| Field Name: | Lava, Enclave/Inclusion |
| Description: | Basaltic andesite magmatic inclusion. Sparse phenocrysts of plagioclase. Microphenocrysts of plagioclase and pyroxene. Groundmass is dominantly crystalline and consists of 40 x 250 micro plagioclase laths, 150 micron diameter pyroxene, and subordinate clear glass. Irregular voids largely bounded by crystals are abundant. Opaque microcrystalline masses up to 1.4 mm long may be relict amphibole. 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. |
