Mississippi Valley-Type (MVT) Lead-Zinc. ... Prior to the opening of the Pine Point mine in 1965, deposits of this type contributed only negligibly to Canadian lead-zinc production. Since that time, however, about 30% of annual production has been derived from Mississippi Valley-type deposits.  3, record 1, English, - Mississippi%20Valley%2Dtype%20deposit

Sangster (1976) has divided carbonate-hosted base metal deposits into two major types: (1) Mississippi Valley, and (2) Alpine. Other workers do not make this distinction and refer to all low temperature carbonate-hosted deposits as being of Mississippi Valley-type. Sangster contends that the first type, which are strata-bound, were emplaced after lithification of the host rocks and were largely controlled by pre-ore structures, whilst he considers the Alpine-type to be stratiform and syndsedimentary. ... However, because this distinction is made by some workers on a global basis, the author has avoided using the term Mississippi Valley-type for all carbonate-hosted base metal deposits.  5, record 1, English, - Mississippi%20Valley%2Dtype%20deposit
