Olivine does not naturally occur with the mineral quartz. Quartz can only form from magmas that are relative rich in silica, while the olivine minerals only form from magmas that are relatively less in silica, so quartz and olivine are incompatible minerals. THEY ARE NOT EXISTING AS TOGETHER COOLED CRYSTAL RATHER WHAT WE SEE THE FORSTERITE SILLICA SYSTEM IS THE MELT PHASE OF MAGMA ...THATS WHY ENSTATITE FORMED DURING THE PROCESS TO SEPARATE THEM...MEANS THEY REACT TO FORM SEPARATE PHASE.
