Preliminary geologic investigation of the Apollo 12 landing site: Part B: photometric and polarimetric properties of the lunar regolith
Several special, as well as general, photometric and polarimetric studies of the lunar regolith in the vicinity of the Apollo 12 landing site have been undertaken by means of the black-and-white photographs obtained on the geologic traverse during the second extravehicular activity (EVA) period.

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.

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 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 units. The pro

The Alaska earthquake, March 27, 1964: Lessons and conclusions
One of the greatest earthquakes of all time struck south-central Alaska on March 27, 1964. Strong motion lasted longer than for most recorded earthquakes, and more land surface was dislocated, vertically and horizontally, than by any known previous temblor. Never before were so many effects on earth processes and on the works of man available for study by scientists and engineers over so great an

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 chloride. Ho

Structural geology of the Quad-Wyoming-Line Creeks area, Beartooth Mountains, Montana
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 present. Quartzite outcrops continuously around t
