Surface Water Records of California, 1961; Volume 2: Northern Great Basin and Central Valley
Water Resources Division, U.S. Geological Survey
1961, Water Data Report CA-61-2
The surface-water records for the 1961 water year for gaging stations, partial-record stations, and miscellaneous sites within the State of California are given in this report. For convenience there are also included records for a few pertinent gaging stations in bordering States. The records were collected and computed by the...
Sulfide ores formed from sulfide-deficient solutions 1
T. S. Lovering
1961, Economic Geology (56) 68-99
Assuming that many hydrothermal ore deposits are formed from emanations given off from a magma at depth while it cools through the interval in which latent heat of crystallization is generated, it is shown that this cooling interval for magmatic bodies of moderate size must be measured in tens or hundreds of...

The data of lead isotope geology related to problems of Ore Genesis
R.S. Cannon Jr., A.P. Pierce, J.C. Antweiler, K.L. Buck
1961, Economic Geology (56) 1-38
Searching questions about the origins of ore deposits have been asked for many years. Where do ore fluids originate-within the crust, or deeper? Can specific sources of ore metals be identified? When were ores deposited? How long did mineralization continue? What was the rate and paragenesis of deposition? Which deposits are cogenetic, and...
