Oceanic Pb-isotopic sources of Proterozoic and Paleozoic volcanogenic massive sulfide deposits on Prince of Wales Island and vicinity, southeastern Alaska Oceanic Pb-isotopic sources of Proterozoic and Paleozoic volcanogenic massive sulfide deposits on Prince of Wales Island and vicinity, southeastern Alaska
Volcanogenic massive sulfide (VMS) deposits on Prince of Wales Island and vicinity in southeastern Alaska are associated with Late Proterozoic through Cambrian volcanosedimentary rocks of the Wales Group and with Ordovician through Early Silurian felsic volcanic rocks of the Moira Sound unit (new informal name). The massive sulfide deposits in the Wales Group include the Big Harbor...

Studies by the U.S. Geological Survey in Alaska, 2004 Studies by the U.S. Geological Survey in Alaska, 2004
The collection of six papers that follow continues the series of U.S. Geological Survey (USGS) investigative reports in Alaska under the broad umbrella of the geologic sciences. This series represents new and sometimes-preliminary findings that are of interest to Earth scientists in academia, government, and industry; to land and resource managers; and to the general public. The reports...

26 km of offset on the Lake Clark fault since late Eocene time 26 km of offset on the Lake Clark fault since late Eocene time
Aeromagnetic data over the Lake Clark Fault reveal a north-trending band of magnetic anomalies that are right-laterally offset about 26 km across the fault. The magnetic anomalies correlate spatially with a belt of dated 34-39-Ma granitic plutons. Thus, the Lake Clark Fault has had ~26 km of right-lateral offset in the past 34-39 Ma. The Castle Mountain Fault, which lies along the strike...

Magnetic Properties of Quaternary Deposits, Kenai Peninsula, Alaska -- Implications for Aeromagnetic Anomalies of Upper Cook Inlet Magnetic Properties of Quaternary Deposits, Kenai Peninsula, Alaska -- Implications for Aeromagnetic Anomalies of Upper Cook Inlet
We measured magnetic susceptibilities of exposed Quaternary deposits on several beach cliffs and river banks on the Kenai Peninsula near Soldotna, Alaska. Data, descriptions, and photos from nine sites are included in this report. The mean susceptibility for Quaternary materials in this region is approximately 2.5 x 10-3 SI units. This is sufficiently magnetic to produce subtle...

Emplacement, rapid burial, and exhumation of 90-Ma plutons in southeastern Alaska Emplacement, rapid burial, and exhumation of 90-Ma plutons in southeastern Alaska
In southeastern Alaska, granodiorite-tonalite plutons of the Admiralty-Revillagigedo belt intruded the Jurassic-Cretaceous Gravina belt along the eastern side of the Alexander terrane around 90 Ma. These plutons postdate some deformation related to a major contractional event between the previously amalgamated Wrangellia and Alexander terranes and the previously accreted terranes of the...

Changes in crustal seismic deformation rates associated with the 1964 Great Alaska earthquake Changes in crustal seismic deformation rates associated with the 1964 Great Alaska earthquake
We calculated seismic moment rates from crustal earthquake information for the upper Cook Inlet region, including Anchorage, Alaska, for the 30 yr prior to and 36 yr following the 1964 Great Alaska earthquake. Our results suggest over a factor of 1000 decrease in seismic moment rate (in units of dyne centimeters per year) following the 1964 mainshock. We used geologic information on...
