Zinc-copper deposits near Moth Bay, Revillagigedo Island, southeastern Alaska
G. D. Robinson
1944, Open-File Report 44-88
Moth Bay is a narrow inlet on the north side of the entrance to Thorne Arm, a large bay near the southern end of Revillagigedo Island, southeastern Alaska (see insert, fig. 1). It is about 16 miles by water southeasterly from Ketchikan, the nearest port. Moth Bay is locally known...
The fluorspar deposits of Saint Lawrence, Newfoundland
Ralph Erskine Van Alstine
1944, Economic Geology (39) 109-132
Fluorspar from Newfoundland, eighth ranking producer of the world, comes entirely from the St. Lawrence district. Here pre-Cambrian lavas and pyroclastics, Cambrian sedimentary rocks, Ordovician (?) volcanic and sedimentary rocks, and a Paleozoic alaskite-granite comprise the bedrock.Epithermal fluorite veins occupy steeply dipping fault fissures in granite, rhyolite porphyry, and lamprophyre....
Bachman's sparrow in Maryland
R. E. Stewart, B. Meanley
1943, The Auk (60) 605-606
The Bachman's Sparrow (Aimophila aestivalis bachmani) is known to be quite rare and irregular in distribution in the northern part of its range. Because of this the northern limits of its range have been rather ill-defined. According to the A. 0. U. Check-List, Fourth Edition: 343, 1931, this bird ranges...
Igneous rocks of the Highwood Mountains, Montana: Part VI. Mineralogy
E.S. Larsen, C.S. Hurlbut, Bennett Frank Buie, C.H. Burgess
1941, GSA Bulletin (52) 1841-1856
The minerals of the igneous rocks of the Highwood Mountains are described. The primary hornblende of the quartz latites is basaltic and it has been partly replaced by a common green hornblende. Hornblende is rare in the alkalic rocks. Augite is an abundant mineral of the alkalic rocks; in the...
Rare chemical constituents of amelia (Virginia) pegmatite dikes, and their mineral sources
Jewell J. Glass
1934, Eos, Transactions, American Geophysical Union (15) 234-237
Students of Igneous phenomena have long since become familiar with the occurrence of rare minerals in pegmatitic bodies. The great local concentration of rare elements in pegmatite minerals provides a remarkably good opportunity for the Investigation of deep-seated rock constituents, for it is reasonable to suppose that these same elements...
Determination of the common and rare alkalies in mineral analysis
R. C. Wells, R.E. Stevens
1934, Industrial And Engineering Chemistry Analytical Edition (6) 439-442
Methods are described which afford a determination of each member of the alkali group and are successful in dealing with the quantities of the rare alkalies found in rocks and minerals. The procedures are relatively rapid and based chiefly on the use of chloroplatinic acid, absolute alcohol and ether, and...
Guidebook of the western United States: Part F - The Southern Pacific lines, New Orleans to Los Angeles
Nelson Horatio Darton
1933, Bulletin 845
The Southern Pacific Railroad from New Orleans to Los Angeles, a distance of about 2,000 miles, passes through a region exhibiting a great variety of geographic and industrial conditions. The climate, especially the amount of precipitation, is the most influential factor in causing this variety. The low Coastal Plain of southern...
Geology and ore deposits of the Pioche district, Nevada
L.G. Westgate, Adolph Knopf
1932, Professional Paper 171
LOCATION AND SURFACE FEATURES The Bristol Range, Highland, and Ely Range quadrangles make up the larger part of a. rectangular area 35 miles north and south by 24 miles east and west, which lies 19 miles west of the Nevada-Utah line and about 250 miles southwest of Salt Lake...
Manganese-bearing deposits near Lake Crescent and Humptulips, Washington
J. T. Pardee
1927, Bulletin 795-A
The Crescent mine, situated a short distance west of Lake Crescent, in the Olympic Mountains of Washington, yields an unusually high grade of manganese ore, which is suitable for making steel. Several manganiferous lodes of promising appearance have been found in the same area, and some near Humptulips, on the...
Some American Cretaceous fish scales, with notes on the classification and distribution of Cretaceous fishes
T.D.A. Cockerell
1919, Professional Paper 120-I
Fish remains are extremely abundant in several Cretaceous formations of the Rocky Mountains and Great Plains, but except in the Niobrara formation of Kansas, a fish skeleton well enough preserved for description or identification is the greatest rarity. The fishes are represented by separate scales, in some places associated...

Baked shale and slag formed by the burning of coal beds
G. Sherburne Rogers
1918, Professional Paper 108-A
The baking and reddening of large masses of strata caused by the burning of coal beds is a striking feature of the landscape in most of the great western coal-bearing areas. The general character and broader effects of the burning have been described by many writers, but the fact that...
Glaciers of Glacier National Park
William C. Alden
1914, Report
Glacier National Park derives its name and much of its interest from the presence of many small glaciers. Very much of the grandeur of its wonderful Alpine scenery, the final sculpturing of the great mountain valleys and of the amphitheaters at their heads, and the production of the basins of...

Index to the known fossil insects of the world, including myriapods and arachnids
Samuel Hubbard Scudder
1891, Bulletin 71
With the view of furthering study in the too neglected field of fossil insects, I transmit herewith for publication the card catalogue of described fossil insects which I have used for twenty years and kept constantly up to date, and which has greatly facilitated my own researches. It is believed...
Geology of the Henry Mountains
G. K. Gilbert
1877, Report
If these pages fail to give a correct account of the structure of the Henry Mountains the fault is mine and I have no excuse. In all the earlier exploration of the Rocky Mountain Region, as well as in much of the more recent survey, the geologist has merely accompanied...
Notes on the geology of northeastern New Mexico
O. St. John
1876, Report, Bulletin of the United States Geological and Geographical Survey of the Territories
In the region of the headwaters of the Canadian is embraced a territory which, for the completeness of its geological record and the interest of its concomitant topographical and scenic features, is not excelled perhaps by a similar extent of country in the West. It is bounded on the west...
Characterizing the two-dimensional thermal conductivity distribution in a sand and gravel aquifer
Jeff M. Markle, Robert A. Schincariol, J.H. Sass, John W. Molson
None, Soil Science Society of America Journal (70) 1281-1294
Both hydrologic and thermal transport properties play a significant role in the movement of heat through permeable sedimentary material; however, the thermal conductivity is rarely characterized in detailed spatial resolution. As part of a study of the movement of thermal plumes through a sand and gravel aquifer, we have constructed...

L.W. Currier
None, Eos, Transactions, American Geophysical Union (18) 260-261
The Chelmsford granite is quarried in and around Oak Hill, about six miles west of Lowell, Massachusetts. The granite‐area is about eight miles long and one to three miles wide, and its longer dimension has a northeast bearing which is parallel with the regional axis of foliation in the country...
