Rock property measurements based on spectroscopy data

A non-transitory computer-readable medium comprising computer-executable instructions that, when executed by at least one processor, cause the at least one processor to perform operations comprising:

• obtaining data characterizing concentrations of a set of one or more elements in a geological formation based at least in part on at least one measurement of the geological formation;
• providing the data characterizing concentrations of the set of one or more elements in the geological formation as an input to a nonlinear mapping function;
• and
• receiving, as an output, at least one parameter characterizing the geological formation, wherein the at least one parameter characterizing the geological formation represents a value of one or more rock properties of the geological formation.
