... The Marenisco-Watersmeet area in the western part of the northern peninsula of Michigan contains a greenstone and granite terrane (Puritan Quartz Monzonite) of late Archean age on the north and a gneiss terrane (gneiss at Watersmeet) on the south. A granite and gneiss belt (collectively called...

...David Schneider; Daniel Holm; Daniel Lux Abstract Biotite 40 αr/ 39 αr cooling ages from medium-pressure (500–600 MPa) rocks in the Watersmeet district, northern Michigan, suggest significant cooling–uplift and concomitant deformation during gneiss dome formation at~1755 Ma, well after the close...

... thermochronologic relationships and ages, suggesting that their boundary is not a fundamental suture between two distinct Paleoarchean terranes. Previously obtained zircon age data from the tonalitic gneiss at Watersmeet Dome in northern Michigan indicated formation at ca. 3500 Ma, whereas a granite body near...

... Sm-Nd model ages on a whole-rock sample of the gneiss at Watersmeet, Michigan, show that these rocks were added to the continental crust about 3,600 m.y. ago. These model ages are calculated by assuming that the rocks were derived from a mantle reservoir with the Sm/Nd ratio of CHUR, which...

Whereas on the one hand, a 3.18 Ga gneiss from the Granite Mountains, Wyoming, yielded identical 176 Hf/ 177 Hf ratios from both near-concordant and highly discordant zircon fractions, zircon from a gneiss from Watersmeet, Michigan, showed...

Archean ages as old as these have yet to be measured in basement gneisses in the Marshfield terrane, but these grains could have come from gneisses within the Superior Province, such as the Watersmeet Gneiss...
