Normalizing rock and mineral composition data to chondrite standards is a widely accepted geochemical practice that facilitates consistent comparison of rare earth and trace element patterns across diverse geological and environmental samples.
The retrieved literature consistently confirms that normalizing rare earth element (REE) and trace element concentrations to chondritic abundances is a standard methodological practice in geochemistry. Papers [0], [2], [3], [7], and [11] all explicitly utilize chondrite normalization to standardize data, evaluate fractionation patterns, and enable meaningful comparisons across different rock types and environmental matrices. There are no papers in the provided set that challenge or refute this foundational analytical approach.
