Gold gradients and anomalies in the Pedro Dome-Cleary Summit area, Fairbanks district, Alaska
Robert B. Forbes, H.D. Pilkington, D. B. Hawkins
1968, Open-File Report 68-101
Anomalous gold values have been discovered in hydrothermally altered quartz diorite, quartz monzonite, and quartz mica schist at the head of Fox Creek; and in similarly altered quartz diorite in the Granite Creek area. Channel samples across some of these altered zones have produced anomalous gold values over widths which...

Extensive geochemical anomalies are present along the west side of the Sheep Creek Range in Lander County, Nev. Anomalous concentrations of zinc, arsenic, mercury, silver, copper, lead, and to some extent gold, molybdenum, and antimony occur in iron-rich material along fracture planes and in quartz veins in Paleozoic formations. A...

Utilization of humus-rich forest soil (mull) in geochemical exploration for gold
Gary C. Curtin, H. W. Lakin, G. J. Neuerburg, A.E. Hubert
1968, Circular 562
Distribution of gold in humus-rich forest soil (mull) reflects the known distribution of gold deposits in bedrock in the Empire district, Colorado. Gold from the bedrock is accumulated by pine and aspen trees and is concentrated in the mull by the decay of organic litter from the trees. Anomalies in...
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,...
