Hi Fang-Zhen - Neat stuff. You likely know that Be isotopes and B/Be ratios are thought to indicate rapid inputs of subducted materials into erupted arc magmas. Could K isotopes lead to an entirely new story about whether sediments or AOC is the source of arc enrichments, since K isotopes seem to separate these so well? Perhaps that key is to measure K isotopes for arc rocks with B-Be-related enrichments? -Keith
