An interpretation of water‐table fluctuations at four wells in Southern California
Fred Charles Ebert
1936, Eos, Transactions, American Geophysical Union (17) 371-378
The urban and agricultural development in most areas of southern California have depended on the underground water‐resources of which more and more use has been made. It has been estimated that in the South Coastal Basin during the summer 90 per cent of the water‐supply for irrigation and other purposes...
Extension of normals by precipitation‐data and by comparison with another stream
G. L. Parker
1936, Eos, Transactions, American Geophysical Union (17) 542-543
The factors affecting relationship between precipitation and consequent runoff are multitudinous and their interrelation is exceedingly complex. They vary widely from time to time and place to place. Basic data are meager and the weight to be given to any single factor is usually uncertain. Runoff‐characteristics of drainage‐areas within the...
The recovery of ground‐water levels in Nebraska in 1935
Leland K. Wenzel
1936, Eos, Transactions, American Geophysical Union (17) 370-371
A program of water‐level measurements in about 350 wells scattered throughout Nebraska was begun in 1934 by the United States Geological Survey in cooperation with the Conservation and Survey Division of the University of Nebraska (see L. K. Wenzel, A state‐wide program of periodic measurements of ground‐water level in Nebraska,...
Dissolved mineral matter in surface‐waters
W. D. Collins
1936, Eos, Transactions, American Geophysical Union (17) 252-253
The only unpublished comprehensive Geological Survey records of dissolved matter in surface‐waters are the results obtained in the study of the Colorado River and its tributaries since 1930. The records are mainly analyses of 10‐day composites of daily samples, although there are several analyses of spot‐samples from some streams in...
Hydrothermal leaching in the Virginia mining district, New Mexico
Samuel Grossman Lasky
1936, Economic Geology (31) 156-169
The tourmaline-copper deposits of the Virginia mining district, New Mexico, lie along veins that were plugged and reopened repeatedly during the process of mineral deposition. At some time between the second and third stages of deposition the solutions removed calcite, sericite, and chlorite from interstitial and included fragments of altered...
Nodular, orbicular, and banded chromite in northern California
W. D. Johnston Jr.
1936, Economic Geology (31) 417-427
IN I930 Mr. A. F. Duggleby gave me a specimen of orbicular chromite from the Octopus claim, in Siskiyou County, Calif., showing two generations of chromite, one older than the associated olivine and one younger. In November, I93I, I examined briefly a number of deposits in northern California, in search...
