Maps showing aeromagnetic survey and geologic interpretation of the Chignik and Sutwik Island quadrangles, Alaska Maps showing aeromagnetic survey and geologic interpretation of the Chignik and Sutwik Island quadrangles, Alaska
An aeromagnetic survey over part of the Chignik and Sutwik Island quadrangles, on the southern Alaska Peninsula, was flown in 1977 as part of the Alaska mineral resource assessment program (AMRAP). Maps at scales 1:250,000 and 1:63,360 have been released on open-file (U.s. Geological Survey, 1978a, 1978b). This report includes the aeromagnetic map superimposed on the topographic base...

The Togiak-Tikchik complex of southwestern Alaska, a replacement for the Gemuk Group: Stratigraphic nomenclature that has outlived its time The Togiak-Tikchik complex of southwestern Alaska, a replacement for the Gemuk Group: Stratigraphic nomenclature that has outlived its time
During early exploratory reconnaissance of southwestern Alaska in the 1940s and 1950s, the term "Gemuk Group" was used to name a varied assemblage of sedimentary and volcanic rocks in southwestern Alaska. Throughout the 1950s and early 1960s, the name was broadly applied in the region; yet by the end of the 1960s, it was no longer in use, and later maps assigned the rocks originally in...

Geophysical identification and geological Implications of the southern Alaska magnetic trough Geophysical identification and geological Implications of the southern Alaska magnetic trough
The southern Alaska magnetic trough (SAMT) is one of the fundamental, crustal-scale, magnetic features of Alaska. It is readily recognized on 10 km upward-continued aeromagnetic maps of the state. The arcuate SAMT ranges from 30 to 100 km wide and extends in two separate segments along the southern Alaska margin for about 1200 km onshore (from near the Alaska/Canada border at about 60...
