Rs. Rawat et P. Kumari, HOMOGENIZATION EXPERIMENTS - AN AID IN MELT TEMPERATURE DETERMINATION- A STUDY FROM AMRITPUR GRANITE SERIES, KUMAUN LESSER HIMALAYA, INDIA, Neues Jahrbuch fur Mineralogie Monatshefte, (9), 1998, pp. 417-425
Significance of homogenization (quenching) experiments on the alkali f
eldspars and perthites is demonstrated. Homogenization experiments inc
lude high temperature studies at normal pressure. These studies have s
ignificance in determining the melt temperatures. Pure mineral separat
es of alkali feldspars from Amritpur Granite Series (AGS) were obtaine
d using conventional techniques. These separated alkali feldspars were
homogenized at 1050 degrees C for 48 hours, then quenched and powdere
d. XRD studies were carried out on these samples. A temperature of 700
+ 50 degrees C is concluded for the granitic melt of the AGS.
