| Comment: | Mixture in the basket. Pyroclastic ejecta from Prometheus & Hades. (Prometheus position info given). ~70% fresh dense to moderately vesicular spatter some clasts with smooth surfaces with the remaining 30% altered or dense crystalline lava clasts. These crystalline clasts are more olivine-rich than the glassy fragments. The finer fraction is mostly moderately dense angular glass fragments and broken crystals of opx cpx and ol. Some ol is spinel-bearing and others are spinel-free. Rare fluidal glass fragments occur in the finer grain size fraction. The sample had a strong smell of S as it dried out in an oven at 60¡C and contained rare S spherules. One yellow echinoid spine is also present. The glass is gray colored. |
