ESD’s Mack Kennedy participated in a reconnaissance investigation of noble gas radionuclides (39Ar, 81Kr, and 85Kr)
in gas emissions from several geothermal features at Yellowstone
National Park, to explore tracer applications of these nuclides in an
active hydrothermal system. The investigation included discovery of:
- Abundances of 39Ar, 81Kr, and 85Kr in gas emissions at Yellowstone
- 81Kr isotopic abundances yielding a residence time of < 100 kyr
- 39Ar isotopic abundances indicating contributions of nucleogenic Ar from rock.
