Lawrence, D.J., Feldman, W.C., Barraclough, B.L., Binder, A.B., Elphic, R.C., Maurice, S., Miller, M.C. and Prettyman, T.H. (1999). High resolution measurements of absolute thorium abundances on the lunar surface. Geophysical Research Letters 26: doi: 10.1029/1999GL008361. issn: 0094-8276.

The Lunar Prospector (LP) Gamma-Ray Spectrometer (GRS) has been used to map the global abundance of thorium on the lunar surface. A global map of absolute thorium abundances on a 2¿ by 2¿ equal-area pixel scale is presented using new detector modeling results and low altitude LP data. Because thorium is relatively abundant in KREEP-rich material, these data provide fundamental information regarding the locations and importance of terranes that are rich in KREEP bearing materials. ¿ 1999 American Geophysical Union
