摘要: Abstract Rare earth element concentrations in zircons and apatites separated from dacites granites have been measured. Partition coefficients between phenocrysts of zircon apatite the groundmass materials may be explained by crystal structure minerals. The rare patterns appear to reflect liquid phase at earlier stages crystallization.
