The talc, soapstone, and asbestos deposits of Massachusetts
Newton Earl Chute
1969, Open-File Report 69-39
Several talc and soapstone deposits were worked in Massachusetts from about 1810 to 1922. Most of these deposits are in the Chester Amphibolite, or in serpentine lenses in or adjacent to the amphibolite along a belt that extends north-south across the State from Rowe to West Granville; it appears...
Solubility of aluminum in the presence of hydroxide, fluoride, and sulfate
Charles Elmer Roberson, John David Hem
1969, Water Supply Paper 1827-C
The total concentration of aqueous dissolved species of aluminum that will be present in equilibrium with microcrystalline gibbsite at various levels of complexing ligand concentration are shown graphically. The graphs can be used to estimate aluminum solubility, at 25?C and 1 atmosphere total pressure, when the pH of the solution,...
Stage-discharge characteristics of a Weir in a sand-channel stream
Don D. Gonzalez, C.H. Scott, James K. Culbertson
1969, Water Supply Paper 1898-A
A unique relation between water-surface elevation and water discharge usually does not exist for sand-channel streams. The relation is affected by changes in bed roughness and changes in bed elevation because of scour and fill. An artificial control on a sand-channel stream must control both the resistance to flow and...
Paleogene floras from the Gulf of Alaska
Jack A. Wolfe
1969, Open-File Report 69-323
Numerous collections of fossil plants from the Gulf of Alaska region were obtained from rocks that are well dated by marine mollusks. The mollusks indicate that the oldest possible age for the lowest plant assemblage is middle Eocene (Domengine) and that the youngest possible age for the highest Paleogene plant...
Water resources of Randolph and Lawrence Counties, Arkansas
A. G. Lamonds, Marion S. Hines, Raymond O. Plebuch
1969, Water Supply Paper 1879-B
Water is used at an average rate of almost 27 million gallons per day in Randolph and Lawrence Counties, and quantities sufficient for any foreseeable use are available. Supplies for the large uses--municipal, industrial, and irrigation--can best be obtained from wells in .he Coastal Plain part of the counties and...
Geographic map of the Southern Hijaz quadrangle, Kingdom of Saudi Arabia
Glen F. Brown, Roy O. Jackson
1969, IMAP 210-B
Prepared by the U.S. Geological Survey and the Arabian American Oil Company under the joint sponsorship of the Kingdom of Saudi Arabia and the U.S. Department of State. The revisions to this map are principally the revisions to roads and the additions of new place names as of May 1968. ...
Laboratory theory and methods for sediment analysis
Harold P. Guy
1969, Techniques of Water-Resources Investigations 05-C1
The diverse character of fluvial sediments makes the choice of laboratory analysis somewhat arbitrary and the pressing of sediment samples difficult. This report presents some theories and methods used by the Water Resources Division for analysis of fluvial sediments to determine the concentration of suspended-sediment samples and the particle-size distribution...
Platinum, palladium, and rhodium analyses of ultramafic and mafic rocks from the Stillwater Complex, Montana
Norman J. Page, Leonard Benjamin Riley, Joseph Haffty
1969, Circular 624
Analyses by a combination fire- assay-solution-optical-emission spectrographic method of 137 rocks from the Stillwater Complex, Mont., indicate that platinum, palladium, and rhodium are preferentially concentrated in chromitite zones. The A chromitite zone (21 samples) has an average of 988.9 ppb (pans per billion, 10-9) Pt, 2290.2 ppb Pd, and 245.9...
Sedimentary rocks of the coast of Liberia
Richard William White
1969, Open-File Report 69-318
Two basins containing sedimentary rocks o# probable Cretaceous age have been recognized near the coast of Liberia in the area between Monrovia and Buchanan; geophysical evidence suggests that similar though larger basins exist on the adjacent continental shelf. The oldest sedimentary unit recognized, the Paynesville Sandstone of possible early to...
Weighted triangulation adjustment
Walter L. Anderson
1969, Open-File Report 69-10
The variation of coordinates method is employed to perform a weighted least squares adjustment of horizontal survey networks. Geodetic coordinates are required for each fixed and adjustable station. A preliminary inverse geodetic position computation is made for each observed line. Weights associated with each observed equation for direction, azimuth, and...
Foraminiferal zonation and carbonate facies of the Mississippian and Pennsylvanian Lisburne Group, central and eastern Brooks Range, Arctic Alaska
Augustus K. Armstrong, Bernard L. Mamet, J. Thomas Dutro Jr.
1969, Open-File Report 69-14
The Lisburne Group carbonates of the central and eastern Brooks Range contain foraminiferal assemblages assigned to zones of Osage [late Tournaisian], Early Mississippian, to Atoka [early Moscovian], Middle Pennsylvanian age. Representatives of both Eurasiatic and American cratonic microfaunas permit correlation with the original Carboniferous type sections in western Europe as...
