摘要：

The approximate degree of partial melting of a primary magma can be calculated using the variation in concentration ratios of two incompatible trace elements. The method is based on the difference in enrichment ratios caused by different bulk distribution coefficients. The advantage of the method is that it can be used for different melting models and is completely independent of assumptions about the source concentrations. The limitation of the method is that reliable results require bulk distribution coefficients with an accuracy better than 30%.
