Description
Shell Content
Shelly Whitbed - Predominantly grey shells with some large white shell fragments. The shells are mainly large thin clams up to 100mm long laid parallel to the bedding.
Shell Distribution
The Shells are randomly distributed across the stone, but due to the large clam shells, some banding is evident particularly in larger slabs.
Texture
The large clam shells are associated with voids. The texture in between the voids is often tight and dense.
Colour
Typical Portland Colour - creamy/white, although the large concentrations of grey shells can darken the overall colour.
