The positions of Laurentia and other landmasses in the Precambrian supercontinent of Rodinia are controversial. Although geological and isotopic data support an East Antarctic fit with western Laurentia, alternative reconstructions favor the juxtaposition of Australia, Siberia, or South China. New geologic, age, and isotopic data provide a positive test of the juxtaposition with East Antarctica: Neodymium isotopes of Neoproterozoic rift-margin strata are similar; hafnium isotopes of ∼1.4… Expand

Neoproterozoic sedimentary rocks track the location of the Lhasa Block during the Rodinia breakup
Abstract Cimmerian terranes in Tibet are thought to be as old as Archean or as young as Neoproterozoic or even early Paleozoic in age. However, their Precambrian history and their role in theExpand
Absence of evidence for Palaeoproterozoic eclogite-facies metamorphism in East Antarctica: no record of subduction orogenesis during Nuna development
New zircon petrochronological data from relict eclogite preserved in the Nimrod Complex indicate that high-pressure metamorphism did not occur in the Palaeoproterozoic, but instead occurred during early Palaeozoic Ross orogenesis along the active convergent margin of East Gondwana. Expand

Zircon U-Pb ages from glacial clasts in Quaternary tills of the central Transantarctic Mountains indicate the presence of Grenville-age crust along the Ross Sea margin of East Antarctica. TheExpand


Laurentia, australia, and antarctica as a late proterozoic supercontinent: constraints from isotopic mapping
The reconstruction of Laurentia, Australia, and Antarctica into a Proterozoic supercontinent is evaluated by analyzing the fit of Precambrian provinces defined by isotopic and geochronologic mapping.Expand
Paleomagnetic constraints on timing of the Neoproterozoic breakup of Rodinia and the Cambrian formation of Gondwana
Paleomagnetic data from East Gondwana (Australia, Antarctica, and India) and Laurentia are interpreted to demonstrate that the two continents were juxtaposed in the Rodinia supercontinent by 1050 Ma.Expand
