• Laboratory Performance of Wicking Fabric H2Ri in Silty Gravel, Sand and Organic Silt

      Connor, Billy; Zhang, Xiong (16-05)
      The use of wicking fabric, H2Ri, is growing in its use to remove water from roadway and airport embankments. Past research has shown H2Ri to be effective in sands and fine grained materials in roadways up to 32 feet in width. However, there is a desire to use H2Ri for airports which require a minimum width of 75 ft. This project tested H2Ri in a 73-foot flume in a crushed surface course with 14 % fines. In addition, the fabric was tested in a 22-foot flume with a sand and with an organic clay. The intent was to bracket the material for which the H2Ri will work. The study showed that the fabric will easily move water 73 feet in a silty gravel. The study showed that the fabric was also able to readily remove water in sand. However, the fabric blinded when used in organic silt and proved ineffective. The study also showed that using simple overlap of the H2Ri as a splice, while effective, was not as efficient at moving water as the fabric itself. Consequently, moisture tended to build up around the splice.
    • Magnetometer and direct-current resistivity studies in Alaska

      Joesting, Henry R. (University of Alaska Mineral Industry Research Laboratory, 1941)
      During the past year and a half, the territorial Department of Mines in Alaska has conducted a modest experimental program for the purpose of determining the extent to which magnetic and resistivity methods can be used in interior Alaska in connection with prospecting, mining and geological studies. Since little information is available concerning previous work, and since conditions differ considerably from those in most other regions, it was considered advisable to make a general study of the possibilities and limitation[s] of the two methods, rather than a detailed study of any single problem.
    • Annual report of research progress

      MIRL (1964)
      Research that will lead to the utilization of Alaska's mineral resources and hence create new wealth must be 1::ontinued at an increased rate in the future if a strong mineral industry is to be developed and maintained. Current investment in minerals research is a judicious practice that will pay dividends to the State in the future. The Engineering Council for Professional Development, in their 1964 report which continued the accreditation of the engineering curri1:: ula at the University of Alaska, emphasized this concept when they stated: ''Regardless of the mining industry's present size, the State clearly needs a mining center in its State University not only for teachi} 1g but also for research and for service to prDspectors and mine operators." The Mineral Industry Research Laboratory is dedicated to those objectives of research, instruction and service which will help build the mineral economy of Alaska.

    • Annual report of research progress

      MIRL (University of Alaska Mineral Industry Research Laboratory, 1965)
      Continuous research is the key to problem solutions and also to new developments in winning minerals from any environment, be it the land, the air, or the sea. Strong research programs yield both present and future benefits and are part of any vigorous, dynamic development. In Alaska, new mineral deposits must be searched for; marginal and submarginal deposits must be reviewed in terms of sophisticated methods of mining, benefication and extraction; and greater utilization must be developed for Alaska's industrial minerals, fuels, and off-shore mineral deposits. Continuous research, directed toward solving problems of present mineral production and uses, yields a technology which will solve future problems, and is essential if a vigorous mineral industry is to continue to play its basic role in Alaska's growing economy. Since mineral resources are of limited value without human resources, the Mineral Industry Research Laboratory is also dedicated to the development of Alaska's young men and women for careers in the mineral industry.

    • Petrographic evaluation of coking potential of selected coals and blends

      Harkinson, F.C. (University of Alaska Mineral Industry Research Laboratory, 1965)
      The United States Bureau of Mines, Geological Survey, and other agencies have made extensive investigations on Alaskan coals. Coke tests on Alaskan coals as early as 1908 have indicatedd, that a few coals are of coking quality. However, lack of known coking coal reserves large enough for economic exploitation precludes competitive marketing. These coals which do indicate coking quality often occur in isolated areas and in complex geologic structure, thus prohibiting development. This study by no means defines the economic feasibility of mining, processing, or marketing of potential coking coals, but rather is concerned with new innovations of coal science to determine the possibility of blending coking cads with non-coking coals. Results i n d a t e that coherent coke products may be made by this blending and further illustrates a possible increase in reserves of coking coal.
    • The market potential for Alaskan clay products

      Beasley, C.A. (University of Alaska Mineral Industry Research Laboratory (MIRL), 1965)
      This study was originally proposed to the Alaska Department of Economic Development and Planning as part of a continuing effort by the Mineral Industry Research Lab of the University of Alaska to strengthen and diversity the mineral industry of the state.
    • The market for insulation in Alaska and feasibility of the regional manufacture of insulating materials

      Haring, R.C.; Beasley, C.A. (University of Alaska Mineral Industry Research Laboratory, 1965)
      This investigation was undertaken jointly by the Mineral Industry Research Laboratory and the Institute of Business, Economic and Government Research at the University of Alaska. It is one of a continuing series of studies concerning the market and utilization rate for selected structural materials within Alaska. The overall objective of these studies is to identify opportunities for the regional manufacture of selected building products. In this manner, this limited study of insulation markets complements more extensive previous studies concerning Alaskan cement and clay products, markets and manufacturing feasibility.

      The mineral and human resources of a state and/or nation are to a large extent the basis of a strong and flourishing economy. In Alaska this is currently illustrated by the activities of the oil and gas industry and the resulting large sums of money that have gone into the state Treasury to help give a sound financial basis to Alaska. The Mineral Industry Research Laboratory has concentrated its efforts on research that will help in the more complete utilization of Alaska's mineral resources for work in the state's mineral industry. This report describes in moderate detail the projects that have been undertaken. These are in the areas of mineral economics, exploration, mining, mineral benefication, beach and ocean mining, utilization of nonmetallics, use of coal resources, and the solving of numerous' specific problems posed by mining people of the state. Training of young men and women for the mineral industry is stimulated by their having the opportunity to work on projects as a part of their graduate program under the supervision of the staff of MIRL. Theses completed offer a considerable amount of information to the public. Recent completed theses are listed in this report. The laboratory has been supported financially by the state of Alaska and various grants and work in kind from individuals and agencies. Private industry has helped in purchasing equipment and cooperative projects are underway with government agencies. Personnel and facilities of the College of Earth Sciences and Mineral Industry supplemented by other professional personnel are involved in teaching and research as set forth in enabling legislation for the Laboratory.

    • Geochemical-geophysical investigations, Fairbanks district

      Heiner, L.E.; Beistline, E.H.; Moody, D.W.; Thomas, B.I.; Wallis, J.E.; Loperfido, J.C.; Peterson, R.J.; Wolff, E.N. (University of Alaska Mineral Industry Research Laboratory, 1967)
      Trace element distribution in a subarctic valley in the Cleary Hill area of the Fairbanks gold district has been studied. Zinc and arsenic have been found excellent pathfinder elements for auriferous deposits. Methods of analysis for copper, lead, zinc, molybdenum, silver and arsenic as well as heavy metals are discussed. The University of Alaska method #2 has been improved, Terrain, slope, and frozen ground have little effect upon the distribution of trace elements associated with the Cleary H i l l vein. A new method for the determination of zinc using dilute acid is proposed. Analysis of geochemical data by trend surface procedures proved effective for localization of anomalies.
    • Trace element copper distribution and areal geology in a portion of the Clearwater Mountains, Alaska

      Glavinovich, P.S. (University of Alaska Mineral Industry Research Laboratory, 1967)
      The study concerns that portion of the Clearwater Mountains defined by north latitudes 63' 03' and 63' 08' and west longitudes 147' 09' and 147' 30'. Outcrop within the area consists predominantly of a sequence of intercalated andesitic and basaltic flows. Sedimentary rocks are present but comprise a very small percentage of the total section. Dikes and a small pluton are also present. The prevailing attitude of the volcanic and sedimentary rocks is east-northeast with a consistent north dip. A Triassic age is accepted for the volcanic and sedimentary rocks. Areal and local sampling indicates that all rock types are abnormally high in trace copper content, and average background is 1000 ppm. Copper distribution suggests a syngenetic origin. Frequent small copper deposits crop out along the north side of the area. The deposits are epigcnctic and are structurally controlled. The origin of these deposits may have potential exploration significance.

    • Applications of trend surface analysis and geologic model building to mineralized districts in Alaska

      Heiner, L.E.; Wolff, E.N. (University of Alaska Mineral Industry Research Laboratory, 1967)
      The Mineral Industry Research Laboratory, University of Alaska, has investigated the application of computers and statistics to mineral deposits in Alaska. Existing programs have been adapted and new ones written for the computers available at the University. The methods tested are trend surface analysis and geologic model making. An existing coeffecient of association program was converted to Fortran IV , but was not applied to an Alaskan problem. A trend surface is a mathematically describable surface that most closely approximates a surface representing observed data. In geologic model making, regression analysis is used to determine what geologic features are significant as ore controls. Coefficient of association compares samples to each other on the basis of a variable being present or absent. Trend surfaces were computed for dips and s t r i k e s of geologic features ( v e i n s , f a u l t s , bedrock) for Southeastern Alaska, the Chichagof district , and the Hyder district . Results for the f i r s t two are presented as maps. Trend surfaces and residual maps were prepared for geochemical data from the Slana district, Alaska. A mineral occurrence model was made for a portion of the Craig Quadrangle, and potential values were computed for c e l l s in the area. Appraisals of potential values by five geologists are compared with those of the model. An IBM 1620 multiple regression program is included.

    • Saline Conversion and Ice Structures from Artificially Grown Sea Ice

      Peyton, H. R.; Johnson, P. R.; Behlke, C. E. (University of Alaska, Arctic Environmental Engineering Laboratory and University of Alaska, Institute of Water Resources, 1967-09)
      The environment of cold regions is generally viewed as inhospitable, primarily due to application of ideal processes and techniques suitable to temperate zones. The work herein is a step toward solving two environmental problems. The first involves the supply of inexpensive, potable water in Arctic regions, the lack of which is a severe detriment to development. Although water does exist in the Arctic, it is neither available in potable form during many months of the year nor does it occur in sufficient quantity near the point of use. Principally, this lack is caused by the aridness of the Arctic and the shallowness of fresh water sources which, for all practical purposes, do not exist but freeze completely each winter season. The remaining liquid water source is the sea. Arctic problems are then similar to other arid regions where the conversion of sea water to potable water or the transmission of potable water to desired locations is necessary. Cold temperatures generally preclude transmission except over very short distances. Desalination by freezing sea water is a much reported process and has been included among the desalination processes under study worldwide. The advantage of this method in the Arctic is the cold winter-time temperature for freezing and the existence of adequate solar energy in the summer for melting self purified ice. Power requirements are greatly reduced using these natural phenomena. The second aspect of this study concerns the use of artificially grown sea ice as a structural material, thinking primarily in terms of coastal facilities such as docks, jetties, islands, platforms, etc. At sufficiently high latitudes, the summer ablation can be controlled to the point where major structures can be maintained intact during the summer. The unit cost of material is quite low because of low energy requirements. The results of this study show that each of these sea water uses have considerable promise. Desalination to potable level was accomplished. Ice growth rates were obtained which indicate that ice structures of substantial size can be built.
    • A Program for the Collection, Storage, and Analysis of Baseline Environmental Data for Cook Inlet, Alaska

      Wagner, David G.; Murphy, R. Sage; Behlke, Charles E. (University of Alaska, Institute of Water Resources, 1968)
      The scope of this report is to provide a general, yet comprehensive, description of the Cook Inlet System which will serve as a basis for understanding the interrelated natural and man-made factors governing its future; to present a program of field research studies for the estuarine environment that will describe the existing state of the Inlet with respect to the water quality and biota; to provide a framework whereby the program of studies can be evaluated and redirected in light of the preliminary results; and, to provide a method of storing and analyzing the data from the investigations so that it can be made available to interested parties in the most efficient manner possible.
    • Development of a light-weight low cost self potential unit

      Zonge, K.L. (University of Alaska Mineral Industry Research Laboratory, 1968)
      A lightweight, low cost self-potential unit has been developed using solid state components. The parts for the basic unit including batteries, copper sulfate pots, and hookup wire costs approximately $70.00. The device is instant reading and weighs two pounds. The batteries used have a shelf life of ten years and an estimated operation life (based on continuous use for ten hours per day) of sixty days. This instrument was developed specifically for the Alaskan prospector who is concerned with weight and cost of field instrumentation.
