Preliminary geologic investigation of the Apollo 12 landing site: Part A: Geology of the Apollo 12 Landing Site Preliminary geologic investigation of the Apollo 12 landing site: Part A: Geology of the Apollo 12 Landing Site
This report provides a preliminary description of the geologic setting of the lunar samples returned fromt he Apollo 12 mission. A more complete interpretation of the geology of the site will be prepared after thorough analysis of the data.

Interstitial water studies on small core samples, Deep Sea Drilling Project, Leg 5 Interstitial water studies on small core samples, Deep Sea Drilling Project, Leg 5
Leg 5 samples fall into two categories with respect to interstitial water composition: 1) rapidly deposited terrigenous or appreciably terrigenous deposits, such as in Hole 35 (western Escanaba trough, off Cape Mendocino, California); and, 2) slowly deposited pelagic clays and biogenic muds and oozes. Interstitial waters in the former show modest to slight variations in chloride and...

Effects of the earthquake of March 27, 1964, on the Alaska Railroad Effects of the earthquake of March 27, 1964, on the Alaska Railroad
In the 1964 Alaska earthquake, the federally owned Alaska Railroad sustained damage of more than $35 million: 54 percent of the cost for port facilities; 25 percent, roadbed and track; 9 percent, buildings and utilities; 7 percent, bridges and culverts; and 5 percent, landslide removal. Principal causes of damage were: (1) landslides, landslide-generated waves, and seismic sea waves that...

Bibliography of the lunar surface Bibliography of the lunar surface
The term "surface" in this bibliography is defined to include landforms and surface materials and the nature of, and processes responsible for, their physical characteristics. References are divided into two listings: (1) Surface features and materials; and (2) Telescopic observations. The former is accompanied by a subject index, the latter by a locality index.

A computer program to trace seismic ray distribution in complex two-dimensional geological models A computer program to trace seismic ray distribution in complex two-dimensional geological models
A computer program has been developed to trace seismic rays and their amplitudes and energies through complex two-dimensional geological models, for which boundaries between elastic units are defined by a series of digitized X-, Y-coordinate values. Input data for the program includes problem identification, control parameters, model coordinates and elastic parameter for the elastic...

Micromineralogy of silver-bearing sphalerite from Flat River, Missouri Micromineralogy of silver-bearing sphalerite from Flat River, Missouri
Detailed mineralogical and chemical study of sphalerite-rich lead ores from Flat River, Mo., confirms the presence of anomalous amounts of silver in the sphalerite. Although silver is closely associated with chlorine and no silver sulfide minerals were identified, geochemical considerations indicate the silver may be in the form of discrete submicron-size grains of sulfide rather than...
