Interesting Breccia found in Brough Bay.

Students from Aberdeen University had a visit Brough Bay in 2016 lead by 
Professor John Parnell.

One of their many finds was this piece of rock, (breccia) from the fault zone in Brough Bay, showing mineralization by lead (galena, lead sulphide, looks shiny grey) and zinc (sphalerite, zinc sulphide, looks reddish brown).

Thanks to John Parnell for sending us the picture.
