake. The soil deposits from this lake left a fertile valley, capable of producing most …
Stratigraphy Of The Winnipeg And Deadwood Formations In North Dakota, Clarence G. Carlson
Stratigraphy Of The Winnipeg And Deadwood Formations In North Dakota, Clarence G. Carlson
Theses and Dissertations
The Deadwood formation includes all of the pre-Winnipeg sedimentary rocks of North Dakota which range in thickness from an erosional edge in the subsurface of northeastern North Dakota to at least 1,000 feet in northwestern North Dakota. It is composed of sandstone, shale, and carbonate of Late Cambrian to Early Crdovician age. Facies relationships are not entirely clear, but sedimentation appears to have been continuous from Late Cambrian to Early Crdovician in the Williston Basin. Conodonts from the upper part of the Deadwood formation in northwestern North Dakota are brownish-black, mostly simple cone types and suggest an Early Drdovician age …
The Surficial Geology Of North-Central Kidder County, North Dakota, Wallace E. Bakken
The Surficial Geology Of North-Central Kidder County, North Dakota, Wallace E. Bakken
Theses and Dissertations
Kidder County is situated in central North Dakota within the glaciated Missouri Plateau. Rocks underlying the drift range from Cretaceous (Pierre formation) through Palocene (Tongue River formation) in age. The Pierre and Fox Hills formations constitute the majority of the pre-Pleistocene surface. Ice-shove deformation, apparently during Cary time, tilted blocks of Fox Hills in the Sibley Buttes into northeastward-dipping positions.
Cary and Mankato subages of Wisconsin age are represented at the surface. Ages are difficult to assign to drift sheets on the basis of lithology or degree of weathering of included tills; but by correlation from South Dakota and crosscutting …

Theses and Dissertations
Lower Mississippian rocks of the Williston Basin and Black Hills include the Bakken and Englewood formations of Kinderhockian age. The Englewood formation crops out in the northern Black Hills and can be traced with difficulty into the subsurface. The Bakken formation does not crop out in the area out in the area of this study. This study is based upon well sample and mechanical log information and measured surface sections.
The Englewood in the outcrops consists of a lower shale unit, a middle argillaceous and shaly limestone unit, and an upper delomitie limestone unit. A type section, NW, SE; see. …
Comprehensive Survey Of Sedimentation In Lake Mead, 1948-49, W. O. Smith, C. P. Vetter, G. B. Cummings, U.S. Bureau Of Reclamation
Comprehensive Survey Of Sedimentation In Lake Mead, 1948-49, W. O. Smith, C. P. Vetter, G. B. Cummings, U.S. Bureau Of Reclamation
Publications (WR)
Reservoirs are becoming an increasingly prominent feature of the American landscape. Built for flood mitigation and to change a fluctuating river into a dependable source of water for irrigation, power, and other purposes, they are predestined, like natural lakes, to be destroyed sometime following their creation. Sedimentation sooner or later robs most lakes and reservoirs of their capacity to store water. The significance of sedimentation in the life of Lake Mead, the largest artificial reservoir in the world, was realized when the plan for the reservoir was conceived, and an aerial survey of the floor was made in 1935 before …
Factors That Influenced Homesteading And Land Abandonment In San Juan County, Utah, Melvin J. Frost
Factors That Influenced Homesteading And Land Abandonment In San Juan County, Utah, Melvin J. Frost
Theses and Dissertations
Homesteading in San Juan County, Utah is for the most part, located on Sage Plain at elevations between 6,000 to 7,200 feet. Sage Plain is an undulating surface deeply dissected with canyons. The soil is relatively shallow and the predominant vegetation is pinyon, juniper, sage brush and blue-stem grass.
The 52 year mean precipitation is 15.47 inches. Since the beginning of weather records there has been a noticeable decrease in the annual precipitation. There is generally sufficient moisture to mature winter wheat. Pinto beans are also grown in the more favorable locations.
Principle factors that have influenced homesteading and land …

Opposed Discs For Furrowing In Pastoral Areas, W. M. Nunn
Opposed Discs For Furrowing In Pastoral Areas, W. M. Nunn
Journal of the Department of Agriculture, Western Australia, Series 3
THROUGHOUT our pastoral regions in all land divisions from Murchison to Kimberley, there are extensive areas of bare country which must be broken in some way to enable water penetration and to provide a place for seed to lodge before regeneration of pasture species can be expected. Earlier articles in this Journal have explained the occurrence of these bare areas, and described methods of furrowing. Checkerboard designs have been successful on perfectly level locations but contouring becomes essential where there is a slope of any dimension.
