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. . .
