Type B. Sparse well sorted and rounded quartz-feldspar-lithics non-placer temper.
Type C. Abundant moderately sorted and subangular quartzofeldspathic non-placer temper sand.
Type D. Abundant moderately sorted and subangular quartzofeldspathic non-placer temper sand.
Type E. Abundant natural temper.
Type F. Abundant natural temper with sparse lithic fragments apparently added manually.
Abundant well sorted and partially placered temper, manually added and typically pyroxene-rich (Type G). Clinopyroxene dominant, but minor orthopyroxene
