SAMPLE INFO : 84Au-110
Sample ID:84Au-110
Station ID:84Au-110
Latitude:59.344624
Longitude:-153.439056
Datum:NAD83
Date Sampled:1984-01-01
Sample Type 1:Lava
Sample Type 2:Dome
Text Description:
Sample of Kamishak dome. Plagioclase, hornblende, hypersthene, augite, olivine, and minor Fe-Ti oxide phenocrysts in a fine grained holocrystalline groundmass of plagioclase microlites, Fe-Ti oxides, and pyroxenes. Hornblende is euhedral to subhedral, opacite-rimmed, and occasionally being replaced by hypersthene. This sample contains several xenoliths with similar mineralogy but very little groundmass. Hornblende in these xenoliths is very elongate and average grain size is smaller than in the host.
