The article discusses the analysis of geochemical samples from the Geological Survey and Bureau of Mines (USBM) by the Alaska Division of Geological & Geophysical Surveys (DGGS). Topics included are the evaluation of Strategic and Critical Minerals (SCM) content of central Alaska Ray River watershed specimen, the documentation of location coordinates and pulp preparation methodology, and the analysis of rare earth and ore elements by ALS Minerals Laboratories.

In 2005 the Alaska Division of Geological & Geophysical Surveys initiated a multi-year geologic field study focused on a corridor centered along the Alaska Highway between Delta Junction and the Canada border. The purpose of this project is to provide geologic information relevant to a proposed Alaska-Canada natural gas pipeline and other future development in the corridor. Identification of active faults and characterization of seismic hazards were included in the project. During the 2006 and 2007 field seasons, lineaments and geologic features indicative of possible youthful surface faulting in or near the western half of the corridor between Delta Junction and Dot Lake were identified and evaluated. Four of the...

The article focuses on the Airborne Geophysical/Geological Mineral Inventory (AGGMI) program of the Division of Geological & Geophysical Surveys (DGGS) of the Alaska Department of Natural Resources in the Moran area. The work reportedly involves geological mapping of the area to encourage renewed exploration for mineral deposits. The project is expected to assist in balancing resource and infrastructure development with land-management strategies.

The Dot "T" Johnson and Cathedral Rapids faults represent the eastern part of the Northern Foothills fold and thrust belt, and are geomorphically well expressed by triangular facets, anticlinal warps, and scarps in Quaternary deposits between Granite Mountain and Tok River. Previous paleoseismic trenching indicates that these faults have both generated at least one and possibly multiple Holocene earthquakes. We created various LiDAR-derived base maps along the Dot "T" Johnson fault to assess the relative utility of each product in assessing the location of tectonic features. Our results indicate that the most robust interpretations require combined observations from multiple products including hillshade, slope,...
