SAMPLE INFO : 91CNI11i
Sample ID:91CNI11i
Station ID:91CNI11i
Latitude:60.01098
Longitude:-152.99019
Datum:NAD83
Date Sampled:1991-01-01
Sample Type 1:Lava
Sample Type 2:Enclave/Inclusion
Text Description:
Basaltic andesite magmatic inclusion. Abundant microphenocrysts of plagioclase (0.5 x 0.7 mm) and pyroxene (0.5 mm). Groundmass consists of smaller plagioclase laths, pyroxene, opaque oxides, and a few tens of percent of clear glass. Irregular voids largely bounded by crystals are abundant. One of several diverse lithologies collected from single location consisting of avalanche debris sitting on top of Red Glacier at ~2400 foot elevation. This location is at a fork in the glacier, and these samples could have come from either the main cone or North Twin. This location covered by subsequent rock/snow/ice avalanches (seen in landsat image on GE). "i" denotes fist-sized rounded blobs of macroscopically different magma enclosed in homogeneous host.
