The Yellow Dog peridotite and a possible buried igneous complex of Lower Keweenawan Age in the northern peninsula of Michigan The Yellow Dog peridotite and a possible buried igneous complex of Lower Keweenawan Age in the northern peninsula of Michigan
Partly serpentinized peridotite of early Keweenawan age crops out in two places along a 20-km-long zone of positive aeromagnetic anomalies in northern Marquette County, Michigan. Most of the area is mantled by Pleistocene drift and the bedrock is not exposed. Petrographic and electron microprobe studies show that the peridotite was originally a plagioclase lherzolite containing 40-50%...

Phosphorite and other apatite-bearing sedimentary rocks in the Precambrian of northern Michigan Phosphorite and other apatite-bearing sedimentary rocks in the Precambrian of northern Michigan
Phosphatic pebbles are widespread in basal units of the Marquette Range Supergroup (Precambrian X) in the central part of the Upper Peninsula of Michigan. At one locality, a conglomeratic bed about 15 m thick averages about 15 percent P2O5, and many thinner beds are of comparable grade. This occurrence is believed to be the richest sedimentary phosphate deposit known in the Precambrian...
