Scawt Hill Marble

Notes:

Stylolitic pale yellow to white marble. Originally a pure chalk limestone deposited during the latter part of the Cretaceous geological period 66-77 Ma, this became metamorphosed approximately 50 million years ago when the chalk was altered through contact with a vertical intrusion, or dike, of the igneous rock Dolerite. This also led to the development of a suite of hydrated calcium-silicate metamorphic minerals including Larnite, Portlandite and Scawtite which were described from this locality for the first time.
