|---|---|---|---|---|---|
| 183-1136A-15R-2,30-36 | Olivine-plagioclase glomerophyric basalt, vesicular (15%), incompletely crystallized, with intersertal texture. | Phenocrysts (10%-15%) are tabular crystals of plagioclase (labradorite) with size 0.3-1.2 mm and single grains of olivine. | Groundmass is plagioclase lathe, clinopyroxene, opaque minerals, and interstitial glass (10%-15%). | Moderate (~25-30%); vesicles infilled with smec and chl. PhX of olivine completely replaced by smec and chl. Oxidation of basalt low (~5%). | Smectite and hydromica in trace amounts |
| 183-1136A-16R-1,113-118 | Sparsely plagioclase phyric basalt, vesicular (~8%). Groundmass demonstrates intergranular texture. | Phenocrysts represented by tabular crystals of plagioclase (0.4- to 3-mm labradorite compose up to 5% of rock) and single grains of olivine. | Groundmass is plagioclase lathe, clinopyroxene, single grains of olivine, opaque minerals and dust, and interstitial glass (5%-7%). | ~15-20%; vesicles infilled with smec and chl. PhX of olivine/interstitial glass completely replaced by smec and chl. Oxidation of basalt low (~3-5%). | Smectite |
| 183-1136A-17R-2,84-90 | Sparsely plagioclase phyric basalt, weakly vesicular (~5%; 0.08-0.15 mm), incompletely crystallized, with intergranular texture. | Phenocrysts of tabular crystals of plagioclase (up to 1 mm) labradorite (~5% of rock). | Groundmass is plagioclase lathe (45%-50%), clinopyroxene (30%-35%), opaque minerals (5%), and interstitial glass (10%). | ~15%; interstitial glass completely replaced by smec and chl. Rock is nonoxidized. | Smectite |
| 183-1136A-18R-2,62-67 | Plagioclase phyric basalt, vesicular (~10%), incompletely crystallized, with intersertal texture. | Phenocrysts of tabular crystals of plagioclase (0.3-2.5 mm) labradorite (5%-10% of rock). | Groundmass is plagioclase lathe (45%-50%), microlathe of clinopyroxene (30%-35%), opaque minerals (2%-3%), and interstitial glass (10%-15%). | ~15%-20%; vesicles infilled with smec and chl; interstitial glass completely and partially replaced with smec and chl. Rock is nonoxidized. | Smectite |
| 183-1136A-19R-1,27-31 | Plagioclase phyric basalt, vesicular (~10%), incompletely crystallized, with interstitial texture. Sample is same as Sample 183-1136A-18R-2,62-67. | ~10%-15%. Rock is nonoxidized. | Smectite |
