Fabric Code: tpr291a

Samoan hybrid vitric

Brown glass, with some altered reddish glass. Basaltic rock fragments are mainly holocrystalline, with some vitrophytic and picritic.

Fabric Class:

Igneous Olivine: Dominated by igneous lithic inclusions with olivines.

Oceanic Basalt: Mainly contain olivines, clinopyroxenes and plagioclase, and have lathwork and mafic vitric lithic fragments.
