TBY E

Provenance: 
Local colluvial-alluvial soils
Clay: 
The matix is optically active, non-calcareous (or contain very small quantaties of caronate), iron-rich and silty. The silty component (3-10%) contains well sorted angular to rounded quartz grains (predominant), opaque minerals, plagioclase (rare) and olivine (very rare).
Temper: 
The temper (3-15%) contains rounded to sub-rounded quartz (predominant), rare opaque minerals, olivine, plagioclase and very rare rounded limestone, nari, chalk, weathered calcite grains and soil balls with quartz and foraminifera inclusions. The absence of chert is notable.
