Sedimentary exhalative deposits (SedEx deposits) are ore deposits which are interpreted to have been formed by release of ore-bearing hydrothermal fluids into a water reservoir (usually the ocean), resulting in the precipitation of stratiform ore.. SedEx deposits are the most important source of lead, zinc and barite, and a major contributor of silver, copper, gold, bismuth and tungsten. However, we have visited most of the mining districts cited in the text and have also corresponded extensively with geologists to extend our knowledge beyond the published literature. Nonetheless writing a text-book on Ore Deposits is a demanding task and it is inevitable that sins of both omission and commission have been committed.
Ore is natural rock or sediment that contains one or more valuable minerals, typically metals, that can be mined, treated and sold at a is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals.. The grade of ore refers to the concentration of the desired material it contains. The capacity of hydrothermal fluids to transport metals in concentrations sufficient to form ore deposits is due in large part to the polar nature of the water molecule and the ability of metals to form strong aqueous complexes with a number of ligands commonly found in nature.
Kula Misra has met that challenge and produced a first-rate book that reviews the techniques employed in ore deposit research and summarize the geological and geochemical characteristics and origins of selected classes of metallic ore deposits. In a field that generates new data daily, Understanding Mineral Deposits is up-to-date useful. With. There are two distinct types of copper deposits: sulfide ore and oxide ore. Currently, the most common source of copper ore is the sulfide ore mineral chalcopyrite, which accounts for about

PROF. NIGGLI has followed his important monograph of on the function of the volatile constituents in petrology by an interesting essay on their importance in the classification of ore deposits. Ore deposits that are associated with mafic to ultramafic igneous rocks can generally be divided into those where the metals of interest are hosted in oxide minerals and those where the metals of interest are held as sulfides or are strongly associated with sulfides (e.g., PGE alloys, arsenides, bismuthinides).
The oxide ore bodies include stratiform, podiform, and breccia-related chromite. Understanding ore textures is fundamental to unraveling the genesis of an ore deposit, which in turn allows exploration and mining geologists to build their conceptual models of the deposits they encounter and leads to more successful exploration and exploitation.
The keeping of deposits is one of the chief functions of banks at the present time and is directly connected with the currency function.
Two classes of deposits, however, must be distinguished.

The following eight chapters describe critical elements in a number of important ore deposit types. These chapters include a description of the deposit type, major deposits, critical element mineralogy and geochemistry, processes controlling ore-grade enrichment, and exploration guides.
Ore deposits are crustal concentrations of useful elements that can be exploited at a profit. The basic requirements for any ore deposit to form are described. Classification of ore deposits based on (1) composition, (2) form of deposit, (3) associated host rocks and geological structures, and (4) interpreted genesis is described.
Some ore deposits are called Magmatic Deposits, meaning that the ore minerals grow in a magma. Many important ore deposits are formed by hydrothermal circulation, meaning that in association with the intrusion of hot magma, hot water starts to circulate.

The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, % Fe), hematite (Fe 2 O 3, % Fe), goethite (FeO(OH), % Fe), limonite (FeO(OH)n(H 2 O), 55% Fe) or siderite (FeCO.

Some giant ore deposits are formed from magma, but the precise controls on their formation are unclear. A Perspective article analyses the distribution of .Alternatively, the ore-forming process which generates very large deposits may be significantly different.
The concern here is not with the well-known size differences between deposits of different geological type that contain the same metal (i.e., the difference between porphyry copper deposits and volcanogenic massive sulfide deposits as.
