Radiogenic Isotopes & Geochronology
Geochronology: Dating Capability
The UT Chron Lab houses three state-of-the-art, all metal, ultra-high vacuum noble gas extraction and purification lines for measuring 4He as well as a a Thermo Helix SFT magnetic sector mass-spectrometer with dedicated UHV extraction and purification line for 4He/3He and low 4He yield samples.
Also included are facilities for picking and grain measurement, as well as rapid, fully automated cathodoluminescence (CL) imaging in the E-Beam Lab for trace element zoning prior to ablation.

Radiogenic Isotope Facilities
TIMS Lab is a state-of-the-art facility capable of measuring Rb-Sr, Sm-Nd, Re-Os, U-Th-Pb and U-series isotopes in a variety of materials, with the goal of resolving fundamental questions in the fields of geology, hydrology, archaeology and environmental science.
The PIs for this facility are Jay Banner and John Lassiter
Fission Track Thermochronology
Fission Track Thermochronology Laboratory enables analysis of fission tracks in apatite and zircon to constrain the low-temperature time-temperature (t-T) history of sedimentary, igneous, and metamorphic rocks.

Dedicated clean rooms include:
- Banner Lab for preparation of rock, mineral, soil, plant and water samples for chemical and isotopic analysis under low-contamination conditions. Contact Staci Loewy for details.
- Lassiter Lab allows ultra-clean sample preparation and ion-exchange chromatography for isotopic analysis. Contact Staci Loewy for details.
- Two additional laboratories with HEPA-filtered work stations for sample preparation and ion-exchange chromatography.
