Question

Quizplus · Accepted Answer

MVT (Mississippi-Valley Type) deposits are secondary enrichments primarily of lead and zinc. These deposits are found in sedimentary rocks and are formed by the movement of groundwater which dissolves lead and zinc from the original source and then redeposits them in areas of the rock where the water flow slows down or changes direction. Rarely, they can also contain small amounts of other metals such as copper and silver.
