The Cornish Batholith – Thank Goodness!

Thank God for the Variscan Orogeny and our Granite intrusions!
It sounds soooo naughty, but luckily here in Cornwall around 280-290 million years ago a volcanic intrusion produced the backbone of Cornwall and provided us with mostly a good hard coastal face, currently taking a pasting.
If we were on sandstone…Cornwall could be a new age lost Atlantis!
Talking of Atlantis…..We wonder if the sea will dredge up even more clues to the past and reveal the hidden tree stumps at St. Michael’s Mount that hold the stories of Lyoness. They were last seen in the 50s, at lowest astronomical tide. There are probably only a few people living thinking the same thing as the story fades with time. They came down due to a significant wave…
“The Rev. William Borlase, who “cleared the British Antiquities from the obscurity they were immersed in” (Pool, 1986), had made a great discovery by drawing together strands of myth and legend to eventually, in Borlase’s eyes, becoming a factual sudden event. This was conveyed in a letter to the Dean of Exeter, Dr. Charles Lyttleton. His letter describes three-foot wide oaks found lying horizontally, with roots buried deeper than they could dig, lying in an easterly direction. On further inspection the afternoon walk revealed hazel and willow, from 300 yards below the high water mark (Borlase, 1756).
At this stage Borlase was already committed to informing Lyttleton that the tree stumps confirmed an ancient tradition that St. Michaels mount, was formerly situated in a wood. This backed up his theory, also written to Lyttleton, that a subsidence had occurred in that place.”
