What is stratiform deposit?

What is stratiform deposit?

In mineral deposit: 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.

What are disseminated deposits?

Deposit in which usually fine-grained ore minerals are scattered throughout the rock. Large, disseminated deposits form important sources of ore, e.g. porphyry copper deposits.

What are sulfide deposits?

Volcanogenic massive sulfide ore deposits, also known as VMS ore deposits, are a type of metal sulfide ore deposit, mainly copper-zinc which are associated with and created by volcanic-associated hydrothermal events in submarine environments.

How are stratiform clouds formed?

Stratiform cloud may form during a warm front passage due to the steady, continuous rain falling from nimbostratus cloud, adding substantial amounts of humidity to the air. The cloud may form ahead of the front, in the cold air mass, or behind the warm front in the warm air mass.

What is the difference between stratiform and stratabound?

The terms stratum, bed and layer require precise definition. The terms stratiform orebody and stratabound orebody are defined and it is suggested that stratiform orebodies are a particular form of stratabound orebodies. (b) Those orebodies in which the ore has the form of a layer, i.e., of a stratum.

How are disseminated deposits formed?

The disseminated mineral deposit is a geological body, and mostly consists of metallic ore mineral in low concentrations. They are formed by a number of geologic processes and, in most cases, contain very large amounts of ore.

What does stratabound mean?

stratabound means contained within beds or layers of rock; Sample 1. Save. Copy.

What are epithermal deposits?

Epithermal deposits are a type of lode deposit. They contain economic concentrations from a precious metal such as gold and silver, and in some cases base metals such as copper, lead, iron ore and zinc.

Where do VMS deposits occur?

VMS deposits consist of massive or semi-massive accumulations of sulphide minerals which form in lens-like or tabular bodies parallel to stratigraphy or bedding. VMS deposits form on, or below, the ocean floor and are typically associated with volcanic and/or sedimentary rocks.

Is sulphide and sulfide same?

sulfide, also spelled sulphide, any of three classes of chemical compounds containing the element sulfur.

What is a stratiform deposit?

Stratiform deposits are formed as large sheet-like bodies, usually formed in layered mafic to ultramafic igneous complexes. This type of deposit is used to obtain 98% of the worldwide chromite reserves. Stratiform deposits are typically seen to be of Precambrian in age and are found in cratons.

What is a stratiform cloud?

Stratiform. Any of the stratus family of clouds ( fog, stratus clouds, altostratus clouds, cirrostratus clouds, nimbostratus clouds) and the precipitation coming from them.

What is stratiform precipitation?

Jump to navigation Jump to search. Stratiform may refer to: Any of the stratus family of clouds (fog, stratus clouds, altostratus clouds, cirrostratus clouds, nimbostratus clouds) and the precipitation coming from them. Any occurrence of layered strata (see stratigraphic unit).

What is the thickness of a chromite layer in a stratiform deposit?

Chromite can be seen in stratiform deposits as multiple layers which consist of chromitite. Thicknesses for these layers range between 1 cm to 1 m.
