Is sphalerite a mineral or a rock.
The “Mississippi valley type” (MVT) deposits are epigenetic, stratabound, rhythmically banded ore with replacement of primary sedimentary features predominantly carbonate (limestone, marl, dolomite and rarely sandstone) host rocks. The mineralization is hosted in open space filling, collapse breccias, faults and hydrothermal cavities.
