SAMPLE INFO : 47AC80
Sample ID:47AC80
Station ID:47AC80
Latitude:51.8938
Longitude:179.636
Datum:NAD83
Date Sampled:1947-01-01
Sample Type 1:Lava
Field Lithology:Basalt
Text Description:
Specimen 47AC80 (137,150' E., 271,850' N.) is from a compact block on the rim of the crater of the westernmost part of the small parasitic cone of Sugarloaf. It also is an olivine basalt, with plagioclase averaging An64, olivine (Fa30) as much as 0.3 mm in diameter, augite less than 0.5 mm and green in hand specimen, and magnetite. The groundmass has an intergranular texture, with prisms of clinopyroxene and microlites of plagioclase (0.02 mm in diameter).
