Stratigraphy, sedimentology, and petrology of neogene rocks in the Deschutes basin, central Oregon : a record of continental-margin volcanism and its influence on fluvial sedimentation in an arc-adjacent basin

Creator:

Smith, Gary Allen

Abstract:

Neogene rocks of the Deschutes basin include the middle Miocene Columbia River Basalt Group and Simtustus Formation, and late Miocene to early Pliocene Deschutes Formation. Assignment of Prineville chemical-type flows to the Grande Ronde Basalt of the Columbia River Basalt Group is based upon correlation of these lavas from their...

Beyond the paired-catchment approach : isotope tracing to illuminate stocks, flows, transit time, and scaling

Creator:

Hale, V. Cody

Abstract:

This dissertation integrates a process-based hydrological investigation with an ongoing paired-catchment study to better understand how forest harvest impacts catchment function at multiple scales. We do this by addressing fundamental questions related to the stocks, flows and transit times of water. Isotope tracers are used within a top-down catchment intercomparison...
