| Locality type: | Pegmatite Field |
| Classification |

|
| Species: | Columbite-(Fe) |
| Formula: | Fe2+Nb2O6 |
| Comments: | Ferrocolumbite forms tabular crystals, generally no more than 1/4 inch thick and 1 inch by 1 inch in plan. The principal faces of most of the crystals are flat, but some very thin and broad crystals are markedly curved. Many of these platy individuals are 1/16 inch or less in thickness and as much as 4 inches in maximum dimension. They occur in radiating groups. A few crystals are more equant, and appear as subhedral to euhedral "chunks" 1/2 inch to 6 inches in diameter, with an average of about an inch. |
| Colour: | Dull black on crystals faces; bright submetallic luster on freshly broken surfaces. |
| Abundance at site: | Common |
