Stratiform Deposits Article about Stratiform Deposits by

In the capitalist countries, stratiform deposits account for about 40–60 percent of the lead-ore reserves and 35–40 percent of the zinc-ore reserves. The term “stratiform deposits” was introduced at a conference on the origin of such deposits held in New York in 1969.

Mineral deposit Mississippi Valley type Britannica

Stratiform deposits. A final class of hydrothermal deposit is called stratiform because the ore minerals are always confined within specific strata and are distributed in a manner that resembles particles in a sedimentary rock. Because stratiform deposits so closely resemble sedimentary rocks, controversy surrounds their origin.

Definition of strata-bound Mindat.org

Said of a mineral deposit confined to a single stratigraphic unit. The term can refer to a stratiform deposit, to variously oriented orebodies contained within the unit, or to a deposit containing veinlets and alteration zones that may or may not be strictly conformable with bedding.

Series: Handbook of Strata-Bound and Stratiform Ore Deposits

Regional Studies and Specific Deposits deals with regional studies of strata-bound and stratiform ore deposits. Topics covered include the geological association between coal and metallic ores; the genesis of iron ores in banded iron-formation (BIF) by supergene and supergene-metamorphic processes; mineral zoning in sediment-hosted copper deposits; and the formation of gossans.

6. SEDEX, VMS, MVT Minerals Earth Sciences

Stratiform vs. Stratabound Classification SEDEX deposits are distinctive in that it can be shown that the ore minerals were deposited on the bed of an ocean or marine environment in a second-order basin environment, related to discharge of metal-bearing brines into the seawater.

Sediment-Hosted Stratabound Copper Deposit Model USGS

Jun 17, 2015· SSC deposits are the second most important sources of copper in the world behind porphyry copper deposits. Around 20 percent of the copper in the world is produced from this class of deposits. They are also the most important sources of cobalt in the world, and they are fourth among classes of ore deposits in production of silver.
