Pyrite Concretions, Tea Cove, Newfoundland

This is not a new locality but is a very old one, rediscovered!! If you look in Dana's System of Mineralogy,Seventh Edition, published in 1944, you'll see a reference to the "pyrite concretions on the west coast of Newfoundland". I imagine that they were noted in earlier editions, as well. The concretions are as notable now as they were then. These unusual concretions are eroded out of shales by wave action and then sit in the water on top of the shale rock. Thet take on a charming bronzey cast and are solid pyrite. Very dense. They occur in a variety of sizes, some extremely large. Some are smooth potato like masses and others are smooth masses with sharp crystals attached. Unique!!

  • A more typical sedimentary, shale-formed spheroidal concretion showing the bands of shale imprinted on the outside of the form. A cluster of pyrite crystals clustered on top. You can't tell from the photos but it actually flying saucer shaped! Nice looking piece!

  • A large, flattened, golden potato! Dense! This large concretion has been released from the shale and rumbled around the bottom of the cove for a hundred years or so. Super example! Needs the right amount of postage!

  • This is another interesting piece! It appears to have been part of a larger sheet of pyrite but a part of it that swelled out into a spheroidal concretion with large, sharp cubed of pyrite congregated at one end. Interestingly, the pyrite crystals have amounts of the shale adhering to the middle portion of each cube face sort of resembling inverted hoppers. Very interesting piece!
