Mineralogy, Isotope Geochemistry And Geothermometry Of The Lowry Deposit, Black Butte Copper Project, Meagher County, Montana, John Allard
Graduate Theses & Non-Theses
The Black Butte Copper Project is a sedimentary rock hosted, Cu-rich massive sulfide deposit hosted in rocks of the ca. 1.5-1.325 Ga Mesoproterozoic Belt Supergroup. Copper-bearing sulfides, mainly chalcopyrite and tennantite, are hosted in debris flows, black shale, dolostone and sedimentary pyrite layers of the Newland Fm. of the Lower Belt Group in the Helena Embayment, an E-W striking limb of the greater NNW trending Belt Basin. Mineralization is hosted within two separate but contemporaneous deposits, Johnny Lee, which hosts Cu sulfides in an upper and lower sulfide zone within sedimentary pyrite and debris flow conglomerates, and Lowry, where Cu …
Geology And Geochronology Of The East Dome Complex Within The Hog Heaven Volcanic Field, Flathead County, Montana, Ethan Coppage
Geology And Geochronology Of The East Dome Complex Within The Hog Heaven Volcanic Field, Flathead County, Montana, Ethan Coppage
Graduate Theses & Non-Theses
This study describes the style and timing of volcanic activity and mineralization in the East Dome Complex (EDC) of the 55-km2 Eocene-Oligocene Hog Heaven Volcanic Field (~36-30 Ma; HHVF) located in northwestern Montana. The HHVF consists of three NE-aligned, predominantly high-K rhyodacitic dome complexes (1.8-4.9 wt. % K2O; 63.2-72.9 wt. % SiO2) formed near the crest the Purcell Anticlinorium, a major Cordilleran fold-thrust belt structure deforming metasedimentary rocks of the Mesoproterozoic Belt Supergroup. Dome emplacement was controlled by a NE-striking fault associated with a pull-apart basin formed between two overlapping, NW-trending dextral oblique-slip faults. The objective of this study is …
Mineralogy And Fluid Inclusion Study Of The Marget Ann Mine Of The Butte Mining District, Silver Bow County, Montana, Tiffany Ostenburg
Mineralogy And Fluid Inclusion Study Of The Marget Ann Mine Of The Butte Mining District, Silver Bow County, Montana, Tiffany Ostenburg
Graduate Theses & Non-Theses
Butte, Montana, is a famous example of a zoned, polymetallic, porphyry-lode deposit. Whereas over a century of previous work has focused on the porphyry-style mineralization and centrally located, copper-rich lode deposits, relatively little has been written on the outer, silver-rich veins. The Marget Ann mine, in the northern portion of the district, was chosen for this study because of ease of access to the mine dumps as well as archived samples of high-grade vein mineralization. In addition, the Marget Ann mine is somewhat unique in Butte because gold has been found there and previously recorded in the veins. The main …
An Examination Of The Impacts Of Beaver Dam Mimicry Structures On Groundwater Surface-Water Interactions In Lower Mountain Riparian Systems, Mercedes D. Salazar
An Examination Of The Impacts Of Beaver Dam Mimicry Structures On Groundwater Surface-Water Interactions In Lower Mountain Riparian Systems, Mercedes D. Salazar
Graduate Theses & Non-Theses
Beaver dam analogs (BDAs) are a low cost, low disturbance stream restoration technique that may improve surface-water/groundwater interactions and wetland connectivity. BDAs are intended to imitate the effects of natural beaver dams by slowing stream velocity, promoting infiltration, increasing dry-season streamflow, aggrading the streambed, and capturing organic matter and other nutrients. This study was conducted to evaluate the degree to which these objectives were being met at a study site on Perkins Gulch, southwest Montana, USA. The Perkins Gulch study area can be summarized by four gauging sites that separate three reaches along the creek. By detailing background processes and …
Surface Water/Groundwater Interactions And Hydrogeochemical Characterization Of The Elkhorn Mine And Mill, Beaverhead County, Montana, Tyler Kamp
Graduate Theses & Non-Theses
The formation of acid mine drainage (AMD) and the contaminants associated with it have been described by some as the largest environmental problem facing the U.S. mining industry. Heavy metals associated with the drainage, such as copper, cadmium, and zinc affect the water quality of streams and can cause acute or chronic toxicity to invertebrates and fish (Martin, 1992& Padrillah et al., 2018). Elkhorn Creek in the Pioneer Mountains of southwest Montana is one of these impacted creeks. The historic Elkhorn Mine and Mill complex has historically attributed to the creek’s contamination and has undergone remediation. However, the problem has …
