Claim 10:
11. A method for determining elemental composition of a rock formation, comprising:
positioning a discharge tool within a wellbore;
generating, using the discharge tool, an electrical discharge that interacts with the rock formation proximate to the discharge tool, wherein the interaction of the electrical discharge with the rock formation vaporizes a portion of the rock formation to generate a discharge plasma, and wherein generating the electrical discharge comprises passing least a portion of optical emission generated by the discharge plasma through an optically transparent window of the discharge tool that is positioned in view of the discharge plasma; and
determining, using an optical emission spectroscopy (OES) sub-system, an elemental composition of the portion of the rock formation based on the optical emission generated by the discharge plasma, wherein at least a portion of the OES sub-system is positioned within the wellbore.
