   "abstract": "The Dixie Valley fault bounds the east side of the Stillwater Range in west\u2010central Nevada and last ruptured in 1954. Offset basalts indicate that slip began more recently than ~14 Ma, and prior work has interpreted the southern segment as an active low\u2010angle normal fault. Oligocene igneous rocks in the southern Stillwater Range were steeply tilted during large\u2010magnitude extension prior to ~14 Ma. To refine the timing of early extension and the onset of slip on the Dixie Valley fault, we collected two transects of samples for apatite fission track, apatite and zircon (U\u2010Th)/He (AHe and ZHe), and apatite\u00a04He/3He thermochronometry. Apatite fission track ages from the Oligocene IXL pluton indicate rapid cooling ~18\u201314 Ma, and AHe and ZHe ages from the Cretaceous La Plata Canyon pluton indicate rapid cooling ~16\u201319 Ma. We interpret these data to record cooling during rapid extension. AHe ages from the IXL pluton are ~6\u20138 Ma and record cooling during slip on the Dixie Valley fault. We modeled these ages and\u00a04He/3He spectra from one sample as the result of cooling during exhumation of a tilted fault block at a constant extension rate. The model predicts slip on the Dixie Valley fault beginning ~8 Ma. Although it does not constrain the initial fault dip, the model illustrates how a low\u2010angle fault requires a higher extension rate to reproduce cooling ages. Consequently, we prefer a high\u2010angle southern Dixie Valley fault for strain compatibility with the high\u2010angle northern segment.",
