Abstract: Precambrian coeval basic rocks metamorphosed
equivalent to low grade amphibolites fecies, have been granized along their fractured
zones. Biotite selvages/surmicaceous endaves are formed as a result of the advent
of potash rich solutions with the continuation of elevated temperature. Sufficient
supply of metasomatising material and fractured zones have facilitated the complete
transformation of the metabasic rocks into granodiorite leaving a biotite rich zones
in the Bramhajoni Hill,Gaya,Bihar.
