Petrographic And Physical Factors Controlling Thermal-Conductivity Of Granitic-Rocks In Illinois Deep Holes Uph 1, 2, And 3, Yoram Eckstein, Peter Dahl, Charles J. Vitaliano

Peter Dahl

Twenty-four granitic core samples from the Illinois deep drill holes yield thermal conductivity values in the range 29.3–37.6 mW/cm °C, wet bulk densities in the range 2.608–2.960 g/cm³, and water accessible porosity in the range 0.12–0.78%. Thermal conductivity values vary with modal quartz content of the rocks at all depths, and both parameters decrease linearly with depth between 673 and 1016 m in drill hole UPH 3. Below 1070 m there is no systematic variation in modal quartz content with depth and hence no systematic variation in thermal conductivity. Similarly, no systematic variations in modal quartz or physical …

Influence Of F(Oh)(-1) Substitution On The Relative Mechanical Strength Of Rock-Forming Micas, Peter Dahl, Michael J. Dorais

Peter Dahl

Microtextural and experimental studies have yielded conflicting data on the relative mechanical strengths of muscovite and biotite [Wilson and Bell, 1979; Kronenberg et al., 1990; Mares and Kronenberg, 1993]. We propose a crystal-chemical resolution to this conflict, namely, that (001) dislocation glide in biotite is rate-limited by its fluorine content. Significant F(OH)₋₁ substitution, and concomitant removal of hydroxyl H⁺ directed into the interlayer cavity, potentially increases mechanical strength of biotite in two ways: (1) it eliminates K⁺-H⁺repulsion, thereby strengthening the interlayer bonds, and (2) it allows K⁺ to “sink” …

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.
