Stratiform deposit mineralogy Britannica

2021-5-8  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.

Stratiform Deposits Article about Stratiform Deposits

In stratiform deposits, there is a predominance of stratified bodies that are conformable with the enclosing rocks. The ores in these bodies have simple mineral compositions determined by the dissemination of copper, zinc, and lead sulfides and the accompanying minerals in one or more strata of the ore-bearing rocks.

Such deposits are referred to as stratiform. Stratabound ore deposits are any type of orebodies, concordant or discordant, which are restricted to a particular stratigraphic horizon. Concordant orebodies are found in different kinds of sedimentary rocks. Limestones:

Stratiform Deposit - an overview ScienceDirect Topics

Mississippi valley-type epigenetic deposits. Stratiform deposits of predominantly galena and sphalerite are most commonly hosted in shallow-marine carbonate-dominated sequences on the rims of large sedimentary basins where changes in salinity caused deposition. The continental regions of Southeast Asia, with their extensive Palaeozoic carbonate platforms, are suited to Mississippi Valley-type

The former may be subdivided into sedimentary, volcanic, hypabyssal, vein, replacement and metamorphic types.

Stratiform Deposits Article about Stratiform Deposits

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.

Stratiform Chromite Deposit Model - USGS

Stratiform chromite deposits are found throughout the world, but the chromitite seams of the Bushveld Complex, South Africa, are the largest and most intensely researched. The chromite ore is located primarily in massive chromitite seams and, less abundantly, in disseminated chromite-bearing layers, both of which occur in the ultramafic section ...

Sediment-Hosted Stratabound Copper Deposit Model

2015-6-17  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.
