Figure F15. Dissolved lithium (Li+) concentration profile at Site 1247 (solid circles) shown with those from Site 1245 (dashed line) for comparison. Both data sets show an increase in lithium concentration with depth. At the depth of Horizon A there is an enrichment in interstitial lithium at both Sites 1245 and 1247, perhaps indicating fluid migration from deep-seated fluids.
