The woman who quit engineering to become a rock star

Scotland’s rich geology includes Lewisian Gneiss.

At about three billion years old they are Scotland’s oldest rocks and found in parts of the Hebrides and north-west Highlands, Luisa’s favourite place for geology.

There are also volcanic rocks on the coast of the East Neuk of Fife and geological features such as the Moine Thrust, which was formed when two ancient continents collided about 430 million years ago.

Luisa said: “The geology of Scotland is fascinating and there have been so many different discoveries here.

“You can go across 500 miles and come across all these different rock types.”

On the impact of her work, she adds: “I think I have made a difference.

“I was in Braehead shopping centre and a guy who recognised me from the videos came up to me and said: ‘Oh man, I never thought about rocks before’.”
