ULFEM time series analysis package ULFEM time series analysis package
This manual describes how to use the Ultra-Low-Frequency ElectroMagnetic (ULFEM) software package. Casual users can read the quick-start guide and will probably not need any more information than this. For users who may wish to modify the code, we provide further description of the routines.

The Cannery Formation: Devonian to Early Permian arc-marginal deposits within the Alexander Terrane, southeastern Alaska The Cannery Formation: Devonian to Early Permian arc-marginal deposits within the Alexander Terrane, southeastern Alaska
The Cannery Formation consists of green, red, and gray ribbon chert, siliceous siltstone, graywacke-chert turbidites, and volcaniclastic sandstone. Because it contains early Permian fossils at and near its type area in Cannery Cove, on Admiralty Island in southeastern Alaska, the formation was originally defined as a Permian stratigraphic unit. Similar rocks exposed in Windfall Harbor on...

Fossil locations and data for the Taylor Mountains, and parts of the Bethel, Goodnews, and Dillingham quadrangles, southwestern Alaska Fossil locations and data for the Taylor Mountains, and parts of the Bethel, Goodnews, and Dillingham quadrangles, southwestern Alaska
Information about fossils collected by U.S. Geological Survey, State of Alaska, academic, and industry geologists that have been reported in literature or archived in reports from the former U.S. Geological Survey Branch of Paleontology and Stratigraphy are compiled on a plate and table in this report to provide comprehensive paleontologic age data for the Taylor Mountains quadrangle...

Geochemical and sulfur-isotopic signatures of volcanogenic massive sulfide deposits on Prince of Wales Island and vicinity, southeastern Alaska Geochemical and sulfur-isotopic signatures of volcanogenic massive sulfide deposits on Prince of Wales Island and vicinity, southeastern Alaska
Stratabound volcanogenic massive sulfide (VMS) deposits on Prince of Wales Island and vicinity, southeastern Alaska, occur in two volcanosedimentary sequences of Late Proterozoic through Cambrian and of Ordovician through Early Silurian age. This study presents geochemical data on sulfide-rich samples, in situ laser-ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) of...
