Abstract
High-energy laser ionization of geologic materials is a
potential replacement for conventional stable isotope
extraction techniques because the former requires less sample
material, requires less sample preparation and, most
importantly, may allow direct in situ analysis. The laser
extraction process explored in this study uses a pulse,
focused Nd:YAG laser to excite the surface of carbonate and
hydrous minerals producing a plasma. The plasma subsequently
cools and condenses to form stable gaseous species such as CO
and CO2 from carbonates or H2 and H20 from hydrous minerals.
These species may be cryogenically separated and analyzed to
obtain their isotopic compositions. . .
