This surficial-geologic map shows the distribution of unconsolidated deposits and undifferentiated bedrock in the Faith Creek area in the Circle A-4, A-5, B-4, and B-5 quadrangles. This map was prepared principally by the interpretation of 1:63,360-scale, false-color, infrared aerial photographs taken in 1979 and 1981 and is locally verified by ground observations during field work in 2007.
Geologic studies of the upper Chena River area were undertaken in 1983 as part of the Interior Mining District Evaluation Program, a series of projects designed to develop new information on known mineral districts in interior Alaska. During the three-year course of the program, geologists examined four districts that have contributed significantly to historical gold production in Alaska's Interior, Fairbanks, Livengood, Richardson, and upper Chena River.
This map illustrates potential near-surface sources of geologic materials that may be useful for construction and other purposes. Field observations indicate that each geologic unit (for example, flood-plain alluvium) has a definite composition or range of composition. Therefore, the presence of material type is interpreted from the distribution of geologic units (Newberry and others, 1996 - PDF96-16). Assignment of Unified Soil Classes (Wagner, 1957) is based on visual observation and interpretation of the likely distribution of the materials; no grain-size analyses were performed. Descriptions of unconsolidated deposits are modified from Pewe and Bel (1975a-d) and Pewe and Bell (1976). This map is generalized...
Trace element geochemical data from reanalysis of stream-sediment samples collected in 1981 from the Fairbanks mining district, Alaska
The geochemical analyses in this report result from the reanalysis of 932 archived stream-sediment pulps from the northern Fairbanks D-1, northern Fairbanks D-2, Fairbanks D-3 and southern Livengood A-1 and A-2 Quadrangles. The original geochemical data set included 1013 stream-sediment samples, (Albanese, 1982a-c).
This preliminary geologic map of the Fairbanks mining district was mapped at 1:63,360 scale. The report describes the geologic setting, structural geology, earthquake potential, economic geology and the description of bedrock units.
