SAMPLE INFO : 91CNI26
Sample ID:91CNI26
Station ID:91CNI26
Latitude:59.99421
Longitude:-153.16787
Datum:NAD83
Date Sampled:1991-01-01
Sample Type 1:Lava
 Text Description:
Porphyritic two-pyroxene andesite. Phenocrysts of plagioclase, clinopyroxene, orthopyroxene, and opaque oxides in a groundmass of microlites with subordinate interstitial clear glass. One of several diverse lithologies collected from single location consisting of avalanche debris sitting on top of Umbrella Glacier at ~2200 foot elevation. Location implies these all came from Iliamna, central peak. "i" denotes fist-sized rounded blobs of macroscopically different magma enclosed in homogeneous host.
