We collected samples from the Black Nunataks, Melvoldt Nunataks, Mason Peaks, Zakharoff Ridge, Mount Harding, and the northern Gale Escarpment. Geochemical analysis indicated that in some samples the amount of Rb was higher than 300 ppm. This suggests that rocks from the Grove Mountains are rich in Rb. Based on field observations and previous research, we speculate that mica and potash feldspar from moyite, granite gneiss, and felsic pegmatite are the primary carrier minerals of Rb.
