  • Geologic structure and exhumation accompanying Yakutat terrane collision, southern Alaska

    Creator:
    Johnston, Sarah A.
    Abstract:
    The climatic and tectonic framework of the St. Elias orogen makes it an excellent place to study the interactions between tectonic processes such as deformation and erosive processes, in particular glacial erosion. One type of link between these processes, proposed by numerical models of orogenic development, is an effect of...

  • Reconstructing northern Alaska : crustal-scale evolution of the central Brooks Range

    Creator:
    Williams, Jonathan D.
    Abstract:
    Kinematic tectonic models constrained by Airy isostatic equilibrium demonstrate the crustal-scale evolution of the Brooks Range during ocean basin closure, arc-continent collision, and exhumation of the orogen. The Bouguer gravity anomaly low that develops across the orogen is related by wavelength to the amount of shortening during collision, and by...
