SAMPLE INFO : 46AC135
Sample ID:46AC135
Station ID:46AC135
Latitude:51.9689
Longitude:-177.132
Datum:NAD83
Date Sampled:1946-01-01
Sample Type 1:Lava
Sample Type 2:Flow
Field Lithology:Basalt
Text Description:
Light-gray (N7) olivine basalt, compact, holocrystalline, porphyritic, with intergranular texture. The larger plagioclase crystals, ranging in width from 0.1 to 3 mm have a median composition, judging from the refractive index, of about An[63?]. Salite phenocrysts ranging in size from 0.1 to 5mm, have nZ 1.723, suggesting a composition of Ca50Mg27Fe23. The olivine crystals which range in size from 0.5 for 0.07 mm, have Nz 1.72, suggesting F076Fa24. Magnetite of ilmenite, in irregular grains, from 0.5 to 0.1 mm, is the principal accessory. The groundmass consists of plagioclase laths, with median composition from An37 to An15, with interstitial augite and magnetite or ilmenite grains, and partial outer rims of orthoclase on the plagioclase laths
