Potential hydrologic effects of developing coal and other geo-energy resources of Oregon; a review
W.C. Sidle
1981, Open-File Report 81-1014
Southwestern Oregon has several hundred million tons of good-quality minable coal. Because of the dip of the coal beds, the only economical method of mining would be by underground methods. In addition, minor occurrences of low-quality coal have been noted at more than 20 sites in both western and northeastern...

Dissolution of sphalerite in ferric chloride solution
Huai Su
1981, Open-File Report 81-609
The dissolution of sphalerite in acidic ferric chloride solution of polished flat surfaces and of spherical particle surface was investigated. Tests were conducted on sphalerite to study rate of dissolution by the effects of stirring speed, temperature, ferric and ferrous concentrations, purity, and particle size.Kinetic investigations were conducted in a...

Evaluation of major dike-impounded ground-water reservoirs, Island of Oahu, with a section on flow hydraulics in dike tunnels in Hawaii
Kiyoshi J. Takasaki, John F. Mink
1981, Open-File Report 81-1119
Ground-water reservoirs impounded by volcanic dikes receive a substantial part of the total recharge to ground water on the island of Oahu because they generally underlie the rainiest areas. They accumulate the infiltration from rainfall, store it temporarily, and steadily leak it to abutting basal reservoirs or to streams cutting...
