This view shows more of the white laminations appearing as we excavate f415 (see v233). As in the last case, the layers soon disappeared, returning to the brown of f415. It seems certain at this point that we are indeed looking at multiple events: as the laminations built up, the brown of f415 also built up. Then, new layers of laminations and new layers of brown material rose on top of them. The only question left unanswered is, which feature came first, relatively speaking? That is, did the first brown layer precede the first lamination, or vice versa? v234a is a closeup of the layers themselves. [Input: N805JL.j] |
