Description

Low-temperature thermochronological method measuring helium accumulation in apatite grains to determine cooling ages and thermal histories. Involves helium extraction, parent isotope measurement, and alpha ejection correction.

Typical Equipment

  • ASI Alphachron He extraction line
  • Balzers PrismaPlus QMG 220 quadrupole mass spectrometer
  • Thermo Element 2 magnetic sector ICP-MS

Output Measurements

  • cooling ages
  • effective uranium concentration
  • thermal history
