Thorium and uranium concentrations in the pelitic-schists and granitic gneisses in Joshimath-Badrinath area of Central Crystalline Axis, show gradual decrease with increase in metamorphism up to anatectic stage. The leucogranites of anatectic origin show unusual increase in uranium. The distribution suggests that with increase in metamorphism these elements were expelled. At a late stage there was uranium enrichment as indicated by scattered distribution in the leucogranite, ranging from 5 ppm to 32ppm.- Occurrence of Molybdenite in the Granites or Pirancheru near Hyderabad, Andhra Pradesh
