Water requirements of the carbon-black industry
Howard L. Conklin
1956, Water Supply Paper 1330-B
Carbon blacks include an important group of industrial carbons used chiefly as a reinforcing agent in rubber tires. In 1953 more than 1,610 million pounds of carbon black was produced, of which approximately 1,134 million pounds was consumed by the rubber industry. The carbon-black industry uses small quantities of water...
Floods of 1952 in California. Flood of January 1952 in the south San Francisco Bay region; Snowmelt flood of 1952 in Kern River, Tulare Lake, and San Joaquin River basins
S. E. Rantz, H.M. Stafford
1956, Water Supply Paper 1260-D
Two major floods occurred in California in 1952. The first was the flood of January 11-13 in the south San Francisco Bay region that resulted from heavy rains which began on the morning of January 11 and ended about noon January 13. This flood was notable for the magnitude of...
A dithizone method for the determination of lead in monazite
R. A. Powell, C. A. Kinser
1956, Trace Elements Investigations 630
In determining lead in monazite [(Ce,La,Th)PO4]--to be used as the basis for geologic age measurements--it was necessary to eliminate interferences due to the presences of phosphates of thorium and the rare-earth metals. The method, in which monazite samples are attacked with hot concentrated sulfuric acid, taken up with dilute nitric acid,...
Sub-glacial volcanic eruptions
Donald Edward White
1956, Trace Elements Memorandum 1089
The literature on sub-glacial volcanic eruptions and the related flood phenomena has been reviewed as a minor part of the larger problem of convective and conductive heat transfer from intrusive magma. (See Lovering, 1955, for a review of the extensive literature on this subject.) This summary of data on sub-glacial...
Uranium content and leachability of some igneous rocks and their geochemical significance
George J. Neuerburg, John C. Antweiler, Barrie H. Bieler
1956, Trace Elements Investigations 626
The uranium content and its leachability in 442 igneous rocks if wide variety were measured. Four-gram samples, crushed below 38 mesh, were leached in in 0.05 M HNO3 for half an hour at 80 to 85° C; the leachate and undissolved residue were analyzed fluorimetrically. This study explored the relation of...
Detailed mineral and chemical relations in two uranium-vanadium ores
Robert M. Garrels, E. S. Larsen III, A. M. Pommer, R. G. Coleman
1956, Trace Elements Investigations 635
Channel samples from two mines on the Colorado Plateau have been studied in detail both mineralogically and chemically. A channel sample from the Mineral Joe No. 1 mine, Montrose County, Colo., extends from unmineralized rock on one side, through a zone of variable mineralization, into only weakly mineralized rock. The unmineralized...
Reservoirs in the United States
N.O. Thomas, G. Earl Harbeck Jr.
1956, Water Supply Paper 1360-A
Reservoir storage facilities in the United States play an important part in the national economy. Storage facilities have enabled the country to utilize to a much fuller extent one of the most valuable natural resources: water. During recent years the construction of reservoirs has continued at a high rate. This...
