Trace element abundance relationships in the multi- stage comagmatic fractional crystallization and their applications

  • Wang Yunliang 
  • Li Juchu 


In this study a mathematical expression of trace element abundance relationship for the multi-stage comagmatic fractional crystallization has been established, based on geochemical studies of the Emeishan basalt- trachyte series and adjacent mafic-ultramafic layered intrusions, as well as on the available data for basalt, andesite, dacite and rhyolite series in southern Andes, Chile, which have been well documented. It is demonstrated that the abundance constant (R) for a given trace element at different stages of fractional crystallization of a parental magma is highly variable, which can be used as a criterion to divide fractional crystallization stages.
