Magmatic differentiation in the Uwekahuna Laccolith, Kilauea Caldera, Hawaii
K. J. Murata, D.H. Richter
1961, Journal of Petrology (2) 424-437
Petrographic and chemicoal studies of a suite of rocks from the Uwekahuna laccolith of Kilauea Volcano show that the original mafic tholeiitic magma differentiated into tholeiitic picrite, tholeiitic olivine gabbro, and an aphanitic rock approaching quartz-basalt in composition. Mechanisms involved were an initial gravity settling of olivine and a final filter pressing of...
Jadeite deposits of the clear creek area, New Idria district, San Benito county, California
R. G. Coleman
1961, Journal of Petrology (2) 209-247
Tectonic inclusions within the New Idria serpentine body contain jadeite in two distinct assemblages: (1) Lenslike inclusions containing a monomineralic green jadeite core surrounded by a calc-silicate rim. (2) Jadeite veins cross-cutting albite-crossite schist inclusions. In these veins jadeite coexists with low albite; green jadeite (Jd 75 Ac+Di+He 25)...

Copper, vanadium, and uranium deposits in sandstone-their distribution and geochemical cycles
R. P. Fischer, J. H. Stewart
1961, Economic Geology (56) 509-520
Deposits of copper, vanadium, and uranium in nonmarine sandstones are numerous and widespread. Copper deposits, with or without uranium, are mainly resident in first-generation arkosic sandstones derived from granitic rock terrains; deposits rich in vanadium, with or without much uranium, are dominantly in second-generation sandstones derived from sedimentary rocks; and the uranium deposits with little...

Giant desiccation fissures on the Black Rock and Smoke Creek Deserts, Nevada
R. Willden, D. R. Mabey
1961, Science (133) 1359-1360
Open fissures, from 100 to several hundred feet apart, that have produced polygonal patterns on the Black Rock Desert, Nevada, are believed to be giant desiccation cracks resulting from a secular trend toward aridity in the last few decades. Similar features on the Smoke Creek Desert probably have the same...

Palæomagnetic evidence relevant to a change in the Earth's radius
Allan Cox, Richard R. Doell
1961, Nature (190) 36-37
IT is important to note that if, during an expansion of the Earth, each point on the surface were to move radially outward, then all sampling areas would have the same relative geographical co-ordinates before and after expansion. Palæomagnetic results could not be used to detect an expansion of this...

Renal coccidiosis in oldsquaws (Clangula hyemalis) from Alaska
J. Christian Franson, Dirk V. Derksen
1961, Journal of Wildlife Diseases (17) 237-240
Renal coccidiosis was found in 4 of 12 oldsquaw ducks (Clangula hyemalis) collected from the north slope of Alaska and Prince William Sound. Numerous 1 to 2 mm white foci were observed on the kidney surface of one bird. Microscopically, there was distention of renal tubules with oocysts, flattening of...

Lava temperatures in the 1959 Kilauea eruption and cooling lake
W.U. Ault, Jerry P. Eaton, D.H. Richter
1961, GSA Bulletin (72) 791-794
The 1959 summit eruption of Kilauea Volcano, Hawaii, filled the crater of Kilauea Iki with a lake of lava 365 feet deep. Temperatures of the erupting basalt ranged between 1060° and 1190°C. Temperatures down a 12.7-foot-deep hole, drilled into the crust of the lake 5 months after cessation...
Preliminary geologic report on the 1960 U.S. Expedition to Bellingshausen Sea, Antarctica
C. Craddock, H.A. Hubbard
1961, Science (133) 886-887
Thurston Peninsula, although largely snow covered, exposes massive to foliated dioritic rock and schist exhibiting northeast-trending structures. One basalt pebble was found. The adjacent continental shelf is cut by submarine valleys. Peter I Island, a dissected basaltic volcano 250 miles to the northeast, was visited....

Late pleistocene and recent accumulation of uranium in ground water saturated sandstone deposits
J.M. Rosholt
1961, Economic Geology (56) 423-430
Protactinium-231 and thorium-230 relations in several ground water saturated sandstones containing uranium ore indicate that much of the uranium has been accumulating in very recent times. Samples from the Hauber mine, Crook County, Wyoming, were selected to illustrate the concept of recent accumulation and the methods of calculation of the estimated minimum and maximum dates of the...
Ground-water control in the Neyveli lignite field, South Arcot district, Madras State, India
P.H. Jones, V. Subramanyam
1961, Economic Geology (56) 273-298
Unconsolidated deposits of the Cuddalore series of Miocene age underlie much of the coastal plain of southern Madras. Several lignite seams occur in a thick sequence of sand, gravel, and clay that dips seaward about 40 to 100 feet per mile. The principal seam of lignite mapped in the Neyveli area averages more than 50...

Correlation of tertiary formations of Alaska

1961, American Association of Petroleum Geologists Bulletin (45) 1801-1809
Recent stratigraphic and paleontologic studies have resulted in substantial revision of the age assignments and inter-basin correlations of the Tertiary formations of Alaska as given in both an earlier compilation by P. S. Smith (1939) and a tentative chart prepared for distribution at the First International Symposium on Arctic Geology...
