Iwo Jima, in the western Pacific Ocean, consists of Motoyama, a broad volcanic cone, at the north, and Mt. Suribachi at the south, with an undulating isthmus between. Motoyama is largely light-gray-buff tuff. A thick andesitic lava flow under Suribachi, exposed in several places, is overlain by a thick deposit...
Batholith and associated rocks of Corona, Elsinore, and San Luis Rey quadrangles southern California
Esper S. Larsen Jr.
1948, GSA Memoirs
The batholith of Southern and Lower California is exposed continuously from near Riverside, California, southward for a distance of about 350 miles. In central Lower California it is covered in part by younger rocks, but discontinuous bodies extend to the southern end of Lower California, and hence the batholith is...

1947, Open-File Report 47-27-B
Laboratory and field data on electrochemical stabilization of clays, by three Russian authors, are here presented in translation. Abstracts of the Russian papers were published in May 1947 issue of the Engineering News Record (pp. 100-101). There exists also a small body of literature, in German and English, dealing with...
Electrochemical stabilization of clayey ground
B.A. Rzhanitzin, V.P. Sokoloff (translator)
1947, Open-File Report 47-27-A
Recently developed new methods of stabilization of weak grounds (e.g. the silicate treatment) are based on injection of chemical solutions into the ground. Such methods are applicable accordingly only to the kinds of ground that have the coefficient of filtration higher than 2 meters per 24 hours and permit penetration...

Suggestions as to future research in ground‐water hydrology
O. E. Meinzer
1947, Eos, Transactions, American Geophysical Union (28) 418-420
Determination of the ground‐water supply available from any aquifer or in any specified area requires not merely the application of specific quantitative methods but also a broad and accurate knowledge of the geologic, hydrologlc, and geochemical factors that are involved, and consideration of the economic and legal limitations. Further research...
Scheelite in the Boulder District, Colorado
Ogden Tweto
1947, Economic Geology (42) 47-59
Scheelite accompanies ferberite as an ore of tungsten at many localities in the Boulder tungsten district. It is only of accessory importance in most veins, but in a few mines it affects grade of the ore substantially. It occurs in small veins, in vugs, disseminated in sericitized rock, and in...
