This is part of the Mylor Slate Formation which form a consistent appearance
along the southcoast of Cornwall. They are old rocks, having formed
in the Devonian period ( Between 359 million and 419 million years old).
They are a part of the south Cornish coastline as much as the sand and the sea.
This is granite, rich in white plagioclase feldspar, quartz and little shiny specks of mica.
Granite can be found in large parts of Cornwall and helps form features like Bodmin Moor, Carn Brea and Carn Marth, and much of Penwith. You could say it forms the backbone of the county.
Granite was the first rock I ever saw as the raw art of the natural world.
More from the Mylor Slate beds. Here you can see patterns on the rock surface like the ancient flow of water.
In Geology, there is a concept that goes "the present is the key to the past". By observing what is happening in the present day, we can determine how rocks came to be how they are now.
When I look at nature, I sometimes marvel that what we see now could one day be a brief note in an ongoing history that expands over millions of years. What will that geological record show?
We are so determined to make our mark in the world, but over the geological timescale the only thing that may show in the future will be what we have inflicted upon this incredible planet.
