General principles of artificial ground-water recharge
O. E. Meinzer
1946, Economic Geology (41) 191-201
The natural subterranean reservoirs formed by the porous and permeable rocks differ from surface reservoirs chiefly in that they have complex structure and great internal resistanc• to the How of water. Their full utilization requires systematic development based on the geology and hydrology of the aquifer and the principles of...

Artificial recharge of artesian limestone at Orlando, Florida
A.G. Unklesbay, H.H. Cooper
1946, Economic Geology (41) 293-307
The principal aquifer in the Orlando area consists of 900 feet or more of permeable artesian limestones of upper and middle Eocene age. As in most other parts of the Florida peninsula, these limestones are overlain by the Hawthorn formation of Miocene age which contains relatively impervious beds. The Hawthorn...
A cotangent ruler for simplifying the graphic solution of problems in structural geology
Walter S. White
1946, Economic Geology (41) 539-545
The cotangent ruler is a device for measuring directly the dip of contoured surfaces, or, conversely, for constructing contours that represent planes of known dip. It greatly simplifies the graphic solution of problems in structural geology, and has several specialized applications to problems commonly encountered in mining geology and areal...
Artificial recharge of glacial sand and gravel with filtered river water at Louisville, Kentucky
W.F. Guyton
1946, Economic Geology (41) 644-658
Records obtained by the Geological Survey, United States Department of the Interior, and the Geological Division, Kentucky Department of Mines and Minerals, indicate that industries at Louisville pumped about 62 million gallons of water per day from wells in 1943. This was over 20 million gallons a day more than...
The quartz crystal deposits of western Arkansas
A.E.J. Engel
1946, Economic Geology (41) 598-618
Extensive geological investigations of domestic deposits of quartz crystals were undertaken by the Geological Survey of the United States Department of the Interior in the fall of 1942 in response to the urgent demand for crystals for war purposes. The work was continued throughout 1943 and took survey geologists into...
Artificial recharge of productive ground-water aquifers in New Jersey
H.C. Barksdale, G.D. DeBuchananne
1946, Economic Geology (41) 726-737
Artificial recharge by water spreading is practiced in several places in New Jersey. Rates of recharge ranging from 3,000 to 125,000 gallons per acre per day have been measured at the Perth Amboy Water Works, where artificial recharge of the Old Bridge sand, of upper Cretaceous age, has been practiced...
Hydrothermal alteration in the Castle Dome copper deposit, Arizona
Nels P. Peterson, Charles Gilbert, G.L. Quick
1946, Economic Geology (41) 820-840
Hydrothermal alteration of the quartz monzonite host rock in the Castle Dome copper deposit consists of three phases. Very weak propylitic alteration of biotite and plagioclase occurs in the marginal part of the mineralized area. Where mineralization is stronger most of the plagioclase and some of the orthoclase and biotite...
