Placer gold occurrences in Alaska
Edward Huntington Cobb
1964, Mineral Investigations Resource Map 38
The following references give data on localities of placer gold by quadrangle and are keyed by number within each quadrangle to locations shown on map. The quadrangle boundaries and names used on the map are those selected by the U. S. Geological Survey for topographic mapping in Alaska on a...
Potassium-argon and lead-alpha ages of plutonic rocks, Bokan Mountain area, Alaska
M. A. Lanphere, E.M. MacKevett Jr., T. W. Stern
1964, Science (145) 705-707
Most of the granitic rocks in the Bokan Mountain area, southeastern Alaska, are early Paleozoic (probably Ordovician) judged by potassium-argon and lead-alpha age measurements. The Bokan Mountain Granite, the youngest intrusive unit in the area, belongs to a Mesozoic plutonic episode. These age measurements are the first direct evidence for...
Pre-tertiary orogenic and plutonic intrusive activity in central and northeastern Oregon
T. P. Thayer, C. E. Brown
1964, Geological Society of America Bulletin (75) 1255-1261
Pre-Tertiary rocks of the Blue Mountain region of central and northeastern Oregon comprise three major sedimentary and volcanic sequences and two distinct intrusive magma series. The ages of the sedimentary-volcanic sequences are Paleozoic, Late Triassic-Late Jurassic, and middle Cretaceous (Albian to Cenomanian), respectively. The earlier intrusive magma series ranges in composition from peridotite to albite granite and was emplaced during the major...
Magnetic disturbances preceding the 1964 Alaska earthquake
George W. Moore
1964, Nature (203) 508-509
THROUGH a fortunate circumstance, a recording magnetometer was operating in the city of Kodiak, 30 km north-west of the surface trace of a fault zone along which movement occurred at the time when the earthquake occurred in Alaska on March 27, 1964. Fortunately, too, the instrument...
