Fabric Code: tpr290a

Samoan crushed microlitic lithic

Feldspathic-lithic sand temper. Microlitic rocks. Crushed-rock tempers. May be from hawaiite rather than basaltic rocks.

Fabric Class:

Felsitic-Microlitic Feldspathic: Dominated by felsitic and/or microlitic inclusions with feldspars.

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