    1. Hello mate, I've found a lot of the casts but this was the first that I noticed the crystals also the others were from the stoneless clay this one came from a thin gravel seem in the clay , ile try get some better pics of the crystals the best way to describe the long thin ones is needle like ?

  2. The needle like long thin ones are best described as prismatic crystals. The crystal point shown at bottom right of pic 8 is I think a little too "sharp" to be quartz, i.e the angle of the point looks wrong. I'd love to see a close up mate,

  5. Hi Heath,
    Excellent pics. Not quartz, I think they're aragonite crystals. Aragonite has the same chemical composition as calcite, but with a different crystal lattice. With your permission, I'll post a few of your pics on Mindat for verification.
    Cheers,
    Rog
