Figure F2. Photograph of Section 187-1163A-7R-2 (Piece 2, 26-32 cm), showing a calcareous-clay cemented hyaloclastite breccia from Unit 2. Notice the concentric palagonite rim around the edge of the glass fragment and the basaltic clast with ~4-mm-wide chilled margin. This basalt clast contains small plagioclase microlites like those seen in the aphyric basalt of Unit 2.
