| Description: | Two bag: - 1 HIG; - 1 Solomon Is. Geol Survey. Total recovery ~50 kg of cobble to boulder size rocks. Approximately 1/2 was vesicular basaltic volcanic rock and holocrystalline dolerites. The remainder of the samples were various types of volcanoclastics including one large (~15-20 kg) boulder. Another 15-kgs was various clay-ash-clastic partially indurated clays (put in bag #1). The basaltic rocks are primarily olivine-Cpx-plag phyric basalts with 5-30% vesicles. The most abundant basalt type is Cpx-rich with lesser 01+/- plag. One possible trochyandesite and a tonalite (xenolith) were also recovered. All of the samples are reasonably fresh (< 10% replaced), but the amounts of secondary minerals in vesicles varies from 0 - 60%. None of the samples were glassy - most appear to be fragments of flows. Their rounded nature suggests they have had some history of erosion and redeposition. Some of the lavas were enclosed in volcanoclastic material. One basalt contains a xenolith of tonalite. Less than 10% of the rocks were ophyric, there may have been dikes. 35 samples have veeb cut + described for later analysis. The volcaniclastics very from strongly indunated lithic rudites, lithic tuffs, crystal tuffs to silty volcanic sandstones (which also act as matrices for the basalt cobbles. |
