Possible uranium mineralization, Mineral Mountains, Utah
W. Roger Miller, John B. McHugh, Walter H. Ficklin
1979, Open-File Report 79-1354
The Mineral Mountains block in west-central Utah is a horst whose core stands structurally high relative to all nearby basin-and-range fault blocks. Rocks of the Mineral Mountains range from Precambrian to Quaternary in age, but mostly consist of Tertiary granitic rocks. The range lies with the Wah Wah-Tusher mineral belt....

The southern Powder River area comprises about 2,230 square miles in southeastern Montana. Sedimentary rocks beneath this area range in age from Cambrian to Holocene and attain a maximum thickness of about 12,000 feet. Rocks exposed in the study area range in age from Late Cretaceous to Holocene.Water for domestic,...
The importance of dissolved free oxygen during formation of sandstone-type uranium deposits
Harry Clifford Granger, C. G. Warren
1979, Open-File Report 79-1603
One factor which distinguishes t, he genesis of roll-type uranium deposits from the Uravan Mineral Belt and other sandstone-type uranium deposits may be the presence and concentration of dissolved free oxygen in the ore-forming. solutions. Although dissolved oxygen is a necessary prerequisite for the formation of roll-type deposits, it is...
Water resources of the Marquette Iron Range area, Marquette County, Michigan
N.G. Grannemann
1979, Open-File Report 79-1339
Dependable water supplies are vital to the mining industry in the Marquette Iron Range in Michigan. Development of processes that concentrate and pelletize low-grade iron ore has permitted mining to expand during the past two decades. Water demand has increased both for iron ore concentration processes and for the area...
Geology and physiography of the continental margin north of Alaska and implications for the origin of the Canada Basin
Arthur Grantz, Stephen L. Eittreim, O.T. Whitney
1979, Open-File Report 79-288
The continental margin north of Alaska is of Atlantic type. It began to form probably in Early Jurassic time but possibly in middle Early Cretaceous time, when the oceanic Canada Basin of the Arctic Ocean is thought to have opened by rifting about a pole of rotation near the Mackenzie...
Urban storm-runoff modelling; Madison, Wisconsin
R. Stephen Grant, Gerald Goddard
1979, Open-File Report 79-1273
The Illinois Urban Drainage Area Simulator was used to analyze the effects that (1) physical changes to storm-sewer conduits, and (2) increased runoff detention and infiltration would have on storm runoff in four urban basins in Madison, Wisconsin. The model was calibrated using monitoring data for the four basins collected...

Reconnaissance geology of the Wadi Shuqub Quadrangle, sheet 20/41 A, Kingdom of Saudi Arabia
Robert C. Greene, Louis Gonzalez
1979, Open-File Report 79-1353
The Wadi Shuqub quadrangle (sheet 20/41 A) lies in the high mountainous part of the Hijaz plateau in west-central Saudi Arabia. The quadrangle is underlain chiefly by Precambrian layered metasedimentary and metavolcanic rocks that are intruded by plutons ranging in composition from gabbroic to granitic. The metasedimentary rocks include quartzite,...
Seismic studies at the Mt. Hood Volcano, northern Cascade Range, Oregon
Susan Molly Green, Craig S. Weaver, Hariharaiyer Mahadeva Iyer
1979, Open-File Report 79-1691
A sixteen station telemetered seismic network was established in the Mt. Hood, Oregon area to monitor local seismicity and to study crustal and upper mantle structure. The network was in operation 13 months, and recorded 10 local earthquakes, 25 regional events, and 300 teleseisms. A series of construction blasts were...

James Louis Gualtieri
1979, Open-File Report 79-999
Four holes were drilled in the Book Cliffs coal region of Garfield County, Colorado and Grand County, Utah to provide coal core samples suitable for analysis and stratigraphic information about coal-bearing strata. Three of the holes were completed; the fourth remains to be completed; a fifth is planned. A total...

Assessment of potential impacts to the hydrologic system related to surface mining
R. F. Hadley
1979, Open-File Report 79-1598
With the increasing demand for energy minerals, such as coal and uranium, and other minerals, Indian lands have received the attention of leasing, exploration, and mining interests. If these mineral resources, together with all other land resources, are to be managed properly by tribal decisionmakers, they will need more information....
