Raymond J. Durrheim and Walter D. Mooney used seismic and geochemical constraints to compare Archean and Proterozoic lithosphere. Their work tests proposed relations between crustal age, thickness and lower-crustal structure.[ref]
Evolution of the Precambrian lithosphere: Seismological and geochemical constraints by Raymond J. Durrheim and Walter D. Mooney. Abstract: crustal evolution and preserved velocity-depth profiles
Combining rock composition with wave-speed measurements helps distinguish candidate structures that a single travel-time measurement would not identify uniquely.
