摘要
A method for determining mineralogical or geochemistry of at least one geological sample with vibrational spectroscopy combined with laser-induced breakdown spectral measurements performed on the geological sample in a time variant manner with spectral acquisitions made after each of a plurality of measurement shots, spectral pre-processing performed as necessary, and subsequent analysis is applied to the collected data to determine at least one mineralogical or geochemistry parameter of the sample. The method can provide a rapid method to estimate mineralogy or geochemical parameters of a sample, which does not require sample preparation, and which can be non-destructive with respect to portions of the sample. A system for performing the method also is provided.
