Identification Of Heavy Rock


Recommended Posts


  All that glitters isn't gold. However if it glitters someone will by it.

This business of trying to I.D. a mineral from a photo, even a good photo, is some what of a futile exercise. Even an exemplary photo illustration in high quality geology texts can only give a crude notion of what the mineral is like in a natural setting. But I find this thread interesting non the less. I would guess Iron-- if I where to guess.

Yeah, like the blue cast in the photo. Visual id is very difficult which is why it is best to go with physical properties:

  1. Color
  2. Streak
  3. Hardness
  4. Cleavage or Fracture
  5. Crystalline Structure
  6. Diaphaneity or Amount of Transparency
  7. Tenacity
  8. Magnetism
  9. Luster
  10. Odor
  11. Taste
  12. Specific Gravity

I have toyed with the idea of putting a hyperlinked mineral test flow chart on the website for the minerals prospectors commonly run into.

Brett,

 Here is a sample pan out of a drill hole from some drilling I am doing up on a bench.

Notice how different the stringer of gold in the left side of the pan looks from your "gold".
