The origin and tectonic setting of the Mesoproterozoic (1.50–1.34 Ga) granite–rhyolite Provinces of the midcontinent region of the United States, and the coeval A-type granite plutons of the southwestern United States, have been an enigma for dec

The Borborema Province has three major subprovinces. The northern subprovince lies north of the Patos shear zone and is comprised of Paleoproterozoic cratonic basement with Archean nuclei, plus overlying Neoproterozoic supracrustal rocks and Brasilia

The Congo (CC) and the Sao Francisco (SFC) cratons were joined at about 2.05 Ga; northern parts of Palaeoproterozoic basement subsequently underwent extension at about 1 Ga, forming intracratonic basins. Neoproterozoic metasedimentary rocks in these

U–Pb geochronology of the Wolf River batholith, north-central Wisconsin: Evidence for successive magmatism between 1484Ma and 1468Ma

Autor: W. R. Van Schmus, T.J. Dewane

Publikováno v: Precambrian Research. 157:215-234

Single-grain zircon U–Pb age determinations were completed on individual phases of the Mesoproterozoic, anorogenic Wolf River batholith (WRB) of Wisconsin and the nearby Wausau syenite complex in order to (a) define the age more precisely and accur

Two Paleoproterozoic (Statherian) siliciclastic metasedimentary sequences in central Wisconsin: The end of the Penokean Orogeny and cratonic stabilization of the southern Lake Superior region

Statherian siliciclastic sedimentary rocks in the southern Lake Superior region are key to understanding the evolution and stabilization of Paleoproterozoic crust in the midcontinent. Deposited during an important period of significant crustal growth
