K-Ar and Rb-Sr apparent ages are approximately 100 times greater than the age of volcanism on the island. In addition, 87Sr/86Sr values for mica-bearing soils are as high as 0.7273 and contrast greatly with the nonradiogenic strontium in Hawaiian lavas (0.703 to 0.707). These measurements establish that the potassium- and strontium-bearing phases of the Hawaiian soils are not of local origin and confirm the importance of eolian transport of mica and other clays to the North Pacific.
