Granitic Rocks From 3 Deep Drill-Holes, Illinois, Charles J. Vitaliano, George R. Mccormick, Peter Dahl, Yoram Eckstein

Peter Dahl

A medium- and coarse-grained granite has been encountered in the lower 914 m of deep drill-holes in northwestern Illinois. The mineralogy and chemistry of both types of granite suggest they are anorogenic A-type granites after the definition of Loiselle and Wones (1979). The major oxide composition for both types is nearly identical. Trace element data (Rb, Y, Th) indicate the medium-grained granite crystallized from a more evolved melt than did the coarse-grained granite. Trace element data (Y, Th, Ba, Sr) for the coarsegrained granite show it to be slightly zoned from the bottom upward to the contact with the medium-grained …

Formation, Deformation, And Incision Of Colorado River Terraces Upstream Of Moab, Utah, Andrew Jochems

Andrew Jochems

Fluvial terraces contain information about incision, deformation, and climate change. In this study, a chronostratigraphic record of Colorado River terraces is constructed from optically stimulated luminescence (OSL) dating of Pleistocene alluvium and real-time kinematic (RTK) GPS surveys of terrace form. This record is analyzed to relate terrace formation to late Pleistocene climate fluctuations, and terrain analyses and longitudinal profile patterns reveal recent salt-related activity in the northern Paradox Basin as well as patterns in Colorado Plateau incision.

A well-preserved, correlative suite of mainstem (M) fluvial deposits exists along the Colorado River upstream of Moab, Utah. Absolute dates indicate sedimentation >70 …

Updated Glacial Chronology Of The South Fork Hoh River Valley, Olympic Peninsula, Washington Through Detailed Stratigraphy And Osl Dating, Cianna E. Wyshnytzky, Tammy M. Rittenour, Glenn D. Thackray

Cianna E Wyshnytzky

Four glacial advances are preserved and exposed in the stratigraphy of the South Fork Hoh River valley. The oldest of these advances extended beyond the South Fork valley into the Hoh River valley. The three younger advances are preserved in the stratigraphy cut bank exposures in the valley and geomorphically by moraines and outwash plains. One of these advances represents a re-advance to the same terminal position of the previous advance and has not previously been recognized in this valley or other glaciated valleys in the western Olympic Mountains. This finding advocates for a detailed sedimentologic and stratigraphic approach to …

Appendix A: Borehole Data (Thesis Appendix, 2013), David J. Richey

David J Richey

Select borehole data compiled and organized from Utah Division Oil, Gas and Mining (www.oilgas.ogm.utah.gov). The data found here include API well numbers, names of all wells used, well datum as defined by the elevation above sea level measured at the Kelly Bushing on the drilling floor, and the depth to various formation tops encountered during drilling measured in drilling depth.
