Prevalence of radiation from [Fe.sup.3+] (700 nm band) in the XRL spectrum of the endocontact quartz is related to faster cooling and influx of oxygen from the enclosing frame; faint [Fe.sup.3+] emission in the aplitic quartz (third phase) with intense radiation in the 620 nm band is most likely due to the final phase formation under conditions of slow cooling and lack of oxygen.
