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...

Geologic structure between the Murray fracture zone and the Transverse Ranges
Roland E. von Huene
1969, Marine Geology (7)
The Murray fracture has been thought to extend ashore into the Transverse Ranges of California, but a geophysical study shows no evidence of structural continuity between these features. Instead, basement morphology typical of the Murray fracture zone ends where its known magnetic and...
Geochemistry and origin of formation waters in the western Canada sedimentary basin-I. Stable isotopes of hydrogen and oxygen
B. Hitchon, I. Friedman
1969, Geochimica et Cosmochimica Acta (33) 1321-1349
Stable isotopes of hydrogen and oxygen, together with chemical analyses, were determined for 20 surface waters, 8 shallow potable formation waters, and 79 formation waters from oil fields and gas fields. The observed isotope ratios can be explained by mixing of surface water...
Anorthosite belts, continental drift, and the anorthosite event
N. Herz
1969, Science (164) 944-947
Most anorthosites lie in two principal belts when plotted on a predrift continental reconstruction. Anorthosite ages in the belts cluster around 1300 ±...
Beach lamination: Nature and origin
H.E. Clifton
1969, Marine Geology (7) 553-559
A distinctive two-fold sedimentation unit characterizes lamination in the upper swash zone of beaches. Within the unit a fine and/or a heavy mineral rich layer at the base grades upward into a coarser and/or a heavy mineral poor layer at the top. This...

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....

Analyses of samples G-1 and W-1 made between 1965-1967 have been collected and "best values" for many elements are suggested....
Saline water in southeastern New Mexico

1969, Chemical Geology (4) 341-360
Saline waters from formations of several geologic ages are being studied in a seven-county area in southeastern New Mexico and western Texas, where more than 30,000 oil and gas tests have been drilled in the past 40 years. This area of 7,500 sq. miles, which is stratigraphically complex, includes...
The isotopic composition of lead in potassium feldspars from some 1.0-b.y. old North American igneous rocks
R. E. Zartman, G.J. Wasserburg
1969, Geochimica et Cosmochimica Acta (33) 901-942
The isotopic composition of lead and the uranium, thorium and lead concentrations in potassium feldspars are determined for more than 30 1.0-b.y. old North American igneous rocks. Samples representing a broad spectrum in petrographic type and mode of occurrence were chosen; an effort was made to include only rocks having...
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...
