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
Lawrence C. Rowan
Leonard H. Larsen, Martin Prinz, Vincent Manson, editor(s)
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...

A purple-colored 1M mica clay from Silverton, Colorado
Pei-Lin Tien
1969, Clays and Clay Minerals (17) 245-249
A purple-colored clay of 1M mica polymorph in association with lead-zinc ore was collected from an abandoned mine dump near Silverton, Colorado. Electron micrographs show that the crystallites of the clay are less than 2µ in size and have poorly developed hexagonal outlines. Differential thermal and i.r. absorption analyses indicate...
Rapid determination of filterable residue in natural waters
Herbert E. Allen, Charles W. Bacon
1969, Journal - American Water Works Association (61) 355-356
The most widely used procedures for determining filterable residue (total dissolved solids) in water are macromethods given in Standard Methods. Although macromethods give good results, they require large amounts of water and long drying times. This report describes a microtechnique for determining filterable residue that requires only 0.05...
Rearing of sea lamprey, Petromyzon marinus, embryos in distilled water
George W. Piavis, John H. Howell
1969, Copeia (1969) 204-205
Most embryological studies of lampreys in the Great Lakes have been conducted with filtered water from Lake Huron. Although this water was entirely satisfactory for the earlier work, the present need for knowledge of the effects of various compounds on embryological development requires that the initial medium be sterile....
Surface area of vermiculite with nitrogen and carbon dioxide as adsorbates
Josephus Thomas Jr., Bruce F. Bohor
1969, Clays and Clay Minerals (17) 205-209
Surface-area studies were made on several homoionic vermiculites with both nitrogen and carbon dioxide as adsorbates. These studies show that only very slight penetration occurs between individual vermiculite platelets. This is in contrast to an earlier investigation of montmorillonite where it was found that the degree of penetration between layers...

Pyrolysis of humic and fulvic acids
R.L. Wershaw, G.E. Bohner Jr.
1969, Geochimica et Cosmochimica Acta (33) 757-762
Pyrolysis of humic and fulvic acids isolated from a North Carolina soil yields a variety of aromatic, heterocyclic and straight chain organ compounds. The pyrolysis products identified by gas chromatography and mass spectrometry indicate that humic and fulvic acids have aromatic and polysaccharide...
Loss of uranium from crystallized silicic volcanic rocks
J.N. Rosholt, D. C. Noble
1969, Earth and Planetary Science Letters (6) 268-270
Dense primarily crystallized silicic groundmass material from two welded ash-flow units and one lava flow of Tertiary age from the Western United States contain only 20 to 60 percent of the uranium present in nonhydrated glass from the rock units. These differences reflect...
