Gossan
is always a great word to know.
So is callithumpian. Does it mean:
| a screen or mat covered with a dark material for shielding a camera lens from excess light or glare. |
| a children's mummer's parade, as on the Fourth of July, with prizes for the best costumes. |

gossan
rust-coloured oxide and hydroxide minerals of iron and manganese that cap an ore deposit. Gossans form by the oxidation of the sulfide minerals in an ore deposit and they thus may be used as clues to the existence of subsurface ore deposits, especially if distinctive boxworks are present.
