Methods and Costs of Gravel and Placer Mining in Alaska

Chester Wells Purington

1905, Bulletin 263

A reconnaissance in northern Alaska across the Rocky Mountains, along Koyukuk, John, Anaktuvuk, and Colville Rivers, and the Arctic coast to Cape Lisburne, in 1901, with notes

F. C. Schrader, W. J. Peters

1904, Professional Paper 20

Since 1898 the United States Geological Survey has been carrying on systematic topographic and geologic surveys in Alaska under an appropriation made for the investigation of the mineral resources of the Territory. This work has included not only areal surveys of regions already being developed by the miner and prospector,...

Chemical composition of igneous rocks expressed by means of diagrams, with reference to rock classification on a quantitative chemico-mineralogical basis

J. P. Iddings

1903, Professional Paper 18

The value of graphical methods for expressing relative quantities has been well established in all kinds of statistical exposition and discussion. Their use in conveying definite conceptions of relative quantities of chemical and mineral components of rocks is becoming more and more frequent, and the value of the results in...

Chemical analyses of igneous rocks published from 1884 to 1900, with a critical discussion of the character and use of analyses

H.S. Washington

1903, Professional Paper 14

In the first two or three decades of the last century, when the study of rocks as such was being differentiated from that of minerals and of rock terranes that is, when the science of petrogaphy was in its infancy little attention was paid to their chemical features. It is...

Eighteenth annual report of the United States Geological Survey to the Secretary of the Interior, 1896-1897: Part V - Mineral resources of the United States, 1896, nonmetallic products, except coal

Edward Wheeler Parker, F.H. Oliphant, Jefferson Middleton, William C. Day, Heinrich Ries, T.C. Hopkins, C.E. Siebenthal, T.W. Vaughan, Spencer Newberry, George F. Kunz, Albert C. Peale

1897, Annual Report 18-5

In the preceding volumes of Mineral Resources the annual reports on the manufacture of coke a well a those on the production of crude petroleum and natural gas were prepared by Mr. Joseph Dame Weeks, of Pittsburg, Pa. The sudden death of Mr. Weeks on December 26, 1896, necessitated the...

III.-The Work of Prof. Henry Carvill Lewis in Glacial Geology

Warren Upham

1889, Geological Magazine (6) 155-160

The recent notice of the life and work of Prof. Henry Carvill Lewis, whose lamented death occurred in Manchester, July 21st, 1888, in his thirty-fifth year, well indicates the wide range of his scientific labours. He published valuable results of investigations in astronomy, mineralogy and petrology, and especially in glacial...

Geology and mining industry of Leadville, Colorado, with atlas

Samuel Franklin Emmons

1886, Monograph 12

The present work was undertaken at the instance of the Ron. Clarence King, first Director of the United States Geological Survey, in 1879. Itwas his intention that it should form part of a series of monographs which would in time include all the important mining districts of the country, and thus furnish...

The gabbros and associated hornblende rocks occurring in the neighborhood of Baltimore, Maryland

George Huntington Williams

1886, Bulletin 28

Considerable attention has been devoted during late years to the metamorphism of igneous rocks, and it can now be regarded as placed beyond reasonable doubt that such rocks may be changed to more or less schistose masses, which often closely resemble crystallized sediments. This possibility has heretofore been largely ignored,...

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...

Preliminary Field Report of the United States Geological Survey of Colorado and New Mexico

Ferdinand Vandeveer Hayden

1869, Report

SIR : In accordance with your instructions dated Washington, April 1, 1869, I have the honor to transmit my preliminary field report of the United States geological survey of Colorado and New Mexico, conducted by me, under your direction, during the past season. A portion of your instructions is as...

Early Paleozoic composite melange terrane, central Appalachian Piedmont, Virginia and Maryland; Its origin and tectonic history

Louis Pavlides

None, Book chapter

Two distinct types of mélange deposits, distinguished by their matrix, occur within a collage of thrust slices in the Piedmont of the central Appalachians. They crop out in a northeast-trending belt that extends...

Exsolved magmatic fluid and its role in the formation of comb-layered quartz at the Cretaceous Logtung W-Mo deposit, Yukon Territory, Canada

Jacob B. Lowenstern, W. David Sinclair

None, Book chapter, The Third Hutton symposium on the origin of granites and related rocks

Comb-layered quartz is a type of unidirectional solidification texture found at the roofs of shallow silicic intrusions that are often associated spatially with Mo and W mineralisation. The texture consists of multiple layers of euhedral, prismatic quartz crystals (Type I) that have grown on subplanar aplite substrates. The layers are...
