Refining The Onset Timing And Slip History Along The Northern Part Of The Teton Fault, Rachel Montague Hoar
Refining The Onset Timing And Slip History Along The Northern Part Of The Teton Fault, Rachel Montague Hoar
Theses and Dissertations--Earth and Environmental Sciences
A new apatite (U-Th)/He (AHe) dataset from subvertical transects collected in the Teton and Gallatin Ranges in the Teton-Yellowstone region provides insight for the slip history and length of the Teton fault. Along the northernmost segment of the Teton fault, inverse thermal history modeling of AHe data from Eagles Rest Peak yield a ~9 Ma age for onset of fault slip. This age supports previous interpretations that Mount Moran may be the true center of the Teton fault. This refined interpretation coupled with lengthdisplacement fault scaling analysis and previous estimates of total fault displacement (~6 km) indicates that the Teton …
