Types Of Ore Deposits

Stockwork texture, veins amd breccia are typical types of rocks. If the formation is caused due to hydrothermal alternation, then the ore is classified as an epigenetic formation. Examples: El Teniente, Chile. Volcanogenic Massive Sulphide (VMS)

Abstract In order to understand and appreciate various geochemical processes of ore deposits and be able to use appropriate geochemical methods to explore specific mineral/ore deposit(s), knowledge on ore deposit types is paramount. This chapter presents the origin and genesis of different types of ore deposits. Ore deposits of economic value constitute metals that occur

Bauxite, the well-known ore of aluminium, is a typical residual accumulation in most cases. Ores of iron like limonite, goethite and hematite and of manganese like psilomelane and pyrolusite are other examples of residual deposits. Similarly, deposit of

Ore Deposits. Most ore deposits contain metals in a reacted or combined form, such as magnetite (Fe3O4), hematite (Fe2O3), goethite (αFeO(OH)), limonite (generic formula for limonite is FeO(OH)·nH2O), and siderite (FeCO3), which are iron ores, and Cu5FeSO4, which is a copper ore.

HYDROTHERMAL ORE DEPOSITS TYPES OF ORE DEPOSIT 1. Ores formed by hydrothermal processes 2. Ores formed by igneous processes within the earth 3. Ores formed by sedimentary processes at the Earth’s surface A hydrothermal fluid = a hot, aqueous fluid containing dissolved metals in solution. A mineral vein is formed when minerals precipitate in a fracture.

The rock within which ore deposit occurs. Volcanic or pyroclastic rocks; Plutonic or subvolcanic rocks; Ultramafic rocks; Carbonate rocks; Sedimentary rocks; Evaporitic rocks; Wall rock or country rock. The rock which surrounds the ore deposit, in particular, the rock on either side of a vein. Volcanic or pyroclastic rocks; Plutonic or subvolcanic rocks

mineral deposit types and commodities. The most important metallic deposit type in Afghanistan is sediment-hosted copper represented by the Aynak and associated deposits (section 7.1). Deposits and occurrences of lead and zinc and barite also are present in the central part of the country (section 7.2). Industrial minerals that formed due to sedimentary processes

Often a deposit will contain a mixture of all three types of ore. Where are ore deposits found? Mineral deposits have been found both in rocks that lie beneath the oceans and in rocks that form the continents, although the only deposits that actually have been mined are in the continental rocks. (The mining of ocean deposits lies in the future.) See also what is human

06/12/2012· The readers are acquainted with paleohydrogeological analysis of these conditions for different types of ore deposits, namely (1) ore deposits formed in artesian basins, in which sedimentary rocks were predominant both at the time of magmatic activity and in the periods free of this activity; (2) ore deposits formed in artesian, ad artesian basins (and admassifs)

Ore deposits according to this grouping may be characterized as exogenetic if their origin is due to surficial processes such as weathering or shallow sedimentation with little or no relation to tectonics. Most petrology books concern themselves only with unweathered rocks. The few books in existence on ore petrology give too little consideration to weathering processes, to

Major deposits are characterized by ore minerals contained within organic-rich pyritic shales and sandstones deposited in a near-shore lagoonal environment, under reducing conditions. These mineralized sediments are always found above oxidized terrestrial clastic sediments. Two of the largest and most well known deposits of this type are the European Kupferschiefer and the

Ore deposits are an economic term and the beds are a geological term. All factors affecting the mining, processing and transportation of ore must also be considered. Such factors include a form of deposit, depth under the surface, geographical distance, access to transport, political stability of the region, and market factors such as the price of metals in world trade and

environments and the key geologic manifestations of the different deposit types form the footprints of ore systems that are targeted in exploration programs. Important progress has been made in our ability to integrate, process, and visualize increasingly complex datasets in 2D GIS and 3D platforms. For gold exploration, important geophysical advances include airborne

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 to the overall health of a national economy.)

Types of Ore Deposit Models Types of Ore Deposit Models. A descriptive model is a refined, site specific classification method for ore bodies. They identify the volume of ground needed to describe the extent of pertinent geological phenomena. There is further subdivision of the model into spatial sub-regions that allow for geological variability to be shown at manageable scale to

29/07/2013· Quite simply, if geologists can classify mineral deposits based on rock types, geologic settings and formation conditions, then they can start to make useful predictions of where other similar deposits might be. For example: porphyry copper deposits are associated with the circum-Pacific ring of fire; lateritic bauxite deposits in stable tectonic areas exposed to tropical

Porphyry deposits typically contain hundreds of millions of tonnes of ore, although they range in size from tens of millions to billions of tonnes; grades for the different metals vary,
