Figure F35. Interpretative summary lithology and some key chemical and physical properties of the volcanic and sedimentary rocks sampled at Site 1137. The depth scale on the left shows the curated positions of the 10 basement units. The depth scale on the right shows the positions inferred from core-log integration (see "Physical Volcanology," "Downhole Measurements"). Vesicularity, degree of alteration, and loss on ignition indicate macroscopic characteristics and level of preservation of the volcanic rocks. Mg# = (molar MgO/[MgO + 0.80 × total FeO]), and Cr contents demonstrate downhole variations in chemical composition.
