Analyses were made of uranium and thorium in zircon, sphene, apatite, epidote, and monazite separated as accessory minerals from samples of granitic rock from widely scattered localities to indicate the abundance, and the natural distribution of these two components among the five mineral phases. The approximate distribution of the two elements in the accessory mineral phases, taken in pairs, is tabulated. (auth)
