Fig. 5: Nano-SIMS analysis of reactions products formed in 18O-enriched solutions.
From: Kinetically driven successive sodic and potassic alteration of feldspar

Products within 1 day (A–D) and 5 days (E–H). A, B, E, F BSE images showing the reaction products; (C, G) oxygen isotopes maps; (D, H) 18O/16O line profiles of locations shown in C, G. Note the brighter field in left side of C is due to charging issues, which result in higher counts of ions detected (Supplementary Fig. 5).
