Preliminary geologic interpretation of aeromagnetic data in the Nixon Fork district, Alaska
Lennart A. Anderson, Bruce L. Reed, Gordon R. Johnson
1969, Open-File Report 69-9
An aeromagnetic map covering 480 square miles was compiled for the Nixon Fork district, which is located approximately 35 miles northeast of McGrath, Alaska. The survey was flown in search of concealed intrusive rocks which may have produced contact metamorphic deposits in limestone similar to the known lode deposits which...

Preliminary geologic interpretation of aeromagnetic data in the Yakutat district, Alaska
Gordon R. Johnson, George Plafker
1969, Open-File Report 69-134
An aeromagnetic survey covering portions of the Yakutat Feveland region in south-central Alaska was made to delineate concentrations of magnetic minerals possibly associated with heavy mineral placers in beach sands and raised beach ridges. However, the larger magnetic anomalies do not correlate with the beach placers in the surveyed area....
Gold anomalies and magnetometer profile data, Ester Dome area, Fairbanks district, Alaska
D.L. Stevens, Robert B. Forbes, D. B. Hawkins
1969, Open-File Report 69-266
Gold analysis of grab and auger samples of bedrock taken along the new Ester Dome Road reveals that this road cuts several mineralized zones characterized by anomalous concentrations of gold. The results of a magnetometer traverse along this road indicate that the negative magnetic anomalies along the traverse may be...

Results of geological and geochemical investigations in an area northwest of the Chulitna River, central Alaska Range
C.C. Hawley, A. L. Clark, M.A. Herdrick, S. H. B. Clark
1969, Circular 617
Sedimentary and volcanic rock units of Paleozoic and Mesozoic age, faults, and elongate bodies of intrusive rock, particularly serpentinites, have a dominant northeasterly trend in an area northwest of the Chulitna River between Eldridge Glacier and Bull River. The serpentinites locally contain abnormal (as much as 0.5 percent) concentrations of...

Metalliferous deposits near Granite Mountain, eastern Seward Peninsula, Alaska
Thomas P. Miller, Raymond L. Elliott
1969, Circular 614
New deposits of lead, zinc, and silver were found in a large altered zone 18 miles long and 2 to 5 miles wide near Quartz Creek west of Granite Mountain in the eastern Seward Peninsula, Alaska. New deposits of molybdenum, bismuth, and silver were found associated with a previously reported...

1969, Circular 611
An asbestos occurrence was discovered in a remote part of the Eagle quadrangle, Alaska, in the summer of 1968 during geologic reconnaissance in connection with the U.S. Geological Survey's Heavy Metals program. The exposed part of the deposit consists of large joint blocks of serpentine which are cut by closely...
