Abstract :

In this paper, factors affecting chemical variance of elements has been investigated in microdiorite-quartz diorites from 120 km SE-Birjand in order to evaluation of history of magmatic evolutions.Results of major element modeling based on mass balance calculations and trace element modeling based on Rayleigh crystal fractionation models (FC), Assimilation and Fractional Crystallization (AFC), mixing combined with fractional crystallization (MFC) and mixing equations suggest that data trends is more consistent with magma mixing model. However, it seems that other processes also maight have played important role in genesis of these rocks.
