The Provenance of Eocene Tuff Beds in the Fossil Butte Member of the Green River Formation of Wyoming: Relation to the Absaroka and Challis Volcanic Fields
… Based on age and proximity, the Absaroka and Challis volcanic fields are the likely sources of tephra deposits in Fossil Basin and the Greater Green River Basin. Calc-alkaline tephras in these lacustrine basins have similar magmatic characteristics to the tuff of Ellis Creek (48.4 ± 1.6 Ma) …

Assessment of Biomarkers of Intrauterine Inflammation Induced Preterm Labor
… possible biomarkers of intrauterine infection (Challis et al., 2002). Biomarkers are objective indicators of a certain medical state that can be measured using various laboratory procedures. The identification of biomarkers for intrauterine infection can help predict clinical outcome as well as …

PETROLOGY, GEOCHEMISTRY, AND AGE OF EXTENSION IN THE LOST TRAIL PASS DIKE SWARM, SOUTHWEST MONTANA
… swarms assessed by Simonsen (1997), and the Challis intrusive suites studied by Gaschnig et al. (2011), specifically the lithologically variable quartz monzodiorite suite. The EFDS at LTP and LTP pluton are likely sourced from reactivated arc magmas related to Sevier and Laramide orogenesis …

GEOLOGY, GEOCHEMISTRY, AND TECTONIC IMPLICATIONS OF THE SALMON CREEK VOLCANIC SEQUENCE, OWYHEE MOUNTAINS, IDAHO
… The Cenozoic section consists of: (1) silicic Challis volcanics of Eocene age; (2) Oligocene age orogenic andesites and mildly-alkaline basalts of the Salmon Creek volcanics (SCV); and (3)a Miocene to Pliocene age bimodal sequence of tholeiitic basalt and rhyolite. Based on the lithologic and …

Timing and drivers of exhumation in the hinterland of the North American Cordillera from detrital zircon U-Pb and (U-Th)/He double-dating
… and Mogollon Highlands, and the Idaho Batholith/Challis Volcanic Center. Samples north of the Transverse Ranges display a stronger arc signature, while samples south of them were sourced from the Mojave and Mogollon Highlands. 159 new (U-Th)/He ages obtained from a subset of the zircons analyzed …

The recurring appeals of the Mormon rhetorical vision
This study investigates the recurring appeals of the Mormon rhetorical vision, appeals that help account for the growth of the Mormon Church which is now eight million; Bormann's Fantasy Theme Analysis, a communication model that explains how small groups develop imaginative ideas and concepts …

ON A CONJUGATE CLASS OF SUBGROUPS DETERMINED BY A FORMATION
<p>This thesis is an investigation of the interrelationships between a formation f, a finite solvable group G, and G(,f) the residual of f in G. This study is developed by introducing the f-subgroups. It is proven that the f-subgroups of G form a characteristic conjugacy class of CAR-subgroups of …

Detection and potential impacts of nanomaterials released from building materials in the natural weathering environment
The use of (nano)-particles has increased over the past couple of decades, which includes incorporation into building materials such as lumber and cement. Since building materials are in the outdoor environment, incorporated (nano)-particles may be released into the environment and have unforeseen …

Tectonic implications of mantle source changes recorded by Eocene-Oligocene basalts from the Dillon volcanic field southwest Montana (USA)
… to coevally with the 51-40 Ma central Idaho Challis and the 54-44 Ma Absaroka volcanism. Multiple tectonic models have been proposed to explain the ~33-16 Ma middle and upper Dillon volcanism (e.g., Farallon slab rollback, slab tearing/foundering, lithospheric drip), which erupted during the …
