Title
(EN) SPECTROSCOPIC ANALYSIS OF ROCKS
(FR) ANALYSE SPECTROSCOPIQUE DE ROCHES
Abstract
(EN) The present disclosure concerns methods of identifying and quantifying constituent phases in rock samples based on spectroscopic measurements, methods of determining values of pyrolysis parameters for rock samples based on spectroscopic measurements, and methods of determining amounts of organic phases in rock samples based on spectroscopic measurements, as well as associated computer programs, computer-readable media, data carrier signals and data sets, and methods of compiling associated data sets for use in such methods.
(FR) La présente invention concerne des procédés d'identification et de quantification de phases constituantes dans des échantillons de roche sur la base de mesures spectroscopiques, des procédés de détermination de valeurs de paramètres de pyrolyse pour des échantillons de roche sur la base de mesures spectroscopiques, et des procédés de détermination de quantités de phases organiques dans des échantillons de roche sur la base de mesures spectroscopiques, ainsi que des programmes informatiques associés, des supports lisibles par ordinateur, des signaux porteurs de données et des jeux de données, et des procédés de compilation de jeux de données associés destinés à être utilisés dans de tels procédés.
