2019-10-1 · The (Na + K)/Al ratio of carbonate phases ranges between 24 (globule with the lowest Si, Al and Fe abundances) and 1.7 (globule with the highest Si, Al and Fe values). The Na/K ratio is 3.1–8.6 and the Ca/(Na + K) ratio, considered to indicate how close the globule is to natrocarbonatite, is 0.8–1.8, with an average value of 1.3.
