Mississippi Valley TypeZn (Cd)
- Type
- Cadmium-rich Mississippi Valley-type (MVT)
Zn-Cd deposit in Cambrian dolomites of the Qingxudong Formation, rich in nodular and framboidal sphalerite, a possible sign of biological mineralisation; its sphalerite is among the lightest in cadmium in the region. Indicative coordinates.
