The Glacial Geology Of Eastern Sheridan County, North Dakota, Thomas C. Gustavson

Theses and Dissertations

During late Pleistocene time two ice advances affected parts of eastern Sheridan County, North Dakota. The first advance deposited the Burnstad, Streeter and Grace City drifts, and covered the whole county. The second advance deposited the Martin drift and occupied only the northern quarter of the county.

The Streeter drift, characterize by dead-ice landforms and nonintegrated drainage, is separated from the Burnstad drift by a large partly collapsed outwash plain on the distal side of a pronounced ground moraine and poorly integrated drainage, is separated from the Streeter drift by the Lincoln Valley and moraine and the Missouri Coteau escarpment. …

Structural And Magnetic Characteristics Of The Belton Anomaly, Cass County, Missouri, Nagib Chamon

Masters Theses

"A vertical intensity magnetic survey of approximately 156 square miles in Cass County, central-west Missouri, revealed a broad circular anomaly whose magnetic relief exceeds 1000 gammas. Surface rocks are very gently inclined and are of Pennsylvanian age. Crystalline basement rocks are at a depth of approximately 2400 feet. Analysis of the data shows that the Belton anomaly consists of discontinuous smaller magnetic anomalies surrounding the central part of this broad anomaly. The central area of the Belton anomaly is occupied by a magnetic low. Analytical calculation showed that the source of the magnetic disturbance is at least 3650 feet below …

Nature And Lateral Variation Of Lost Rock Limestone In The Tri-State Zinc-Lead District., Adnan A. Saadallah

Masters Theses

"The nature and lateral variation of a host rock limestone in the Tri-State zinc-lead district were petrographically studied within a single horizon, the M bed. This bed is a massive crinoidal limestone in the Tri- State district of southwestern Missouri, northeastern Oklahoma and southeastern Kansas and is a part of the Mississippian Keokuk Formation.

One hundred and twenty specimens from this bed were collected underground from six pull drifts in five mines: West Side, Grace B, Big John, Little Greenback, and Mudd Mines. The specimens were collected at regular intervals, usually ten to twenty feet, beginning at the edge of …

The Physical Limnology And Sedimentology Of Miller Lake, Martin River Glacier, South-Central Alaska, Edward Callender

Theses and Dissertations

Miller Lake is an ice-walled lake located on the terminus of the Martin River Glacier, south-central Alaska. It has an area of 1.36 km² and a mean depth of 25 meters. The lake basin was formed by the coalescence of several ice sinkholes and is characterized by extremely uneven bottom topography.

Analysis of detailed thermal data obtained during the summer of 1963 indicates that the lake is never permanently thermally stratified but does develop some stratification during periods of warm, calm weather. This stratification is easily destroyed by stormy weather. Miller Lake is classified as a subpolar lake due …

Type sections for all three members are herein established. Isopachous maps and stratigraphic cross sections have been prepared to delireate the thickness and distribution of each of the units …

Glacial Geology Of Western Wells County, North Dakota, George A. Faigle

Theses and Dissertations

The landforms of western Wells County were formed during late Wisconsinan glacial activity. Because of the relatively dry climate they have been modified only slightly by post-glacial erosion and mass wasting.

The southern one-third of the area is characterized by randomly-oriented mounds of till or dead-ice moraine. The dead-ice moraine originated when a large mass of stagnant ice ablated after typical glacial depositional features had formed on its drift-covered surface. Complete ablation of the ice resulted in the collapse of the previously formed features.

The remaining two-thirds of the area is characterized by and moraine, ground moraine, outwash, and meltwater …

Lower Paleozoic Chitinozoans And Scolecodents From North Dakota, Douglass H. Morgan

Theses and Dissertations

Chips from cores of the Red River and Stony Mountain Formations of Ordovician age and the Dawson Bay Formation of Devonian age in North Dakota were taken at three-foot intervals, dissolved in acid, and the residue examined for insoluble, pseudochitinous microfossils. Chitinozoa, an extinct order of rhizopod protozoans, were found in abundance along with lesser numbers of scolecodonts, the mouth parts of polychaete worms. Because the study was restricted to the core available at the North Dakota Geological Survey, which rarely included complete sections of the formations, a complete picture of the distribution of these forms must await the more …

The Geology Of Eastern Wells County, North Dakota, Ronald J. Kresl

Theses and Dissertations

Late Wisconsinan (Pleistocene) glaciation was responsible for the varied landforms of eastern Wells County. The Burnstad-Streeter phase advanced from the north-northeast about 10,000 to 12,000 years ago and was obstructed by the elevated Missouri Coteau which caused basal shearing and subsequent movement of subglacial drift into the ice. As this ice stagnated, the resultant drift cover impeded ablation and insulated the waters of superglacial lakes present on the surface of the Coteau at that time. Abundant Pleistocene fossils have been found in the sediments of these former lakes. Upon complete ablation, characteristic dead-ice features resulted on the surface of the …

Planning New Farm Dams : Excavated Earth Tanks, J E. Watson, J. C. Grasby

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

A GOOD farm dam is a valuable asset, and well worth its cost, but there are many aspects to consider when a new dam is required. Careful planning with adequate testing and checking will help to get the best value for money and reduce the chance of costly failures.

This article discusses these aspects in relation to the excavated earth tank type of dam.

Petrology And Mineralogy Of Certain Portions Of The Fredericktown Deposits, Farouk El Baz

Doctoral Dissertations

"The Fredericktown area is part of the 'Lead Belt' district of southeastern Missouri, the major lead-producing region in the world for fifty years. The district is a typical example of the Mississippi Valley Type deposits. The ores occur in Upper Cambrian sediments overlying Precambrian rocks.

The Fe-Cu-Pb-Zn (-Co-Ni) - sulphide deposits of Fredericktown occur over a few square kilometers in sediments overlying two 'granite knobs'. The sedimentary units lap upon and pinch-out against these buried basement hills.

The basal sedimentary unit, the Lamotte Formation, is a time-transgressive, marine, submature orthoquartzite. It contains a Boulder Bed at the base or at …

Algae And Their Mode Of Life In The Baradla Cave At Aggtelek Ii, George Claus

International Journal of Speleology

The author provides additional data to his publication of 1955. In a table he shows his results concerning 81 algal species which were returned to the cave of Aggtelek on June 22, 1954. When carrying out his control tests he found the decrease in the number of species to be 9 after 6 months and 18 after a further 8 months. In December 1957, after culturing on sun light however he was able to show again the presence of 17 species, but in his cultures Synechoccus elongatus, Phormidium dimorphum, Gloecoccus schròterii, Chlorococcum infusionum, Chlorella miniata and Protococcus anulatus, appeared …

The Microvegetation Of A Small Ice-Cave In Hungary, Erzsébet Kol

International Journal of Speleology

The algal flora of a small, artificial, ice-cave located in Northern Hungary is described. In this cave 23 species of algae (see in Table 3) were found of which the Cyanophyta and Chlorophyta occurred with approximately equal number. (9 vers. 11) It was found that the primary limiting factor influencing the penetration of the algae into the cave is the low temperature and not the lack of light.

Über Die Moose, Die Unter Dem Einfluβ Der Elektrischen Beleuchtung In Das Innere Der Höhlen In Ungarn Und In Der Tschechoslowakei Eindringen, A. Boros

International Journal of Speleology

The introduction of electrical illumination into different caves makes the intrusion of some mosses and ferns into such depths of the caves possible which at previous occasions (i. e. before the installation of electrical light) were found sterile of these plants. Investigations of two caves in Czechoslovakia and 4 caves in Hungary revealed the presence of mosses thriving deep inside of these caves making use of the artificial illumination.

Essai Sur Une Étude Au Microscope Électronique De La Microflore Des Sédiments Argileux De Cavernes (A Preliminary Study Using An Electron Microscope, On The Microflora Of Cave Clay Sediments), V. Caumartin

International Journal of Speleology

Researches on the microflora of cave clay sediments were carried out. The study of these micro-organisms necessitates the use of an enlargement of the order of 5,000. For this purpose the organisms were separated from the clay sediments by the foam flotation technique, followed by cultivation. Morphologically they can be divided into 5 types but together they form a group sufficiently homogeneous to justify their provisional grouping as the “Microfusiformetum.” Experiments with enriched cultures from several sediments have shown that certain of the micro-organisms were indigenous, others were accidental inhabitants.

Processes Of Limestone Cave Development, Alan D. Howard

International Journal of Speleology

Three processes successively predominate in enlarging original fractures within limestone into cavern passages: (1) early dissolving by acid produced by oxidizing reactions within the groundwater as it flows through the limestone; (2) dissolving caused by the initial undersaturation with respect to calcite of the groundwater when it enters the limestone; and (3) increased dissolving which occurs at the transition from laminar to turbulent groundwater flow. Only those original fractures in limestone which are widest and which have a high hydraulic gradient acting across them will be enlarged into cavern passages. Until all available surface drainage has been diverted underground, cavern …

Corrosion Par Mélange Des Eaux, Alfred Bogli

International Journal of Speleology

Karst caves are prior to all due to corrosion. According to the well-known formula a CO₂ supply is always needed. This type of dissolution explains only the corrosion in free circulation and, under reserve, the one in pressure conducts in the vadose zone. All corrosion in the phreatic domain is excluded, except for some rare cases in the upper levels. The corrosion by mixing of waters of different content in bicarbonates is effective in the entire karst, from the lowermost to the uppermost parts. Also the corrosion due to the lowering of temperature and by mixing of waters at …

Detection Of Caves By Gravimetry, Raymundo J. Chico

International Journal of Speleology

For gravimetric investigations, a naturally occurring limestone cave may be compared with a buried empty sphere or cylinder, depending on its shape. The practical limit of detection for a subsurface void, utilizing available equipment (Worden gravity meter) and standard field procedure, is 0.1 milligal. Most corrections normally required by the gravimetric method may be neglected in cave detection, but the altitude control for the field traverse must have an accuracy of ± 0.1 foot. The detectability of a limestone cave, based on field work done at Luray Caverns, Virginia, and at other localities, is related to its shape, Radius (R), …

Über Die Algenwelt Der Höhlen In Ungarn, P. Palik

International Journal of Speleology

An account of the researches carried out on the algae living in the caves of Hungary is given. The results of the investigations concerning the algal flora of the Baradla, Peace, Abaliget, Pàlvòlgy, Kòlyuk caves are enumerated. Theories about the possible energy source utilized by these algae living in the complete darkness of caves such as radiation, symbiosis, chemosynthesis or auxothrophy are discussed. The question of the settling of algae into the caves is debated.

Observations Sur L'Évolution Des Grottes, Albert Cavaillé

International Journal of Speleology

In this note, which results from a paper published in France, the author defines the “karst system” formed by several successive levels, at the heart of a limestone mass: joints of surface feeding, vertical chimneys, galleries which are alternatively dry and full of water according to the season, a network of continually drowned clefts. He then studies modifications in this system resulting from internal causes, corrosion, filling and sedimentation, concretion. Then he shows how this evolution of the karst system may be modified by general conditions: geology, tectonics, geography with the losses, resurgences and the role of surface formations. The …

Écologie De Fonticola Notadena De Beauchamp (Turbellarié, Triclade) Dans La Grotte De La Balme (Isère, France); Survie En Période De Sécheresse, René Ginet, Rodolphe Puglisi

International Journal of Speleology

During many months a year the acquatic Planaria (F. notadena) living in a small pool in the La Balme cave are subjected to a drought with the complete drying out of their biotope; they support in situ this lack of water and, living in a latent way inside the clayey matrix. Thanks to the great hygroscopy of the clay, enough humidity stays around the Planarians to enable them to survive. During this period the Planaria may undergo spontaneous divisions resulting in their asexual multiplication.
