Sulfur Dioxide And Particles In Quiescent Volcanic Plumes From Poás, Arenal, And Colima Volcanos, Costa Rica And Mexico, T. Casadevall, William I. Rose, William H. Fuller, William H. Hunt, Mark A. Hart, Jarvis L. Moyers, David C. Woods, Raymond L. Chuan, James P. Friend

Department of Geological and Mining Engineering and Sciences Publications

Measurements of SO₂ emission rates and concentrations and of particle distribution, size, shape, and composition were made in quiescent volcanic plumes emitted into the troposphere from Poás and Arenal volcanos, Costa Rica, and Colima volcano, Mexico. SO₂ emission rates were 700±180 metric tons per day (t/d) for Poás, 210±30 t/d for Arenal, and 320±50 t/d for Colima. The concentrations of SO₂ calculated from the COSPEC/lidar data were 5–380 ppb. Concentrations of SO₂measured directly by flame photometry were 10–250 ppb. Particles collected in the plumes with a quartz crystal microbalance impactor were mostly less than 3 …

Amatitlan, An Actively Resurging Cauldron 10 Km South Of Guatemala City, Richard L. Wunderman, William I. Rose

Department of Geological and Mining Engineering and Sciences Publications

A 14×16 km diameter collapse caldera has been recognized 10 km south of Guatemala City, Guatemala. The caldera is north of the presently active volcano Pacaya and west of Agua, a large stratovolcano. The caldera was not previously recognized because its eastern and western margins coincide with faults that outline the Guatemala City graben and because the northern margin of the caldera is buried by pyroclastic rocks. The existence of the northern caldera margin is now established by gravity data and a variety of geological observations including circumferential faults, hot springs, well-log data, and lithological changes in sedimentary rocks. A …

Estimating Particle Sizes, Concentrations, And Total Mass Of Ash In Volcanic Clouds Using Weather Radar, David M. Harris, William I. Rose

Department of Geological and Mining Engineering and Sciences Publications

Observations of the March 19, 1982 ash eruption of Mount St. Helens, made by the National Weather Service (NWS, Portland, Oregon) on 5-cm radar, were used to estimate the volume of the ash cloud (2000 ±500 km³), the concentration of ash (0.2–0.6 g m⁻³). and the total mass of ash erupted (3–10×10¹¹ g). The position of the cloud was also tracked by radar. Particle sizes in the ash cloud were estimated from settling velocities suggested by decreases in maximum ash cloud height with time as it moved away from the volcano. The March 19, 1982 …

Infiltration Through Reconstructed Surface Mined Spoils And Soils, A. D. Ward, Larry G. Wells, R. E. Phillips

Biosystems and Agricultural Engineering Faculty Publications

An extensive series of tests involving reconstructed profiles of spoil and topsoil material from a Western Kentucky surface mine site was conducted with a laboratory infiltrometer system. Infiltration through the reconstructed spoil profiles was very slow despite the coarse nature of the material. Low infiltration rates could be attributed to the material having a well-graded texture and to the high densities of the profiles. Infiltration through topsoil horizons was controlled, for the most part, by conditions at the surface. Following wetting, infiltration rates were primarily controlled by the hydraulic characteristics of the less permeable sub horizon of the spoil material. …

Research On Atmospheric Volcanic Emissions: An Overview, James P. Friend, Alan R. Bandy, Jarvis L. Moyers, William H. Zoller, Richard E. Stoiber, Arnold L. Torres, William I. Rose, M. Patrick Mccormick, David C. Woods

Department of Geological and Mining Engineering and Sciences Publications

The project "Research on Atmospheric Volcanic Emissions" is a unique effort by NASA and university scientists to investigate the detailed chemical nature of plumes from volcanic eruptions. The major goals of the project are to: 1) understand the impact major eruptions will have on atmospheric chemistry processes, 2) understand the importance of volcanic emissions in the atmospheric geochemical cycles of selected species, 3) use knowledge of the plume chemical composition to diagnose and predict magmatic processes. Project RAVE'S first mission used the NASA Lockheed Orion P-3 outfitted with equipment to measure concentrations of the gases SO₂, OCS, H …

Water-Soluble Material On Aerosols Collected Within Volcanic Eruption Clouds, David B. Smith, Robert A. Zielinski, William I. Rose, B. J. Huebert

Department of Geological and Mining Engineering and Sciences Publications

In February and March of 1978, filter samplers mounted on an aircraft were used to collect the aerosol fraction of the eruption clouds from three active Guatemalan volcanoes (Fuego, Pacaya, and Santiaguito). The samples were collected on Teflon (Fluoropore) filters with a nominal pore diameter of 0.5μm. The mass of air sampled by the filters ranged from 0.15 to 6.6 kg. The particulate material collected consisted of fragments of angular silicate ash and droplets of what is interpreted as dilute H₂SO₄ and HCl. After collection of the samples, each filter was rinsed with 60 ml of distilled-deionized …

Small Particles In Plumes Of Mount St. Helens, William I. Rose, Raymond L. Chuan, D. C. Woods

Department of Geological and Mining Engineering and Sciences Publications

Particles in the size range of 0.1–25 micrometers were sampled by aircraft carrying a quartz crystal microcascade in the Mount St. Helens plume on three dates in August and September 1980. Two of the sampling dates represented ‘typical’ emissions of the volcano between plinian eruptions. One sampling flight was made 1–4 hours before the small plinian eruption of August 7, 1980, when the plume had become discontinuous and visibly darker. Size distributions were determined, and individual particles were studied by using scanning electron microscopy. The plume sampled on August 7, before the eruption, contained mainly approximately 2 micrometer diameter silicic …

Determination Of The Total Grain Size Distribution In A Vulcanian Eruption Column, And Its Implications To Stratospheric Aerosol Perturbation, P. J. Murrow, William I. Rose, S. Self

Department of Geological and Mining Engineering and Sciences Publications

Grain size analysis of samples representing all sampleable portions of the airfall deposit produced by the Fuego volcano in Guatemala on 14 October 1974 form the basis for estimating the total grain size distribution of tephra from this eruption. The region enclosed by each isopach has a particular average grain size distribution which can be weighted proportionally to its percentage volume. The grain size of pyroclastic avalanche deposits produced during the eruption are also included. The total grain size distribution calculated as a sum of weighted distributions has a median grain size of 0.8∅ (0.6mm) and a sorting coefficient (σ∅) …

Umr Minerals Building: An Innovative Approach To The Construction Of Underground Buildings, Bruce H. Green, David A. Summers

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The original intent of the exercice was to develop a design for a new minerals engineering building which would demonstrate the applicability and feasibility of an underground building complex to our administration and to the Board of Curators. Two major advantages were foreseen for such a building. Not only would it be immensely superior, in terms of energy demand, to the conventional aboveground buildings previously constructed by the University, but it also would have highly significant symbollic and educational effects on the students of the several disciplines comprising the UMR "School of Mines and Metallurgy". It would also serve as …

Determination Of Washability And Flotation Characteristics Of Important Missouri Coal Seams, Hayri Erten

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Most of the 14 workable coal seams in the State of Missouri are considered to be high in ash and sulfur contents and need beneficiation in order to meet customer and Environmental Protection Agency requirements. If proper beneficiation methods can be designed, more Missouri coal will be mined and used within the state.

The objectives of this research are (1) to draw the washability curves of important Missouri coal seams in order to determine their washability characteristics, and (2) to determine the flotation characteristics of the same seams.

Tests conducted on 20 samples taken from Bevier, Croweburg, Mulky, and Summit …
