Method and apparatus for determining the relative content of a first rock species and of a second rock species in a rock sample extracted from a wellbore. The method comprises adding a reactant to the rock sample, measuring a first information (P) relative to a first amount of compound produced at a first instant (T1) and a second information (P) relative to a second amount of compound produced at a second instant (T2). The method also comprises calculating the relative content of the first species in the rock sample from the first information (PT1) and calculating the relative content of the second species in the rock sample from the second information P). The method comprises determining a corrected amount (Cv) of compound generated by the reaction of the second species with the reactant at the first instant (T1), and calculating the relative content of the first species in the rock sample and the relative content of the second species in the rock sample based on the corrected amount (Cv).
