ORE DEPOSIT TYPES Ore deposits can be classified on the basis of: - • Composition of the deposit (contained elements). • Form of the deposit (size, shape, orientation and ore mineral distribution). • Associated host rocks or geological structures (ore associations). • Interpreted genesis of the deposit (processes, controls).3.1.1.

Jun 21, 2019 · This presents a zinc/lead ore with a potential for silver and gold. Conclusion. While Jamaica has a long history of mining, it's exploration potential is far from exhausted. There is potential for new deposits and deposit types hosting metallic minerals based on mineralization related to mafic/ultramafic and granitoids rocks and faulting.For more facts about ore, go over the corresponding lesson called What Distinguishes Ore from Other Mineral Deposits? This lesson covers the following topics: Overview of ore deposits

Mineral Deposits - definition of Mineral Deposits by The .

A "mineral deposit" is a mineral occurrence of sufficient size and grade that it might, under the most favorable of circumstances, be considered to have economic potential. 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.Ore is a deposit of one or more valuable minerals. A deposit is a buildup of minerals in one place. Deposits develop naturally. Most ore deposits are found underground. The most valuable ore deposits contain useful metals. These include copper, gold, iron, and aluminum. Such metals have many important uses. We all depend on them.

Mining for ore isn't what it used to be. A hundred years ago when a mining operation happened upon a copper vein or a gold deposit, the outfit would often just rip out the local flora, excavate the land, and dump the resulting waste and rubble in the nearest pristine stream or flowering meadow.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.

arrangement (structure), which can be expressed in a unique X-ray diffraction pattern. In order to exploit the different elements, it is best to produce the elements from places where different processes have lead to their enrichment. In nature, such a place is called a mineral deposit or an ore deposit. An ore deposit .A mineral deposit can be classified as an ore deposit when? A) valuable metals in the deposit can be mined at a profit. B) valuable metals are present in the deposit. C) it contains valuable gemstone quality minerals. D) it contains valuable fossil fuels.

Chemical element - Ore deposits | Britannica

Ore bodies of types 1) and 3) are conformable with regional ore-field and ore-deposit structures. Fissure fillings are the predominant shape of ore bodies. The relation of ore bodies to rock permeability, regional tectonics, and brecciation are analyzed as a guide for future prospecting. --M. Russell.Hydrothermal mineral deposits are accumulations of valuable minerals which formed from hot waters circulating in Earth's 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.

VEIN DEPOSITS - Earth Science

Metals occur in all kinds of rocks but usually in concentrations that are too low to be mined. Metallic ore deposits, however, are relatively rare concentrations of metal‐bearing minerals (usually sulfides) that contain enough metal to be profitably mined.Again, the profit line .A List to some Major Types of Ore Deposits and a link Book Download. Komatiite-associated nickel deposits Layered mafic-ultramafic intrusion deposits Skarn deposits Fractionated granitoid-associated deposits Porphyry-associated deposits Iron oxide copper gold deposits Syn-deformational hydrothermal and replacement deposits Orogenic gold deposits Carbonate-hosted stratabound lead-zinc deposits .

dilation of pre-existing structures, leading to deposit-scale focussing of ore-fl uid and gold deposition. Anticlinal or antiformal fold hinges, particularly those of ' locked-up ' folds with .The major role played by pre-existing structures in the formation of vein-style mineral deposits is demonstrated with several examples. The control of a pre-existing decollement level on the formation of a crustal extension-related (collapse) gold deposit is first illustrated in .

Ilmenite - Wikipedia

What is Chromite? Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4).It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite-bearing rocks are altered by heat or weathering.Most of the silver produced today is a byproduct of mining copper, lead, and zinc. The silver occurs within the ores of these metals in one of two ways: 1) substituting for one of the metal ions within the ore mineral's atomic structure; or, 2) occurring as an inclusion of native silver or a silver mineral within the ore mineral.
