---|---|---|---|
37-332A | 37-332A-8-2,75-7 | Basalt with rare phenocrysts of plagioclase, and olivine and intergranular/intersertal groundmass of plag, cpx and magnetite. Some replacement by smectite, minor calcite +/- smectite in vesicles. | |
37-332A | 37-332A-12-1,81-83 | Basalt with rare plagioclase phenocrysts. Groundmass glassy, with plag, cpx +/- olivine, partially replaced by smectite. Vesicles partly filled with smectite and carbonate. | |
37-332A | 37-332A-17-1,50-52 | Aphyric basalt. Intergranular/intersertal groundmass of plag, cpx and magnetite. Glass partly replaced by smectite. Sparse vesicles filled with glass and Fe oxide. | |
37-332A | 37-332A-29-1,65-66 | Coarsely plagioclase-physic basalt. Mediumgrained, sub-ophitic groundmass of plag, cpx, magnetite and olivine. Glass and olivine sometimes altered to smectite; sparse vesicles lined with smectite. | |
37-332B | 37-332B-10-3,39-41 | Coarsely plagioclase-physic basalt. Coarsegrained groundmass of cpx, plag, olivine and magnetite. Some deuteric alteration of plagioclase to sericite. Some vesicles, partly filled with smectite and carbonate. | |
37-332B | 37-332B-16-2,63-65 | Basalt with rare phenocrysts, mostly olivine, some plagioclase. Fine-grained groundmass of plag, cpx, olivine and chrome-spinel microphenocrysts. Very vesicular. From distinctive pillowed sequence. | |
37-332B | 37-332B-25-1,106-113 | Glomerophyric basalt, with euhedral/subhedral phenocrysts of olivine and adhering clusters of plagioclase. Chrome-spinel as inclusions in divine phenocrysts and in groundmass. | Groundmass mostly aphanitic, some glass altered to smectite. Vesicles filled with smectite and carbonate. |
37-332B | 37-332B-35-3,91-95 | Coarsely phyric basalt, mostly olivine phenocrysts but some plagioclase and rare clinopyroxene. Common fresh chrome-spinel microphenocrysts. Coarsegrained groundmass with plagioclase laths. Much calcite, magnesite, siderite and smectite alteration. | |
37-332B | 37-332B-37-3,50-52 | Basalt with rare olivine phenocrysts. Otherwise similar to last sample, but less altered. | |
37-333 | 37-333A-11-1,91-92 | Moderately phyric basalt with plagioclase, clinopyroxene and less common olivine. Fine-grained intersertal groundmass. Some fresh glass, but mostly replaced by smectite. | |
37-335 | 37-335-14-4,130-143 | Moderately phyric basalt with plagioclase, olivine and rare clinopyroxene phenocrysts. Glassy to variolitic groundmass of plag, cpx and magnetite. Abundant interstitial smectite. Vesicles with smectite and carbonate. |
