Figure F70. Depth profiles of (A) Cl, (B) Na, (C) Na/Cl, and (D) K. Arrows = seawater concentration. Dashed line = sill depth at Site 1039. Error bars are smaller than or comparable to symbol size (see "Inorganic Geochemistry" in the "Explanatory Notes" chapter). Subunit 4A = gabbro sill, Subunit 4B = lower igneous section.
