| Description: | Total recovery 600 lbs (~250 kg) of oceanic basalt from within the median rift valley. Approximately 70% of samples have glassy rims and margins (generally < 1 cm). At least 50% have features that indicate they were extruded onto the sea-floor as pillows or lava tubes. Some non-glassy fragments may have been parts of pillows but subsequently lost their glassy rinds. Only ~ 5% of samples are slightly coarse grained and holocrystalline - these maybe interior of flows or dikes. About 85% of the samples have rough, crumbly coating that appears oxidized, palagonitized and Mn- coated. 15% are extensively Mn- coated (< 1 cm thick). All samples are extremely fresh - with alteration constrained to pillow margins or along major fractures. The angular nature of the samples suggest they were recovered in situ. Also: 20 lbs foram-rich dull yellow orange mud. 15% forams, some sponge spiculas and diatoms in clay matrix. 3 plastic bags: Exon, HIG, Solomons. 21 samples were described in detail and glass splits were taken for analysis. Larger splits of these were put in a separate bag for B. Taylor (HIG). Extra samples were distributed to: 3 Bags Solomons; 3 Bags HIG. |
