| Comments: | The results of LA-ICP-MS showed that Kamakanga emeralds from Zambia had stable and high contents of alkali metals (Li, Na, K, Rb, Cs) in the range of 15,120 to 20,407 ppmw (avg. 17,592 ppmw). The alkali metal concentrations, from highest to lowest, were Na, Cs, Li, K, and Rb. The Na contents ranged from 12,343 to 23,517 ppmw (avg. 15,981 ppmw); the Cs contents ranged from 626 to 2724 ppmw (avg. 1331 ppmw); the Li contents ranged from 301 to 843 ppmw (avg. 485 ppmw); the K contents ranged from 119 to 573 ppmw (avg. 369 ppmw); and the Rb contents ranged from 21 to 248 ppmw (avg. 68 ppmw). Chromophore Cr, V, and Fe contents, respectively, ranged from 76 to 2934 ppmw (avg. 1435 ppmw), 78 to 183 ppmw (avg. 128 ppmw), and 5136 to 11,320 ppmw (avg. 8556 ppmw). The concentration of Cr was much higher than that of V and the Cr/V ratio was highly variable, ranging from 0.70 to 34.35. In addition, Zambian Kamakanga emeralds had high contents of Cs (avg. 1331 ppmw), Fe (avg. 8556 ppmw), and Li (avg. 485 ppmw). |
