Mississippi Valley-type deposits

Keyword Definition

A strata-bound deposit of lead and/or zinc minerals in carbonate rocks, together with associated fluorite and barite. These deposits characteristically have relatively simple mineralogy, occur as veins and replacement bodies, are at moderate to shallow depths, show little post-ore deformation, are marginal to sedimentary basins, and are without an obvious source of the mineralization. Abbrev: MVT.
