Greenstone - Porthleven Cliffs (S17)

The rocks in the Porthleven Cliffs are mainly fine grained sedimentary rocks ( turbidites).
When the turbidite sediments were still wet and unconsolidated , they were intruded by basaltic sills.
In the Pic , Mylor Slates (Turbidites) are on the left with Metadolerite (Greenstone) on the right , a sill some 10metre thick , the Contact Zone is bleached.

Access to the beach , on a low tide, from Porthleven or Loe Bar.
