UMR Journal -- V. H. McNutt Colloquium Series

The distinguished authors of these tectonic studies, which span the United States from the Atlantic continental shelf margin to the Pacific coast, need no introduction to the geologic profession. Each was selected as a participant in the V. H. McNutt-Geology Department Colloquium because of his intimate knowledge and thorough research on the tectonic development of the area on which he reports. The authors publicly presented their papers during the Spring of 1966 on the campus of the University of Missouri at Rolla (formerly University of Missouri School of Mines and Metallurgy). The colloquium volume is unique in that such a …

Tectonic History Of Midcontinental United States, Frank G. Snyder

UMR Journal -- V. H. McNutt Colloquium Series

Metasediments of Middle Precambrian, and possibly some of earlier age, form an arcuate trending belt across Missouri, Kansas, and Nebraska. These were intruded by granites of several ages that appear to be part of a continuous wave of Late Precambrfan igneous activity. Late Precambrian events that can be delineated include, besides the igneous activity and formation of iron deposits, development of a Keweenawan basin that extended from Lake Superior into eastern Kansas; igneous activity and metamorphism of Grenville age in the eastern Midcontinent; development of a major fault lineament extending northeastward from northeast Arkansas into the Canadian shield outcrop area …

The California Coast Ranges, John C. Crowell

UMR Journal -- V. H. McNutt Colloquium Series

Western California between the 37th and 40th parallels is part of an active mobile orogenic belt in which sedimentation, deformation, volcanism, and plutonism have been intimately associated since the mid-Mesozoic. At present, the region is still undergoing folding and warping as shown by data from geodetic triangulation networks and geomorphology, and several major high-angle fault zones are seismically active. These faults continue to acquire displacement both suddenly during earthquakes and slowly by gentle creep with no recordable shocks. Pleistocene beds and terraces at places are steeply warped. Strong deformation occurred during the late Pliocene and early Pleistocene. Most of the …

Bulletin No 3547 - Kimberley Research Station - Progress Report 1968, Western Australian Department Of Agriculture

Bulletins - 3000 - 3999

Rivers flowing to the Gulf of Carpentaria and the Timor Sea have been estimated by hydrologists to carry about three times the water transported annually over the Murray drainage system and the South Eastern slopes which, together, comprise the highly settled agricultural areas of South Eastern Australia.

In 1945, the North Australian Development Committee recommended research in the Ord-Victoria rivers region as a first step toward ultimate agricultural development of this Northern potential and, in 1946, the Kim- berley Research Station commenced operations under the joint control of the Commonwealth Scientific and Industrial Research Organization and the Western Australian Department …

The Effects Of Geographical And Climatic Setting On The Economic Advantages Of Alternative Flood Control Measures, Clyde R. Dempsey, L. Douglas James

KWRRI Research Reports

It has long been realized that tributary urban development and channel improvement greatly affect the flow regime in a given watershed. A previous study used the Stanford Watershed Model to derive relationships expressing how the flood peaks in Sacramento, California, might be expected to vary with changing conditions of urbanization, channelization, and tributary drainage area. In order to observe the effects of climatic setting and geographical location on these relationships, the same type of analysis was applied to a drainage area near Louisville, Kentucky.

If reservoir storage is to be considered in a flood control program, it is necessary to …

Procedure And Structure For An Instructional Laboratory Which Supplements Research, R. S. Adams Jr.

Journal of the Minnesota Academy of Science

This paper describes the organization of a laboratory course in Soil Chemical Analysis. Students select and pursue small research problems to gain experience in the soil analyses that are discussed in lecture and required in the laboratory. Involvement of the class in an actual research problem proved challenging to both the instructor and the class. The data obtained often supplemented current departmental research. Individual projects were found to be easier to supervise than team problems. This paper reports results of a team project examining parameters of a pot experiment. Shape of the pot, methods of watering, methods of fertilizing, and …

Multiple Cropping Will Increase The Erosion Hazard, W J. Burdass

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

WITH the low price of wool and the price of wheat high in comparison, farmers need little encouragement to increase their acreage of crops.

Unfortunately with increased cropping comes the risk of increased erosion—unless there is a simultaneous increase in the use of conservation practices.

Mineralization Of The Boss Bixby Anomaly, Iron And Dent Counties, Missouri, Frederick Joseph Smith

Masters Theses

"The Boss-Bixby deposit is located on the line dividing Iron and Dent Counties and belongs to the Southeast Missouri Precambrian Iron Metallogenic Province. The sequence of events leading to the formation of the deposit is reviewed. The mineralization occurred after intrusion of intermediate magma, but prior to the intrusion of granite. The ore minerals present are the following in the order of deposition: magnetite, ilmenite, giekielite, hematite, rutile, pyrite, molybdenite, cobaltite, chalcopyrite, bornite, sphalerite, galena, limonite, chalcocite, and cuprite. Four different methods of zoning are presented. Partial pressures of oxygen and sulphur [sic], as well as temperature controlled sequential deposition …

On A New Species Of Earthworm From A Mexican Cave, Gordon Gates

International Journal of Speleology

Eodrilus mexicanus of the megadrile oligochaete family Acanthodrilidae is described along with some data as to development, regeneration and abnormality. Relationships with its American congeners, often inadequately characterized, are discussed and the present state of Eodrilus systematics is criticised. E. mexicanus seems likely to be of unusual interest as the second species of earthworm to have ovaries in segment xii.

Magnetic After-Effects In Dilute Transition Metal Alloys, Robert Henry Graham

Masters Theses

"Temperature dependent after-effects of the initial permeability in ternary dilute ferromagnetic iron-base alloys were studied in the temperature range of -50°C to +30°C. Interstitial carbon and nitrogen were the diffusing elements. Nominal percentages of the substitutional transition elements manganese, chromium, vanadium and titanium were added to determine the extent of substitutional-interstitial pair interactions. No additional temperature dependent after-effect of the initial permeability was noticed in Fe- substitutional -C alloys, while such after-effects were present in Fe- substitutional -N alloys. Magnetic after-effect data were analyzed on the basis of single Debye relaxations. Relaxation times for carbon and nitrogen diffusion in alpha-iron …

Sulfide Mineralogy And Fabrics Of The Iron Ores At Benson Mines, New York, Pedro Hugo TumialáN De La Cruz

Masters Theses

"The occurrence of sulfide minerals and their textural relationships to the silicate and oxide minerals in the Benson Mines, New York, iron deposit were investigated by ore microscopic and petrographic means. The Benson deposit is one in which the dominant iron oxides, magnetite and hematite, occur in a quartz-feldspar gneiss which was subjected to hornblende granulite subfacies metamorphism. Two hundred ore and country rock specimens were systematically collected from all parts of the open pit mine. Polished sections and thin sections were prepared from nearly all of the collected specimens. The oxide ore exhibits a granular texture in which isolated …

Design And Testing Of A Downhole Continuous Wave Generator, Cole L. Smith

Masters Theses

"The continuous shear wave generator was designed to be the first instrument capable of producing a continuous high frequency signal below the weathered layer of the earth. This is to be accomplished by placing the instrument in a bore hole and lowering it below the weathered layer where the higher frequencies are severely attenuated. The generator produced a measurable signal output with the output force being approximately 11 pounds force. Testing of the generator showed the necessity of using a spring system with a low natural frequency. The testing also indicated several improvements which should be made in the generator …

The Geology Of The Thayer Area Emphasizing The Stratigraphy Of The Cotter And The Jefferson City Formations, William Jesse Hedden

Masters Theses

"Detailed geologic mapping of the Cotter-Jefferson City formational contact in the Thayer, Missouri area demonstrates the feasibility of using this contact. This mapping also delineates significant faulting in the area.

The stratigraphy of the Cotter and Jefferson City formations in the Thayer area has been studied to find a mappable contact between the two formations. The contact was mapped in this area by using marker beds, the stratigraphic positions of which were determined by applying insoluble residue techniques to outcrop sections. Because the insoluble residue zones of the Cotter and Jefferson City formations are recognizable throughout the state of Missouri …

Lateral Variations Of Carbonate Rock Adjacent To Ore Deposits In The Upper Mississippi Valley Zinc-Lead District, Wisconsin, Illinois, Iowa, Mehdi H. Mirbaba

Masters Theses

"The lateral variation and nature of carbonate host rock in the Upper Mississippi Valley zinc-lead district were petrographically studied within the McGregor and Quimbys Mill Members of the Platteville Formation of the Middle Ordovician System. These members are dolomitic limestone in the Upper Mississippi Valley district of southwestern Wisconsin, northwestern Illinois and northeastern Iowa. One hundred and twenty-seven specimens were collected or were available from pull drifts in the Shullsburg mine. The specimens were collected at regular intervals of 50 or lOO feet in seven pull drifts between eight ore bodies. Thin sections prepared from the carbonate specimens were studied, …
