A generalized graphical method for evaluating formation constants and summarizing well‐field history
H.H. Cooper, C. E. Jacob
1946, Eos, Transactions, American Geophysical Union (27) 526-534
The capacities of a water‐bearing formation to transmit water under a hydraulic gradient and to yield water from storage when the water table or artesian pressure declines, are generally expressed, respectively, in terms of a coefficient of transmissibility and a coefficient of storage. Determinations of these two constants are almost...
Activities in tectonics of Research Committee of American Association of Petroleum Geologists
P.B. King
1946, Eos, Transactions, American Geophysical Union (27) 713-714
During 1945 and 1946, the Research Committee of the American Association of Petroleum Geologists, under the chairmanship of Shepard W. Lowman, has been engaged in “a reconnaissance survey of research in petroleum geology and allied sciences with explicit reference to exploration” in order “to formulate a comprehensive research program which...
Structural control of ore bodies in the Jefferson City area, Tennessee
A.L. Brokaw, Charles Leslie Jones
1946, Economic Geology (41) 160-165
The zinc deposits of the Jefferson City area are confined to the lower half of the Kingsport formation of the Knox group of rocks. They are on the southeast flank of a northeast-trending anticline which is partially overridden from the southeast by the Bays Mt. thrust sheet. The beds show...
Sedimentary and volcanic processes in the formation of high alumina clay
Victor T. Allen
1946, Economic Geology (41) 124-138
In the West, where volcanic materials are abundantly distributed among the rocks of the geologic column, the importance of sedimentary processes in the formation of high-alumina clays has not been fully appreciated. At Ione, Calif., Castle Rock, Wash., Whiteware, Mont., Hobart Butte and Mollala, Oreg., where the Geological Survey has...
Stages and epochs of mineralization in the San Juan Mountains, Colorado, as shown at the Dunmore Mine, Ouray County, Colorado
Vincent Cooper Kelley, Caswell Silver
1946, Economic Geology (41) 139-159
The Dunmore lode is localized along a persistent fissure zone over two miles long and averaging nearly 100 feet in width along the length of the Dunmore claim. The fault in which the lode is located offset the pre-Cambrian quartzite and slate walls about 4,500 feet prior to deposition of...
Preliminary chemical correlation of chromite with the containing rocks
Thomas P Thayer
1946, Economic Geology (41) 202-217
Chromite investigations of the U. S. Geological Survey since 1939 indicate that economic deposits of chromite rich in normative spinel ((Mg, Fe)Al 2 O 4 ) occur in peridotites which are closely associated with gabbro; high-chrome chromites occur in feldspar-free peridotites; and chromites rich in both normative chromite ((Mg, Fe)Cr 2 O 4 ) and magnetite (FeFe 2 O 4 ) are...
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...
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...
