Greens Creek Uranium Occurrence, Marquette County, Michigan

From abstract: Metatorbernite and bassetite are present in altered carbonaceous and quartzose slate of probable upper Huronian age. The slate is part of a small inlier of Huronian rocks between the Gwinn iron district to the southeast and the Marquette iron district to the northwest, Marquette County, Mich. Samples taken from a shallow trench, which was dug in the area of highest radioactivity, contained as much as 0.68 percent uranium. A 4-foot channel sample of the slate contained 0.036 percent uranium.

Geology and Monazite Content of the Goodrich Quartzite, Palmer Area, Marquette County, Michigan (open access)

Geology and Monazite Content of the Goodrich Quartzite, Palmer Area, Marquette County, Michigan

From abstract: The Palmer area, which is on the south limb of the Marquette synclinorium, consists of a down-faulted block of pre-Cambrian sedimentary rocks about 4 miles long and three-quarters of a mile wide. The block is composed mainly of middle Huronian Ajibik quartzite and Negaunee iron-formation and upper Huronian Goodrich quartzite,. Monazite occurs in the Goodrich quartzite as rounded detrital grains concentrated mainly in the matrix of quartz pebble conglomerate which is interbedded with coarse-grained quartzite.
