|---|---|---|---|---|---|---|---|
| Veins per meter: | 19.99 | 7.95 | 3.05 | 4.04 | 10.87 | 1.82 | 0.12 |
| Abundance of vein-filling minerals (vol%): | 3.47 | 1.65 | 0.39 | 0.13 | 0.91 | 0.46 | 0.002 |
| Abundance of secondary minerals in breccia (vol%): | 0.28 | 0.004 | 0.28 | ||||
| Abundance of vesicle-filling secondary minerals (vol%): | 2.32 | 0.71 | 0.001 | 0.05 | 1.512 | 0.044 | 0.0004 |
| Abundance of secondary minerals occupying veins and breccia (vol%): | 3.75 | 1.65 | 0.39 | 0.13 | 1.19 | 0.46 | 0.002 |
| Total secondary mineral abundance (veins, breccia, and vesicles) (vol%): | 6.07 | 2.35 | 0.39 | 0.18 | 2.7 | 0.5 | 0.003 |
Veins per meter was normalized to 100% recovery. Volume percent was calculated based on the surface area that each alteration feature occupied on the cut surface of recovered core. Raw data sourced from visual observations (web.iodp.tamu.edu/UWQ/).
