  Geometry and Kinematics of Bump-Type Fault-Bend Folding
  Jiajun ChenDengfa HeJohn SuppeFanglei Tian

  A quantitative kinematic model of bump-type fault-bend folding offers a robust framework for dating the folding of detachment layers, as well as reconstructing the slips and orientations of thrust sheets.

  A Laurentian Cratonic Reference From the Distal Proterozoic Basement of Western Newfoundland Using Tandem in Situ and Isotope Dilution U-pb Zircon and Titanite Geochronology
  Eben B. HodginFrancis A. MacdonaldJames L. CrowleyMark D. Schmitz

  The Humber Margin of Newfoundland preserves the most distal exposures of Proterozoic basement in northeastern Laurentia. Age uncertainty has permitted a range of hypotheses for its origin and links to...

  Provenance of the Newfoundland Appalachian Foreland Basins
  Shawna E. WhiteJohn W.F. WaldronGreg R. DunningS. Andrew Dufrane

  The tectonic history of the Appalachian orogen is recorded in the adjacent foreland. Offshore seismic data suggest that an initial, Middle Ordovician foreland basin was filled by sources in Newfoundland,...

  Bridging the Gap Between the Foreland and Hinterland II: Geochronology and Tectonic Setting of Ordovician Magmatism and Basin Formation on the Laurentian Margin of New England and Newfoundland
  Francis A. MacdonaldPaul M. KarabinosJames L. CrowleyEben B. HodginPeter W. CrockfordJohn W. Delano

  Ordovician strata of the Mohawk Valley and Taconic allochthon of New York and the Humber margin of Newfoundland record multiple magmatic and basin-forming episodes associated with the Taconic orogeny. Here...

  Rapid Transition From the Salinic to Acadian Orogenic Cycles in the Northern Appalachian Orogen: Evidence From Northern New Brunswick, Canada
  Reginald A. WilsonCees R. van StaalSandra L. Kamo

  Geochronological data from volcanic rocks aid in reconstructing the Silurian–Devonian evolution of the northern Appalachians of New Brunswick in the context of Salinic (Silurian) and Acadian (Devonian) orogenesis. Late Silurian...
