This patent describes a method for investigating, through logging, an earth formation transversed by a borehole. It comprises: determining, by logging the the borehole, the indications of at least two indexers; determining a value for at least two dominant attributes, including at least one mineral, of the formation by operating with an indexer-to-attribute transform on the at least two indexers, wherein the dominant attributes are identified by a multivariate statistical analysis on data obtained from a formation; and generating a tangible record of the values of the dominant attributes.
