Sample Locations for Thermochronometric Analysis of Recent deformation across the Basin and Range (NERC Grant NE/N015479/1)
Locations of samples collected to constrain the recent activity on normal faults across Nevada. The geological samples will be used to measure the amount of exhumation that different normal faults of the Basin and Range experienced over the last 5 million years. The samples have been collected from granitic rocks that are expected to yield apatite crystals. (Uranium-Thorium)/Helium thermochronometry will be conducted on these samples to determine the cooling history of rocks from temperatures of approximately 70 degrees celsius. The samples are collected across Nevada at locations close to the fault to determine the most recent stages of exhumation. The ranges sampled are the Wassuk Range, White Range, Toiyabe Range, South Egan Range, Schell Range, Wheeler Range, House Range, Wasatch, Deep Greek, Ruby Range, Cortez Range, Humbolt Range, Dixie Valley, and Carson Range. Samples weigh approximately 2kg each. This sample coverage will constrain extension rates across the Basin and Range which is of interest to geologists, geodynamicists, and researchers interested in fault hazard.

Data Quality
The locations of sampling sites were selected based on preliminary modeling to determine which locations will reveal the most about recent deformation. Samples were collected by driving to the footwall of normal faults and hiking to locations that contained granitic rocks suitable for sampling. The samples were stored in plastic bags and securely sealed with duck tape. They were transported back to the UK in hold luggage. The samples are in the process of being crushed so that grains of apatite can be extracted from the granite.
