Variability In The Mass Flux Of The Ross Sea Ice Streams, Antarctica, Over The Last Millennium, Ginny Catania, Christina L. Hulbe, Howard Conway, Ted A. Scambos, C. F. Raymond

Geology Faculty Publications and Presentations

We synthesize previously published remote-sensing observations, radar data and model output to obtain a ~1000 year ice flow history for the Siple Coast ice-stream system in West Antarctica to investigate the timing and magnitude of changes in mass flux. The synthesized history shows significant short-term variability in ice-stream shear margin and grounding line position due to internal variability of the coupled system. The chronology highlights the interplay between adjacent ice streams, which implies that the behavior of any individual ice stream should not be examined in isolation. Furthermore, individual events cannot be fully interpreted without an understanding of the broad-scale, …

Magmatic Origins Of Plutonic Rocks Of The Cooke City Area, Montana, Skyler Mavor Jan 2012

Magmatic Origins Of Plutonic Rocks Of The Cooke City Area, Montana, Skyler Mavor

WWU Honors College Senior Projects

Archean bedrock outcrops exposed in the Cooke City area of southern Montana are part of the crystalline basement of the Wyoming Craton. These rocks are plutonic intermediate to felsic, and modal petrographic analyses characterize them as tonalite, trondhjemite, and granodiorite (TTG) as well as granite. Field relations indicate that magmatic bodies are small, and several generations of magma appear coeval. The presence of epidote, interpreted as a primary magmatic phase, indicates a mid- to lower crustal emplacement depth. Chemically, these rocks are similar to other Archean TTG, they are metaluminous with high AI2O3 (>15%), low Ti02 (1.5 GPa) melting …
