Carbonate-hosted lead-zinc deposits of the mississippi valley type are thought to have formed through the migration of warm (50 degrees -150 degrees C) subsurface fluids in sedimentary basins. The fundamental role of fluid flow is poorly understood; depending on the stage of evolution of a basin, either a compaction-drive or gravity-drive fluid-flow …

sedimentation). Stratiform and stratabound are also essential terms in mineral deposits formed by sedimentary processes. Thus, a stratiform deposit means a mineral deposit related to a con-crete stratigraphic bedding, while a stratabound deposit is limited to a determined part of the stratigraphic column. Many terms are used in relation to the ...

The variation in As content of pyrite from three gold deposits (Agnico-Eagle, Quebec; Fairview and Pilgrim's Rest, South Africa) has been studied by color-staining polished surfaces with a solution of KMnO 4 in 1:1 H 2 SO 4 followed by electron microprobe analysis. Pyrite grains from strata-bound and stratiform gold deposits are commonly …
The terms stratiform orebody and stratabound orebody are defined and it is suggested that stratiform orebodies are a particular form of stratabound orebodies. The …
Ore Deposit Types. The unifying characteristics of the volcanogenic massive sulfide deposit type are (1) association with volcanics, and (2) mineralization by hydrothermal …
The major stratiform Zn-Pb-Ag deposits exhibit many similar geological and geochemical features that include: 1) location close to regionally extensive normal and strike-slip synsedimentary faults ...
The stratiform-type ore bodies constitute a marginal to low Mn grade and are also characterized by lower Mn content (26.19–39.24%) along with the Mn/Fe ratio of 7.16–12.23, while the stratabound-type Mn ore bodies are rich in Mn (35.92–49.64%) along with the higher Mn/Fe ratio of 14.15–23.97.

These stratabound to stratiform copper deposits are described in several provinces over the world, e.g., the central Africa copper belt in Zambia and Zaire, central Europe copper belt, Dongchuang ...
A stratiform (see below), usually lens-shaped mineral deposit consisting of at least 60% sulphide minerals.
The average grade of an ore deposit is calculated, often employing very sophisticated statistical procedures, as an average of the grades of a very large number of samples collected from throughout the deposit. ... Stratiform A mineral deposit which occurs as a specific stratigraphic (or sedimentary) bed. Stratabound A mineral deposit which ...
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 …

Ore deposit study and the development of guides for their exploration is the objective of metallogeny. Besides the series of synthetic books on the geology of ore deposits referred in the present paper, Hedenquist et al. offer a recent synthesis of the metallogenic concepts for most deposit types. In the future, the consumption of mineral ...

Stratiform to stratabound replacement of a mixed siliciclastic-carbonate host rock is a defining characteristic of many sediment-hosted base metal deposits. Mineralized rocks in clastic-dominated (CD-type) Zn-Pb ore deposits, which represent our highest value base metal resources, are generally thin (10 1 m), laterally extensive (10 3 m), and ...

A stratabound deposit is defined as a type of mineral deposit where ore minerals are exclusively confined within a single specific stratigraphic unit, which may include various orientations of mineralization such as layers, veins, stringers, and alteration zones.
Stratiform and stratabound are also essential terms in mineral deposits formed by sedimentary processes. Thus, a stratiform deposit means a mineral deposit related to a concrete stratigraphic …
