Estimating the term…
The disclosure relates to determining a mineralogical composition of a geological sample, comprising estimating mineralogical and elemental compositions of the sample using measurements. The method also predicts an elemental composition from the mineralogical composition, and corrects the measured mineralogical composition, by: adjusting an amount of a mineral within a minerals family with keeping total amount of minerals of the family constant, correcting total amount of a minerals family within a system comprising several families with keeping relative amounts of each mineral within the family constant, adding an amount of additional minerals while keeping the relative amount of each predetermined minerals constant, It also comprises determining a match indicator of the predicted and measured elemental compositions, comparing the indicator values for the initial predicted and corrected predicted elemental compositions, and outputting the measured or the corrected mineralogical composition depending on the comparison result.
Method for determining a mineralogical composition of a sample of a geological formation, comprising:
The method according to the preceding claim, comprising performing iteratively the correction sequence until convergence.
An installation for determining a mineralogical composition of a sample of a geological formation, comprising:
