...RALPH TUCK Abstract The extensive gold-bearing gravel deposits in the Fairbanks district are covered with a muck-silt overburden varying from a few feet to over 200 feet thick. This overburden is economically important as (1) Its thickness is often a limiting factor in determining whether...

Bedrock gravels of stream valleys and coastal plains are buried under thick silt deposits, usually called “muck...

...T. A. Fraser; C. R. Burn Abstract Organic-rich "muck" deposits, which blanket auriferous gravels in the Klondike area, Yukon Territory, comprise two principal stratigraphic units: ( i ) a silty Late Pleistocene deposit, and ( ii ) Holocene organics lying unconformably on the silt. The deposits...
