Below this level, a high temperature zone occurs characterised by prehnite and pumpellyite.

These mineral assemblages also contain pumpellyite, prehmte or prehnite+actinolite in a few samples.

Later metamorphic events are manifested by the formation of uralite, secondary biotite and titanite, chlorite, sericite and prehnite.
