Refractory element mobility in volcanic soils
Refractory trace element concentrations in strongly weathered Hawaiian soils ranging in age from 20 to 4100 ka are highly elevated over parent rock values due to extensive mass loss of more soluble major elements during pedogenesis Nb and Ta exhibit virtually no mobility Soil Nb/Ta ratios are within the range of fresh bedrock even when soil
