Paper coal in Indiana
G.K. Guennel, R.C. Neavel
1959, Science (129) 1671-1672
The foliated, papery texture of the upper third of an 18-inch coal seam in a strip mine near Rockville, Indiana, is attributable to matted plant cuticle. The cuticles of pinnules, pinnae, and rachides resemble Sphenopteris bradfordii Arnold and thus differ from the lycopsid stem cuticles of the Russian paper coal....
Ion exchange in clays and other minerals
Dorothy Carroll
1959, GSA Bulletin (70) 749-779
Ion exchange in clays and other minerals is dependent on the crystalline structure of the mineral and on the chemical composition of any solution in contact with the mineral. The structures of clay minerals and zeolites are briefly described to provide a background for the discussion of their ion-exchange reactions....
Recent saprolite
J. P. Minard
1959, Science (129) 1206-1209
Thick saprolite has formed in northern New Jersey since the last Pleistocene glacial stage....
Studies on the life cycle of Apatemon gracilis pellucidus (Yamag)
G. L. Hoffman
1959, Transactions of the American Fisheries Society (88) 96-99
A tetracotyliform metacercaria was found in the musculature of the brook stickleback (Eucalia inconstans). It is characterized by a tail‐like appendage on the cyst. The adult was reared in newly hatched chicks, and proved to be Apatemon gracilis pellucidus (Yamaguti, 1933). Attempts to infect snails, Physa, Stagnicola and Helisoma, were...
A Summary interpretation of geologic, hydrologic, and geophysical data for Yucca Valley, Nevada test site, Nye County, Nevada
Verl Richard Wilmarth, D.L. Healey, Alfred Clebsch Jr., I.J. Winograd, Isadore Zietz, H. W. Oliver
1959, Trace Elements Investigations 358
This report summarizes an interpretation of the geology of Yucca Valley to depths of about 2,300 feet below the surface, the characteristics features of ground water in Yucca and Frenchman Valleys, and the seismic, gravity, and magnetic data for these valleys. Compilation of data, preparation of illustrations, and writing of...
Field observations on effects of Alaska earthquake of 10 July 1958
D. Tocher, D. J. Miller
1959, Science (129) 394-395
The Alaska earthquake of 10 July 1958 was caused by movement on the Fairweather fault amounting to at least 21 1/2 feet horizontally and 3 1/2 feet vertically. Effects of strong shaking were evident over a large area in southeastern Alaska. In Lituya Bay an enormous wave, possibly resulting from...
The life-cycle of the digenetic trematode, Proctoeces maculatus (Looss, 1901) Odhner, 1911 (Syn. P. rubtenuis [Linton, 1907] Hanson, 1950), and description of Cerceria adranocerca n. sp
H. W. Stunkard, J. R. Uzmann
1959, Biological Bulletin (116) 184-193
The genus Proctoeces was erected by Odhner ( 191 1) to contain Distonium maculatuni Looss, 1901, from Labrus merula and Crenilabrus spp. at Triest. Odhner had found the parasite in Blennius ocellaris at Naples. One adult specimen from Chrysophrys bifasciata and two immature specimens from lulis lunaris taken in the...
Waterfowl sickness diagnoses in Minnesota, North Dakota, and Manitoba
Eugene F. Bossenmaier
1959, Journal of Wildlife Management (23) 113-115
This paper reports the results of an attempt to determine whether botulinus toxin or some other factor was responsible for avian sickness on water bodies in Minnesota, North and South Dakota, and at Whitewater Lake, Boissevain, Manitoba, in the summer of 1953....
Determination of uranium in zircon
F. Cuttitta, G. J. Daniels
1959, Analytica Chimica Acta (20) 430-434
A routine fluorimetric procedure is described for the determination of trace amounts of uranium in zircon. It employs the direct extraction of uranyl nitrate with ethyl acetate using phosphate as a retainer for zirconium. Submicrogram amounts or uranium are separated in the presence of 100,000 times the amount of zirconium....
