Bibliography of selected references on the geology of the Livengood Quadrangle, east-central Alaska

“…The work of many geologists, too many to cite, in the last 100 years has contributed to the preparation of this map. Please consult Wheeler and Weber, 1988 for a comprehensive listing of references pertaining to the Livengood quadrangle prior to 1988. The best early summary of the geology of the Yukon-Tanana Upland is in Mertie, 1937.…”

Qa Alluvium (Holocene) Silt, sand, and granule-to boulder-sized material having minor amounts of organic debris, gray, yellowish-gray to brown, well -sorted and -stratified. Alluvium shows fining-upward cycles. Underlies active stream beds or floodplain, locally frozen in silty channels; includes placer-mine tailings on sections of Quail, Troublesome, Ophir, and Nome Creeks, streams in Livengood village area, and southeast of Chatanika River in Fairbanks mining district; 0.3 m to approximately 15 m thick.Qg Reworked creek gravels in placer mining areas (Holocene) Placer-mine tailings derived from buried stream gravels worked for gold by methods of pick and shovel, mechanized surface, underground drifting, or dredging methods; shown, as map scale permits, on Fairbanks and Livengood Creeks, elsewhere included in Qa. Commonly less than 9 m thick.Qab Abandoned or inactive flood plain deposits (Holocene) Silt, sand, granule-to pebblesize gray gravel, and organic material. Abandoned stream channels 0.6 to 4.5 m topographically higher than active channels of Qa, elsewhere flat to hummocky and many bogs. Includes small alluvial fans, deposited by minor side streams, and intermixed alluvial sediments and very silty natural stream levees from cyclical flooding of Minto Flats.Commonly frozen. As thick as 30 m. QdSand dune deposits (Holocene) Sand, moderate yellowish-brown, well-sorted, eolian. Grains 65 to 85 percent quartz, yellowish-white, clear to opaque, angular to round; dark gray to black rock fragments, chert, mica, traces of feldspar and light-colored rock fragments. Isolated dunes mostly covered by eolian silt and stabilized by vegetation. As thick as 9 m. QsSwamp deposits (Holocene) Humus, peat, and silt in poorly-drained areas having abundant stagnant water; generally frozen below a depth of about a meter; some small swampy areas included in units Qa, Qab, and Qsu. As thick as tens of meters. QafAlluvial fan deposits (Holocene) Sand, gravel, and boulders, gray to brown, poorly-to wellsorted and stratified, coarse-grained, rounded to angular; clasts locally-derived and deposited under high-energy conditions below major decrease in slope. Locally covered by reworked silt and small amount of vegetation. Thickness varies greatly; only largest alluvial fans shown on map. Qsu Silt, undifferentiated, contains reworked loess, swamp and organic-rich deposits (Holocene) Silt, pale yellowish brown, largely eolian, and in part, locally retransported to lower slopes and valley bottoms by alluvial and solifluctional processes. Local brown to grayish black organic rich layers, masses, and disseminated debris. Poorly drained and frozen as abundant horizontal and vertical sheets, wedges, and irregular masses of ground ice. Thickness ranges from 1 to 61 m. QIC Loess and colluvium Including minor upland alluvium (Holocene) Unsorted mixture of local bedrock fragments and loess, light-gray to brown, angular or subrounded; partially frozen, fairly well-drained, locally occurs as mixture of reworked loess and colluvium in drainage chan...
