Location and accuracy The Marguerite Creek placer gold mine is in upper Marguerite Creek, about 2 miles east northeast of Jumbo Dome. Most of the mining has been near the head of the creek, but some placer activity may have extended for some distance downstream. The map site is in sec. 13, T. 11 S., R. 6 W., of the Fairbanks Meridian. This is location 56 of Clark and Cobb (1972).

Geologic setting

Geologic description

Most of Marguerite Creek drains an area underlain by Eocene to Miocene, poorly consolidated, pebbly sandstone, claystone and subbituminous coal. These strata pinch out northward and are overlapped unconformably by Tertiary Nenana Gravel (Wilson and others, 1998). Parts of Margurite Creek flow over inliers of Keevy Peak Formation, and a Pliocene hornblende dacite plug centered on Jumbo Dome controls the arcuate shape of the creek. The probable source of the placer gold in Margurite Creek are Tertiary paleoplacers in the Nenana Gravel.
