Accretion tectonics and crustal structure in Alaska
P.J. Coney, D. L. Jones
1985, Tectonophysics (119) 265-283
The entire width of the North American Cordillera in Alaska is made up of "suspect terranes". Pre-Late Cretaceous paleogeography is poorly constrained and the ultimate origins of the many fragments which make up the state are unclear. The Prince William and Chugach terranes accreted since Late Cretaceous time and represent...
Crystalline gold in soil and the problem of supergene nugget formation: Freezing and exclusion as genetic mechanisms
J.R. Watterson
1985, Precambrian Research (30) 321-335
Many of the world's richest gold placer deposits now occur in cold regions despite differences in their climatic history. It therefore seems possible that there may be some fundamental connection between freezing climates and the local chemical behavior of gold in the weathering cycle. This hypothesis, along with the problematical...
Quaternary sedimentation of the Alaskan Beaufort shelf: Influence of regional tectonics, fluctuating sea levels, and glacial sediment sources
David A. Dinter
1985, Tectonophysics (114) 133-161
The offshore stratigraphy of the Quaternary Gubik Formation of Arctic Alaska has been studied on high-resolution seismic profiles with a maximum sub-seafloor penetration of about 100 m. In general, marine transgressive subunits of the Gubik Formation are wedge-shaped on the shelf, thickening slightly seaward to the shelf break, beyond which...
The United States Geological Survey in Alaska: Accomplishments during 1983
Susan B. Bartsch-Winkler, Katherine M. Reed, editor(s)
1985, Circular 945
This circular contains short reports about many of the geologic studies carried out in Alaska by the U.S. Geological Survey and cooperating agencies during 1983. The topics cover a wide range in scientific and economic interest....
