Magnetometer Surveys: Attempts And Issues In Locating A 1948 Private Water Well On The Shore Of Lac Sault Dore, Price County, Wisconsin, Kenneth R. Neuhauser, Kristopher J. Neuhauser 2014 College of Saint Benedict and Saint John’s University

Magnetometer Surveys: Attempts And Issues In Locating A 1948 Private Water Well On The Shore Of Lac Sault Dore, Price County, Wisconsin, Kenneth R. Neuhauser, Kristopher J. Neuhauser

The Compass: Earth Science Journal of Sigma Gamma Epsilon

Two different magnetometer surveys in northern Wisconsin during the summers of 1997 and 2010, using two different Geometrics magnetometers, a proton precession G-816 unit and a cesium vapor G-858 unit, in an attempt to locate a surface-target position of, and depth to, an abandoned 1948 private water well, successfully targeted the suspect surface position and the depth to the well head spike. Both surveys detected 400-gamma anomalies and estimated the depth to the spike at 2 meters. A land owner, private family photograph taken in 1951, was used to compare the anomaly’s position to the actual surface position of ...

A Surface Chemistry Study Of The Effects Of Zinc Sulphate On Sphalerite During Flotation Separation At The Laronde Mine, Dennis M. Laliberty 2014 Western University

A Surface Chemistry Study Of The Effects Of Zinc Sulphate On Sphalerite During Flotation Separation At The Laronde Mine, Dennis M. Laliberty

University of Western Ontario - Electronic Thesis and Dissertation Repository

The LaRonde mine is a gold-rich VMS deposit in the Abitibi Greenstone Belt of Canada. Like many polymetallic ore deposits, loss of sphalerite occurs during the Cu circuit of flotation separation at the mill. Zinc sulphate was tested as a sphalerite depressant. XRD, TOF-SIMS and XPS were used to examine the mineralogy and surface chemistry of ore samples collected at select stages of the milling process in the mill and in the laboratory. Data analyses showed that ZnSO4 likely promotes sulphoxyl and hydroxide adsorption to the sphalerite surface inhibiting Cu activation. Addition of ZnSO4 in the LaRonde mill has reduced ...


Comparing Near-Regional And Local Measurements Of Infrasound From Mount Erebus, Antarctica: Implications For Monitoring, A. L. Dabrowa, D. N. Green, J. B. Johnson, J. C. Phillips, A. C. Rust 2014 Boise State University

Comparing Near-Regional And Local Measurements Of Infrasound From Mount Erebus, Antarctica: Implications For Monitoring, A. L. Dabrowa, D. N. Green, J. B. Johnson, J. C. Phillips, A. C. Rust

Geosciences Faculty Publications and Presentations

Local (100s of meters from vent) monitoring of volcanic infrasound is a common tool at volcanoes characterized by frequent low-magnitude eruptions, but it is generally not safe or practical to have sensors so close to the vent during more intense eruptions. To investigate the potential and limitations of monitoring at near-regional ranges (10s of km) we studied infrasound detection and propagation at Mount Erebus, Antarctica. This site has both a good local monitoring network and an additional International Monitoring System infrasound array, IS55, located 25 km away. We compared data recorded at IS55 with a set of 117 known Strombolian ...


Evidence Of Large Scale Tectonic Processes On The Tharsis Rise, Mars, Genevieve Kidman, John S. MacLean, David Maxwell 2014 College of Saint Benedict and Saint John’s University

Evidence Of Large Scale Tectonic Processes On The Tharsis Rise, Mars, Genevieve Kidman, John S. Maclean, David Maxwell

The Compass: Earth Science Journal of Sigma Gamma Epsilon

Past observations of Mars have led scientists to believe that tectonic kinematics stopped early in its planetary development. Recent exploration of Mars has led to new theories that support an active tectonic regime on the Tharsis rise. With the advancement of new satellite imagery and technologies such as Thermal Emission Imaging System, High Resolution Imaging Science Experiment satellite imagery, the Mars Orbital Laser Altimeter, and interactive software such as J-Mars and Esri GIS, we have identified additional large-scale surface features in the Tharsis Rise and surrounding areas. Large-scale Martian lineations, folds, and conjugate joints can be compared to similar structures ...

K. Dots To Data: Manufacturing Digital Seismic Traces From Scanned Images Of The Paper Sign Bit: Sections From The 1970 Flathead Lake Seismic Survey, Robert W. Lankston 2014 University of Montana

K. Dots To Data: Manufacturing Digital Seismic Traces From Scanned Images Of The Paper Sign Bit: Sections From The 1970 Flathead Lake Seismic Survey, Robert W. Lankston

Flathead Lake Seismic Survey

This lecture was presented by Robert W. Lankston on October 13, 2014 in the University of Montana, Department of Geosciences Colloquium Lecture Series.

The thesis is offered that more value can be gained from the 1970 Flathead Lake seismic sections if they are converted to digital traces and georegistered for easy use in a modern seismic workstation and for processing with modern deconvolution and migration tools. A time line with three segments from the early 1960’s to the present shows the mid-1960’s to mid-1970’s era that includes the summer when the Flathead Lake data were recorded, a ...


Luminescence Dating Without Sand Lenses: An Application Of Osl To Coarse-Grained Alluvial Fan Deposits Of The Lost River Range, Idaho, Usa, M. K. Kenworthy, T. M. Rittenour, J. L. Pierce, N. A. Sutfin, W. D. Sharp 2014 Boise State University

Luminescence Dating Without Sand Lenses: An Application Of Osl To Coarse-Grained Alluvial Fan Deposits Of The Lost River Range, Idaho, Usa, M. K. Kenworthy, T. M. Rittenour, J. L. Pierce, N. A. Sutfin, W. D. Sharp

Geosciences Faculty Publications and Presentations

Optically stimulated luminescence (OSL) dating is increasingly used to estimate the age of fluvial deposits. A significant limitation, however, has been that conventional techniques of sampling and dose rate estimation are suitable only for thick (>60 cm) layers consisting of sand size or finer grains. Application of OSL dating to deposits lacking such layers remains a significant challenge. Alluvial fans along the western front of the Lost River Range in east-central Idaho, USA are one example. Deposits are typically pebble to cobble sheetflood gravels with a sandy matrix but thin to absent sand lenses. As a result, the majority of ...


The Spatial Cross-Correlation Method For Dispersive Surface Waves, Andrew P. Lamb, Kasper van Wijk, Lee M. Liberty, T. Dylan Mikesell 2014 Boise State University

The Spatial Cross-Correlation Method For Dispersive Surface Waves, Andrew P. Lamb, Kasper Van Wijk, Lee M. Liberty, T. Dylan Mikesell

Geosciences Faculty Publications and Presentations

Dispersive surface waves are routinely used to estimate the subsurface shear-wave velocity distribution, at all length scales. In the well-known Spatial Autocorrelation method, dispersion information is gained from the correlation of seismic noise signals recorded on the vertical (or radial) components. We demonstrate practical advantages of including the cross-correlation between radial and vertical components of the wavefield in a spatial cross-correlation method. The addition of cross-correlation information increases the resolution and robustness of the phase velocity dispersion information, as demonstrated in numerical simulations and a near-surface field study with active seismic sources, where our method confirms the presence of a ...


Quantifying Submarine Eruptive Flux From Interpretation Of Hydroacoustic Signals, West Mata Volcano, Lau Basin, Chelsea Joy Mack 2014 Western Washington University

Quantifying Submarine Eruptive Flux From Interpretation Of Hydroacoustic Signals, West Mata Volcano, Lau Basin, Chelsea Joy Mack

WWU Masters Thesis Collection

West Mata is a submarine volcano in the northeast Lau Basin. Hydroacoustic data from a 5-month period provide insight into the nature of eruptive behavior at this volcano. Previous studies have used acoustic data to estimate the eruption velocity at subaerial volcanoes (Woulff and McGetchin, 1976; Vergniolle et al., 2004; Vergniolle and Caplan- Auerbach, 2004, 2006; Caplan-Auerbach et al., 2010). In this study, the hydroacoustic data from West Mata are used to calculate eruption velocities and volumes (both lava and gas) for explosions during the 5-month hydrophone deployment. The method used in this study, developed by Vergniolle and Caplan-Auerbach (2006 ...


Three-Dimensional Deformable Pore Networks, Jack W. Conrad, Laura J Pyrak-Nolte 2014 Purdue University

Three-Dimensional Deformable Pore Networks, Jack W. Conrad, Laura J Pyrak-Nolte

The Summer Undergraduate Research Fellowship (SURF) Symposium

Porous structures in materials play a part in many areas of research and development. A couple of examples of this are extraction of water through aquifers and oil through fracking processes. Current understanding of the small scale fluid-fluid interactions in the structure of these porous materials stops at data of the two dimensional interface between the two fluids. This experiment aimed to create three dimensional, transparent, deformable micro-models which are expected allow us to obtain three dimensional data sets of the capillary pressure–saturation–interfacial area per volume relationship. The micro-models were synthesized using a grain deposition technique. Grains were ...

Earth History Visualization System, Xinjie Lei, James G. Ogg

The Summer Undergraduate Research Fellowship (SURF) Symposium

Time Scale Creator (TSCreator), a geological chart generator, displays any portion of Earth history including chemo- magneto-, and other aspects. TSCreator is used by many universities, petroleum companies, and international geological surveys. In order to improve the quality of Time Scale Creator, tools were developed to provide users with more friendly graphical user interfaces (GUIs), accurate scaling of specific isotope, internationalization of data input and output, and smart depth scaling in wells to age conversion. To implement such tools, research for algorithm and common methods was basically done by searching articles online and reading posts on forums for Java developers ...


Cosmogenic Radionuclides In Ice Cores From West Antarctica, Zhijie Chen, Thomas Edward Woodruff, Marc W. Caffee 2014 Purdue University

Cosmogenic Radionuclides In Ice Cores From West Antarctica, Zhijie Chen, Thomas Edward Woodruff, Marc W. Caffee

The Summer Undergraduate Research Fellowship (SURF) Symposium

Cosmogenic nuclides such as 10Be and 26Al are formed in the atmosphere by cosmic rays and come down to the ground through snow which became ice in Antarctica. The concentrations of 10Be and 26Al in ice cores can reveal important information about climate change, solar activity and geomagnetic change in the past. They can also be used to date very old ice. Since there is very little 26Al in the ice, its actual concentration is poorly known and the measured results don’t agree with each other. My research is focused on the measurement of ...


Air Mass Frequency During Precipitation Events In The Northern Plains Of The United States, Anthony Baum, Richard De Pasquale, Melissa L. Godek 2014 College of Saint Benedict and Saint John’s University

Air Mass Frequency During Precipitation Events In The Northern Plains Of The United States, Anthony Baum, Richard De Pasquale, Melissa L. Godek

The Compass: Earth Science Journal of Sigma Gamma Epsilon

Since 1980, numerous billion-dollar disasters have affected the Northern Plains of the United States, including nine droughts and four floods. The atmospheric environment present during precipitation events can largely be described by the presiding air mass conditions since air masses characterize a multitude of meteorological variables at one time over a large region. The goal of this research is to add knowledge to current understandings of the factors responsible for precipitation in the Northern Plains through an assessment of synoptic air mass conditions. The Spatial Synoptic Classification is used to categorize 30 years of daily surface air mass types across ...
