Such pegmatites are widely exposed in Sec. 22 T.39N. R.17E (Kohler, 1988, 1989). Columbite-tantalite is also found as crystals up to 2 cm long in a pegmatite in the NE SW SE Sec. 29 T.39N R.17E (Koehler, 1989, personal communication). Some of this material has been shown to be manganocolumbite and manganotantalite (Falster et al., 1995).

Tantalite's greatest difference from columbite is its much higher specific gravity, 8.0+ compared to columbite's 5.2. Other properties that vary slightly are color, transparency and streak. Both minerals can be found more or less together in granitic pegmatites rich in lithium and phosphorus minerals with columbite concentrated at the edges of
