Description
In July and August of 2016, the Alaska Division of Geological & Geophysical Surveys (DGGS) conducted a field study in the Jarvis Creek coal field to better characterize these coal deposits. The Jarvis Creek Coal field is located on the north side of the Alaska Range in the Mt. Hayes C-4 quadrangle. It represents the eastern-most coal field in the east-west trending Nenana Coal Province. Located approximately 10 miles southeast of Donnelly Dome, it is bounded on the west by the Delta River, on the east by Jarvis Creek and on the south by Ruby Creek. The field is three to six miles east of the Richardson Highway and is approximately 16 square miles in area. Coal-bearing outcrops of the lower, middle, and upper units were examined in three locations in the Jarvis Creek coalfield. These locations include: 1) north of Ruby Creek, 2) the end of Coal Mine Road near the old Ober Creek mine site, and 3) near Sargent Creek in the northern part of the field. All coal samples were collected as channel samples. Eighteen samples were collected from six stations. This Preliminary Interpretive Report presents results from coal quality (proximate and ultimate analysis), Rock-Eval, hydrous pyrolysis, vitrinite reflectance, and kerogen microscopy analyses. Users can access the complete report and digital data from the DGGS website: http://doi.org/10.14509/30064.
