The Climax Molybdenum Deposit, Colorado

Description: From abstract: The largest single metal-mining operation in the history of mining in Colorado has been developed at Climax, as a result of the increased use of molybdenum in the steel and other industries. Production of molybdenum at Climax was notable for a short period during the World War; it ceased from April 1919 to August 1924 but since then has shown a steady increase. In 1930 from 1,000 to 1,200 tons of ore was milled daily, using only one unit of the 2,000-ton mill. The mine has a rese… more

Geology and Ore Deposits of the Takilma-Waldo District, Oregon: Including the Blue Creek District

Description: From Abstract: Two areas and their included mineral deposits, situated in Josephine County, southwestern Oregon, are described in this report. They lie within the Klamath Mountains, a region which is made up for the most part of rugged ridges trending in various directions but which, when viewed from higher summits, resembles a dissected plateau and is known as the Klamath peneplain. Rocks of both igneous and sedimentary origin are abundant in the districts described. The marine sedimentary roc… more

The Girdwood District, Alaska

Description: From abstract: The Girdwood district has been known for about 35 years to contain placer gold, but the source of the gold in veins was not discovered until about 1909. When the Alaska Railroad was completed through Girdwood it was hoped that the improved transportation facilities would enable the lode mines to operate at a profit and also to furnish tonnage to the railroad. Production from the quartz veins, however, has been negligible, although one placer mine has been operating steadily for s… more

The Larger Corn Stalk-Borer

Description: Revised edition. This report discusses a pale, dark-spotted caterpillar known as the larger cornstalk-borer which bores into and weakens cornstalks. "Only corn is injured seriously by this insect; some of the larger grasses are food plants, and sugar cane sometimes is damaged slightly. There are two generations in a season. As the second generation passes the winter in the corn roots, if the roots are destroyed or plowed, the pest will be largely subdued. The injury is worst where corn follows … more

Lode Deposits of Eureka and Vicinity, Kantishna District, Alaska

Description: From abstract: The Kantishna mining district is about 90 miles west of McKinley Park station on the Alaska Railroad. The part of the district covered by this report comprises an area of about 72 square miles in the form of a strip 6 miles wide and 13 miles long. The bedrock is mainly a metamorphic series of rocks which within the area has been differentiated into a quartz-muscovite schist and a calcareous faces that ranges from limestone to chlorite schist. A few small dikes of quartz porphyry … more

Lode Deposits of the Fairbanks District, Alaska

Description: From abstract: To help the mining industry of Alaska and to assist in the development of the mineral resources of the Territory have been the prime motives of the Geological Survey's investigations in Alaska during the past 35 years, in which nearly one half of the Territory has been covered by its reconnaissance and exploratory surveys. It was natural, therefore, that the Alaska Railroad, when it undertook intensive consideration of the problem of finding tonnage that would increase its revenu… more

Mineral Deposits Near the West Fork of the Chulitna River Alaska

Description: From abstract: The area in the vicinity of the West Fork of the Chulitna River, Alaska, one of those examined in 1931 in connection with the study of mineral resources in districts tributary to the Alaska Railroad, contains numerous prospects but, as yet, no productive mines. Its placer deposits are negligible but some of its lodes may prove valuable for gold and silver and perhaps also for copper and arsenic.

Miocene Foraminifera of the Coastal Plain of the Eastern United States

Description: From introduction: In the following report the species of Foraminifera found in the Miocene of the Coastal Plain region of the eastern United States from Florida to Maryland are described and recorded. Numerous papers have been published on this region, some of which, however, are largely lists. Where the original material on which a paper was based has not been available for the present study, the records have been omitted, as it is very difficult to place the species in their proper position … more

The Mount Eielson District Alaska

Description: From abstract: The Mount Eielson district lies in south-central Alaska, on the north side of the Alaska Range, about 30 miles east of Mount McKinley. The most widely distributed rocks of the district include a thick series of thin-bedded limestone, calcareous shale, and graywacke of Paleozoic, probably Devonian, age. These sediments are cut by a mass of granodiorite which forms most of Mount Eielson and which was intruded probably in late Mesozoic time. The intrusive has sent a multitude of dik… more

Past Placer-Gold Production from Alaska

Description: "To the end of 1930 Alaska, according to the records of the Geological Survey, had produced placer gold to the value of $258,962,000 from mines widely scattered throughout its length and breadth. The distribution of the placers from which the gold was recovered has been stated in more or less detail in the annual summaries published by the Geological Survey on the mineral industry of Alaska and also in its more complete reports on many of the individual mining districts. Although these summarie… more

Progress of Surveys in the Anthracite Ridge District Alaska

Description: From abstract: Anthracite Ridge is in south-central Alaska, on the north side of the Matanuska River Valley, about 200 miles north of Seward, the coastal terminus of the Alaska Railroad. The specific object of the investigations in this field during the summer of 1931 was to collect information regarding the character and extent of the anthracite deposits. These studies were carried on in connection with similar intensive studies of deposits of other kinds of minerals throughout the country tri… more
