Mineral Ore Deposits: Meaning, Origin and Types Geology

An ore deposit may be either of igneous or of sedimentary origin. Some deposits are related to metamorphic processes and are as such classified as deposits of metamorphic origin. Within these three broad modes of origin, a mineral deposit of economic value might have originated due to set of simple or complex processes. Types of Ore Deposits: 1.

ORE DEPOSIT TYPES AND THEIR PRIMARY EXPRESSIONS K.G ...

PRIMARY EXPRESSIONS OF ORE DEPOSITS A well known aspect of ore deposit expression is the association of particular ore types with particular host rock assemblages, i.e., the ore-host rock association (e.g., Stanton, 1972). This association broadly reflects the geological environment and processes that have formed the ore.

CLASSIFICATION OF DEPOSITS

Magmatic deposits are syngenetic in that the ore minerals crystallize from the same liquid that produces the silicate minerals which form the bulk of the intrusive - they crystallize more or less simultaneously as the melt cools.

Introduction to Mineral Deposit Models

An "ore deposit" is a mineral deposit that has been tested and is known to be of sufficient size, grade, and accessibility to be producible to yield a profit. (In these days of controlled economies and integrated industries, the "profit" decision may be based on considerations that extend far beyond the mine itself, in some instances relating ...

Magmatic ore deposits (Chapter 2) - Ore Deposit Geology

Magmatic ore deposits, also known as orthomagmatic ore deposits, are deposits within igneous rocks or along their contacts in which ore minerals crystallised from a melt or were transported in a melt. Ore deposits that form in and around igneous rock units as a result of mineral precipitation from aqueous solutions or hydrothermal fluids are hydrothermal ore deposits.

Classification of Mineral Deposits Geology for Investors

Feb 04, 2021  Most mineral deposits are formed by more than one process, so attaching a single label to them is difficult. Hence, there is a tendency to talk about Stillwater Complex type or Carlin-type gold deposits, which rather defeats the purpose of finding a general from the specific. There are two main approaches to mineral deposit classification.

Ore Deposit - an overview ScienceDirect Topics

Magmatic ore deposits may be defined as rocks of igneous origin (see IGNEOUS PROCESSES), which can profitably be mined for their constituent chemical elements.For example, the worth of annual global production from magmatic ore deposits exceeded $10 billion in 2001, and dominates or contributes significantly to world supplies of elements representing

Ore - Wikipedia

An ore deposit is one occurrence of a particular ore type. Most ore deposits are named according to their location (for example, the Witwatersrand, South Africa), or after a discoverer (e.g. the Kambalda nickel shoots are named after drillers), or after some whimsy, a historical figure, a prominent person, something from mythology (phoenix ...
