Stainton Beck - Magnetic Basaltic Andesite & Fossil Beds

Heath Barnes is a geology & paleontology field researcher in his spare time. He has discovered and excavated portions of the Stainton gravel beds in Cleveland, UK. His fossil finds are very impressive, and are detailed in his blog "History of a Beck."

As well as Auroch skulls, worked tools and a human tibia, he also discovered that magnets stick to boulders of basaltic andesite from the nearby Cleveland dyke. Heath asked on Mindat (mineral database & forum) about the magnetic attraction. I became interested and visited him, below is my post on the mineral forum thread "Magnetic rocks again."

Heath Barnes noticed something I found highly surprising - that you could stick a neodymium magnet to a lump of basaltic andesite. More mineralogical magnetic surprises have been found by Josele from Spain, and he has posted images of magnets sticking to various crystals on the Spanish FMF mineral forum. A fascinating website concerning the use of rare earth magnets as an aid to gemstone identification can be found here.
