Origin Of Ore Deposits

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.

Origin Of Ore Deposits | Processes of Ore Formation ...

The epigenetic ore deposits formed by hydrothermal solutions are called “hydrothermal ore deposits”. The ore deposits which are commonly formed by the hydrothermal process are gold, silver, copper, lead, zinc and mercury. Classification of Hydrothermal Deposits 1.

Ore Deposits: Origin, Exploration, and Exploitation ...

Ore Deposits: Origin, Exploration, and Exploitation is a valuable resource for economic geologists, mineralogists, petrologists, geochemists, mining engineers, research professionals, and advanced students in relevant areas of academic study.

Ore Deposit - an overview | ScienceDirect Topics

Ore deposits can be exclusively formed under sedimentation processes such as iron ore formation (banded iron formations [BIF]/banded hematite quartzite [BHQ]), diamond in conglomerate, zinc-lead deposits in dolomite, and limestones.

Ore | mining | Britannica

Copper, lead, and zinc are frequently found in massive sulfide deposits. Many such deposits are believed to have been formed by precipitation from volcanic exhalations on the seafloor or by metasomatic replacement (a process of simultaneous solution and deposition). No ore deposit consists entirely of a single ore mineral.

Hydrothermal mineral deposit - Wikipedia

Hydrothermal mineral deposits are accumulations of valuable minerals which formed from hot waters circulating in Earths crust through fractures. They eventually create rich-metallic fluids concentrated in a selected volume of rock, which become supersaturated and then precipitate ore minerals. In some occurrences, minerals can be extracted at a profit by mining.

Ore - Wikipedia

Ore deposits. 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 …

Mineral deposit - Hydrothermal solution | Britannica

Mineral deposit - Mineral deposit - Hydrothermal solution: Hydrothermal mineral deposits are those in which hot water serves as a concentrating, transporting, and depositing agent. They are the most numerous of all classes of deposit. Hydrothermal deposits are never formed from pure water, because pure water is a poor solvent of most ore minerals.

Processes of Ore Formation

Processes of Ore Formation. Current theories of the genesis of ore deposit can be divided into internal (endogene) and external (exogene) or surface processes. It must be understood that more than one mechanism may be responsible for the formation of an ore body.

GEOG 303 Midterm 2 Flashcards | Quizlet

Does the Pebble ore deposit have a hydrothermal origin? Yes, as a porphyry deposit the Pebble deposit does have a hydrothermal origin. Copper and gold were at one time carried from the core by hot water from hydrothermal systems and deposited near the Earths crust.

Iron Ore in Africa - Mining Africa

The History of Mining Iron Ore Iron ore was excavated and steel was forged as early as 1800BC. This was discovered when ironware was excavated from archaeological sites in Anatolia. Steel weapons like the falcata in the Iberian Peninsula were also produced in early years.

Mining History in the United States – Legends of America

Lake Superior copper was first mined by the whites in 1771, and in small quantities. In the early colonial days the settlers used stone for fuel, and charcoal for the forge and smelting-works. Coal, however, was found in Rhode Island in 1768, and mined for use. The great bituminous seam near Pittsburgh, Pennsylvania was struck in 1784.
