Insights From Layered Anisotropy Beneath Southern New England: From Ancient Tectonism to Present‐Day Mantle Flow
Autor: Yantao Luo, Maureen D. Long, Frederik Link, Paul Karabinos, Yvette D. Kuiper
Publikováno v: Geochemistry, Geophysics, Geosystems, Vol 24, Iss 12, Pp n/a-n/a (2023)
Abstract Seismic anisotropy beneath eastern North America, as expressed in shear wave splitting observations, has been attributed to plate motion‐parallel shear in the asthenosphere, resulting in fast axes aligned with the plate motion. However, de

Formation of orogenic gold deposits by progressive movement of a fault-fracture mesh through the upper crustal brittle-ductile transition zone
Autor: Miguel Tavares Nassif, Thomas Monecke, T. James Reynolds, Yvette D. Kuiper, Richard J. Goldfarb, Sandra Piazolo, Heather A. Lowers
Publikováno v: Scientific Reports, Vol 12, Iss 1, Pp 1-11 (2022)
Abstract Orogenic gold deposits are comprised of complex quartz vein arrays that form as a result of fluid flow along transcrustal fault zones in active orogenic belts. Mineral precipitation in these deposits occurs under variable pressure conditions

Detrital zircon ages and the origins of the Nashoba terrane and Merrimack belt in southeastern New England, USA
Autor: J. Christopher Hepburn, MaryEllen L. Loan, Robert Buchwaldt, Kristin J. McClary, Michael Tubrett, Yvette D. Kuiper
Publikováno v: Atlantic Geology. 57:343-396
The fault-bounded Nashoba–Putnam terrane, a metamorphosed early Paleozoic, Ganderian arc/back-arc complex in SE New England, lies between rocks of Avalonian affinity to the southeast and middle Paleozoic sedimentary rocks, interpreted as cover on G

Exploring the nature and extent of the Mesoproterozoic Picuris orogeny in Colorado, USA
Autor: Yvette D. Kuiper, Ruth F. Aronoff, Christopher G. Daniel, Madison Bzdok
The Mesoproterozoic is a controversial time within the Earth’s history, and is characterized by high temperature/pressure ratios in metamorphic rocks, a large volume of extensional plutons, very few economic mineral deposits, and possibly a slowdow

Diagenetic and Epigenetic Mineralizing Events in the Kalahari Copperbelt, Botswana: Evidence from Re-Os Sulfide Dating and U-Th-Pb Xenotime Geochronology
Autor: M. Stephen Enders, Wesley S. Hall, Holly J. Stein, Catherine Knight, Andrew R.C. Kylander-Clark, Murray W. Hitzman, Yvette D. Kuiper
Publikováno v: Economic Geology. 116:863-881
The ages of sedimentation and copper-silver mineralization in the late Meso- to Neoproterozoic Kalahari Copperbelt in Botswana, an economically significant copper province, have previously been poorly constrained within an ~600 m.y. period that spans

U-Pb detrital zircon analysis of sedimentary rocks of the southeastern New England Avalon terrane in the U.S. Appalachians: Evidence for a separate crustal block
Autor: Yvette D. Kuiper, Daniel P. Murray, Sonia Ellison, James L. Crowley
The Avalon terrane of southeastern New England is a composite terrane in which various crustal blocks may have different origins and/or tectonic histories. The northern part (west and north of Boston, Massachusetts) correlates well with Avalonian ter

New detrital zircon U-Pb ages and Lu-Hf isotopic data from metasedimentary rocks along the western boundary of the composite Avalon terrane in the southeastern New England Appalachians
Autor: Allison R. Severson, Yvette D. Kuiper, G. Nelson Eby, Hao-Yang Lee, J. Christopher Hepburn
West Avalonia is a composite terrane that rifted from the supercontinent Gondwana in the Ordovician and accreted to Laurentia during the latest Silurian to Devonian Acadian orogeny. The nature and extent of West Avalonia are well constrained in Nova

Detrital zircon populations of the eastern Laurentian margin in the Appalachians
Autor: J. Christopher Hepburn, Yvette D. Kuiper
Publikováno v: Geology. 49:233-237
Newly compiled U-Pb detrital zircon data from eight geographic domains along the eastern Laurentian margin from Newfoundland (Canada) to Alabama (United States) show a highly consistent signature along strike, with only minor local variations. The Pr
