Cu‐Isotope Evidence for Subduction Modification of Lithospheric Mantle
Autor: Pamela D. Kempton, Ryan Mathur, Russell S. Harmon, Aaron Bell, Jochen Hoefs, Barry Shaulis
Publikováno v: Geochemistry, Geophysics, Geosystems, Vol 23, Iss 8, Pp n/a-n/a (2022)
Abstract Ultramafic xenoliths from southeastern Arizona, USA, provide evidence for Cu‐isotope heterogeneity in the lithospheric mantle. We report new data on Type I (Cr‐, Mg‐rich) peridotites, but also the first Cu‐isotope data for Fe‐Ti‐

Detrital zircon geothermochronology reveals pre-Alleghanian exhumation of regional Mississippian sediment sources in the southern Appalachian Valley and Ridge Province
Autor: Barry Shaulis, Derek L. Spurgeon, William T. Jackson, Matthew P. McKay, Adelie Ionescu
Publikováno v: Geosphere. 17:1840-1860
The Black Warrior foreland basin records sedimentation associated with the development of intersecting Ouachita and Alleghanian thrust belts along the southern margin of Laurentia. Mississippian–Pennsylvanian units in the Black Warrior basin are in

Late Cretaceous sediment provenance in the eastern Gulf Coastal Plain (U.S.A.) based on detrital-zircon U-Pb ages and Th/U values
Autor: Barry Shaulis, Matthew P. McKay, Adelie Ionescu, Donald A. Beebe, William T. Jackson, Carolyn Mullins, David L. Barbeau
Publikováno v: Journal of Sedimentary Research. 91:1025-1039
Detrital-zircon U-Pb geochronology documents a regional- to continental-scale drainage reorganization along the eastern Gulf Coastal Plain (USA) from the Late Cretaceous (Cenomanian) to the Paleocene–Eocene. We present detrital-zircon U-Pb ages and

Metasomatic control of hydrogen contents in the layered cratonic mantle lithosphere sampled by Lac de Gras xenoliths in the central Slave craton, Canada
Autor: Alan D. Brandon, Trevor G. Graff, William L. Griffin, Richard V. Morris, Lillian A. Schaffer, Barry Shaulis, Suzanne Y. O'Reilly, David G. Agresti, D. Graham Pearson, McKensie L. Kilgore, Anne H. Peslier, Kelsey Gangi
Publikováno v: Geochimica et Cosmochimica Acta. 286:29-53
Whether hydrogen incorporated in nominally anhydrous mantle minerals plays a role in the strength and longevity of the thick cratonic lithosphere is a matter of debate. In particular, the percolation of hydrogen-bearing melts and fluids could potenti
