| Description: | 300 kg - 3/4 of dredge was full: top 3/4 was full of cobble size pumice with tan to light grey color containing mineral phenocrysts, fragments and pumaceous rock fragments. The bottom 1/4 of the bag was filled with vitrophyric basalts which commonly had a pitchstone-like surface with concordal fractures. These basalts have variable percentages of vesicles and in some cases grade into lighter-colored pumaceous basalt. Typical pumice cobble: tan to lt-grey with 80-90% clear to tan glass in sheaths and strings, These strands are welded together to form denser rock sections most show preferred linear flow orientation and flow bonding. They contain pumice shards as well as mineral grains and clost (plagioclase, magnetite, cpx). Basalts are glassy to finely crystalline with plag, cpx, magnetite +- ol. Some of the volcanics may be basaltic andesites or andesite. Phenocryst contents vary from ~5% to ~35%, vesicle content 5%-70%. 2 bags pumice to Sol. Is., 1 bag of described samples SI. 2 bags pumice to HIG, 1 bag of described samples HIG. |
