Major-oxide and trace-element geochemistry of mafic rocks in the Carboniferous Lisburne Group, Ivishak River area, northeastern Brooks Range, Alaska The Alaska Division of Geological & Geophysical Surveys, in collaboration with the University of Alaska Fairbanks, collected mafic rocks in the Ivishak River area of the northeastern Brooks Range during summer 2009 for geochemical sampling. The sampled rocks, including lava flows, sills, and limy volcaniclastic strata, crop out within the carbonate-platform succession of the Carboniferous Lisburne Group. Refer to Herriott and others (2011) for additional information regarding the geologic and geographic context of these samples, preliminary implications of the geochemical data presented here, and a summary of known mafic rock occurrences in the Arctic Alaska terrane. The analytical data tables associated with this... Tags: Analyses and Sampling, Brooks Range, Geochemical Data, Geochemistry, Igneous, All tags...

Units were mapped by interpretation of stereo pairs of approximately 1:65,000-scale false-color infrared aerial photographs taken in June and August 1978, as well as 2.5 m and 10 m resolution SPOT imagery collected in 2009 and 2010. Fieldwork was completed in 2008. Tags: Aeolian, Alaska Pipeline, Alaska, State of, Colluvial Deposits, Colluvium, All tags...

This area encompasses approximately 600 square miles in the northern foothills of the Brooks Range, and includes stratigraphic and structural elements important to understanding the oil and gas potential of Alaska's North Slope.
