Drilling and testing of well 340, Fort Wingate Army Depot, McKinley County, New Mexico
John W. Shomaker
1969, Report
The U.S. Geological Survey was requested by Fort Wingate Army Depot to designate a well location, suggest construction and testing procedures, and provide continuing technical advice with respect to the drilling of a new production well. The location was determined during a brief preliminary study of the Depot's water supply...
Land subsidence due to the application of water
Ben Elder Lofgren
David J. Varnes, George Kiersch, editor(s)
1969, Book chapter, Reviews in Engineering Geology
Loose, dry, low-density deposits that compact when they are wetted mantle extensive areas in North America, Europe, and Asia. This process, here referred to as hydrocompaction, has produced widespread subsidence of the land surface. Hydrocompaction may occur under natural overburden load or may occur only with the addition of a...
Geology and regional metamorphism of some high-grade cordierite gneisses, Front Range, Colorado
Dolores J. Gable, Paul K. Sims
1969, Book
Cordierite is common in regional metamorphic gneisses of Precambrian age in the central part of the Front Range. It occurs in discontinuous stratigraphic units that are structurally a minor component, except locally, of the thick succession of biotite gneisses that comprise the widespread Idaho Springs Formation. The rocks have mineral...
History of the Redwall Limestone of northern Arizona
Edwin D. McKee, Raymond C. Gutschick
1969, Book
Throughout most of northern Arizona the Redwall Limestone of Mississippian age is readily divisible into four lithologic units, designated in ascending order as the Whitmore Wash, Thunder Springs, Mooney Falls, and Horseshoe Mesa Members. The first and third members are thick-bedded to massive carbonate rock. The Horseshoe Mesa Member is...
Water resources data for Indiana, 1968
Water Resources Division, U.S. Geological Survey
1969, Water Data Report IN-68-1
The surface-water records for the 1968 water year for gaging stations, partial-record stations, and miscellaneous sties within the State of Indiana are given in this report. For convenience there are also included records for a few pertinent gaging stations in bordering States. Water-resources investigations of the U.S. Geological Survey include the...
Safety and survival in an earthquake
Water Resources Division, U.S. Geological Survey
1969, Report
Many earth scientists in this country and abroad are focusing their studies on the search for means of predicting impending earthquakes, but, as yet, an accurate prediction of the time and place of such an event cannot be made. From past experience, however, one can assume that earthquakes will continue...
Effects of toxicants on community metabolism in pools
Walter R. Whitworth, Thomas H. Lane
1969, Limnology and Oceanography (14) 53-58
Estimates of community metabolism of simulated natural environments were dcrivcd by diel oxygen techniques over a period of nine months. During this time, toxicants were added to some of the pools. "Natural" environmental factors and toxicants that did not affect the communities (0.02 mg/liter p,p' DDT; 0.1 mg/liter antimycin A;...

Modern coastal mangrove swamp stratigraphy and the ideal cyclothem
David W. Scholl
Edward C. Dapples, M. E. Hopkins, editor(s)
1969, Book chapter, Environments of coal deposition: Papers presented at a symposium by the coal geology division of the Geological Society of America at the annual meeting Miami Beach, Florida, 1964
The general stratigraphy of the “ideal” cyclothem of Late Paleozoic age can be recognized in a modern succession of sedimentary units underlying the coastal mangrove swamps of southwestern Florida. Because coal deposition is associated with the formation of cyclothems, this stratigraphic similarity has geologic importance with respect to coal formation.The...

Recognition and significance of pumice in marine pyroclastic rocks
Richard S. Fiske
1969, Geological Society of America Bulletin (80) 1-8
Pumice is abundant in many ancient sequences of marine pyroclastic rocks and is regarded as important evidence that contemporaneous, or nearly contemporaneous, volcanic activity was the source of at least some of the fragmental debris. The pumice in many such sequences of rocks, however, is easily overlooked, chiefly because most...

Landforms of the United States
John T. Hack
1969, Report
The United States contains a great variety of landforms which offer dramatic contrasts to a crosscountry traveler. Mountains and desert areas, tropical jungles and areas of permanently frozen subsoil, deep canyons and broad plains are examples of the Nation's varied surface. The present-day landforms the features that make up the...
Mineral layering in the Twin Lakes granodiorite, Colorado
H. G. Wilshire
Leonard H. Larsen, Martin Prinz, Vincent Manson, editor(s)
1969, GSA Memoirs 235-262
The Twin Lakes intrusion is composed mainly of coarse-grained porphyritic granodiorite, and is zoned from a felsic core to a slightly more mafic border. Steeply dipping mineral layers, typically a few inches to 5 feet thick and several tens of feet long, occur in discontinuous marginal zones as wide as...
Geologic Settings of Subsidence
Alice S. Allen
David J. Varnes, George Kiersch, editor(s)
1969, Book chapter, Reviews in Engineering Geology
This paper reviews the role of geologic processes that contribute to subsidence in order to aid those starting investigations of ground-surface subsidence. Subsidence occurs, or at least is discovered, only infrequently, and little organized information has been available. In order to assess our present state of knowledge, the author gathered...

The Cloudy Pass epizonal batholith and associated subvolcanic rocks
Fred W. Cater
1969, Book chapter, The Cloudy Pass epizonal batholith and associated subvolcanic rocks
The Cloudy Pass batholith, one of several small epizonal Tertiary batholiths in the Northern Cascade Mountains, discordantly intrudes metamorphic rocks of pre-Late Cretaceous age. The batholith is remarkable for its chilled borders, associated porphyry plugs, and intrusive breccias. The main body of the batholith consists largely of labradorite granodiorite.Part of...
Structural geology of the Quad-Wyoming-Line Creeks area, Beartooth Mountains, Montana

1969, Book chapter, Igneous and Metamorphic Geology
The Quad-Wyoming-Line Creeks area is in the northeastern part of the Beartooth Mountains of Montana. The rocks of the area consist mainly of banded migmatite, granitic gneisses, amphibolite, quartzite, and agmatite; small amounts of biotite schist and biotite gneiss, iron-silicate rocks, ultramafic rocks, mafic dikes, and felsic porphyries are also...

Photogrammetry with surface-based images
Raymond M. Batson
1969, Applied Optics (8) 1315-1322
Stereoscopic pictures returned by surface-based imaging systems can be used to reconstruct the topography of landing sites on Mars and other planets. Large surface relief with respect to distance and the large scale variation inherent in surface-based pictures produce problems in stereoscopic measurement very different from those presented by high...
