Geology of the Gore Canyon-Kremmling area, Grand County, Colorado
C.S. Venable Barclay
1968, Open-File Report 68-3
The Gore Canyon-Kremmling area is in the southwestern portion of the Kremmling 15-minute quadrangle, Colorado. Precambrian rocks are biotite gneiss, the Boulder Creek Granodiorite, granophyre dikes, and quartz veins. The Boulder Creek intrudes the biotite gneiss, and both of these units are cut by north-northwest-trending granophyre dikes and quartz veins....

Application of dislocation theory to analysis of vertical displacements at the ground surface caused by the Duryea event
G.E. Brethauer
1968, Open-File Report 68-20
Dislocation theory is used in an analysis that explains measured vertical displacements across a fault near the Duryea underground nuclear explosion. The difference between the measured vertical displacement and the theoretically predicted vertical displacement caused by cavity formation is termed the residual vertical displacement. The residual vertical displacement is, therefore,...

Dispersive multispectral scanning; a feasibility study
J. Braithwaite
1968, Open-File Report 68-19
Optical-mechanical line scanners can be used from aircraft and satellites to obtain strip maps of the surface over which the vehicle passes. The feasibility of combining wavelength dispersing techniques with such scanning techniques has been studied. This combination makes it possible to obtain spectral and spatial information simultaneously. Appropriate data...
