| Description: | Total wt? 50 kg. The rocks recovered include a variety of metamorphosed oceanic rock types - principally plutonic volcanic rocks that have undergone grenschist- to amphibolite-grade metamorphism. Rock types include metagabbros metadolerite metabasalt and breccias primarily composed of fragments of the metamorphosed volcanics. A majority of the samples are large (> 5 kg) blocks of amphibolitized (uralitized) gabbro with coarse crystals of amphibole (after Cpx) and plagioclase (albitized?). Some of these samples show megascopic features of tectonism (ie crushing, cataclasis, sliken sides). Lesser amount of metabasalt and metadolerite are also epidotized and chloritized. All ingenous rx show veining and replacement by calcite and qtz. Sedimentary rocks include: coarse sandstones, conglomerates, breccias and foram-rich calcareous siltstone. Coarser rocks contain abundant clasts of metabasalt and metadolerite. Moderate sorting of subrounded clasts in s.s., silicate cement. 10% forams in calc-siltstone. Two bags each for HIG and Sol.
