✦ Synopsis

The kerogen of Torbanites of various origins (natural and laboratory-heated samples) was examined by quantitative Fourier transform infrared spectroscopy (FT-ir.). This study was carried out from difference spectra, obtained by low temperature ash (LTA) subtraction, or from deconvoluted regions of such spectra. The various indexes thus obtained allowed for determining the degree of natural and artificial evolution of Torbanites and the associated changes in chemical structure; comparing artificial versus natural evolution; and assessing the oil potential retained by matured Torbanite samples. The scopes and limitations of these
