Sample info : 84Au-100
Sample ID:84Au-100
Station ID:84Au-100
Latitude:59.370457903791
Longitude:-153.4365593699
Datum:NAD83
Date Sampled:1984-01-01
Sample Type 1:Lava
Sample Type 2:Flow
Text Description:
Xenolith and host in lava flow (longest flow). Plagioclase, hypersthene, augite, olivine, and Fe-Ti oxide phenocrysts in a vesicular groundmass of plagioclase microlites, Fe-Ti oxides, pyroxenes, and brown interstitial glass. Olivine is subhedral to skeletal in form and is surrounded by a faint dusty zone of alteration. Xenolith: Plagioclase, hypersthene, augite, and Fe-Ti oxide phenocrysts in a holohyaline groundmass of interstitial brown glass. Both host and xenolith are very vesicular. The boundary between xenolith and host is transitional with pieces of the xenolith being incorporated into the host.
