Metallic Deposits CliffsNotes

High‐grade supergene gold and copper deposits can form also when a low‐grade deposit is weathered down ward, and the metal accumulates in place. A rusty, iron‐bearing cap called a gossan is often the only remnant of a weathered metallic ore deposit at the surface.

ore National Geographic Society

Ore is a deposit in Earth’s crust of one or more valuable minerals. The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron. Copper ore is mined for a variety of industrial uses. Copper, an excellent conductor of electricity, is used as electrical wire.

Metallic ore deposits The Geology of Chile

This chapter describes the metallic ore deposits of Chile, their mineralized host rocks and the processes involved in ore formation, and provides a brief overview of the mining history of this Andean copper-rich country. The ore deposits are ordered according to their respective economic importance. Thus, after mining history and a general introduction, Chilean porphyry copper–molybdenum

20.1 Metal Deposits Physical Geology

During the ore-forming process, some of the original minerals in these rocks are altered to potassium feldspar, biotite, epidote, and various clay minerals. The important ore minerals include chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4), and pyrite in copper porphyry deposits, or molybdenite (MoS 2) and pyrite in molybdenum porphyry deposits

Ore deposit geology Britannica

Uranium ores occur in deposits that are both near-surface and very deep (e.g., 300 to 1,200 metres, or 1,000 to 4,000 feet). The deep ores sometimes occur in seams as thick as 30 metres. As is the case with ores of other metals, surface uranium ores are readily mined

Important metallic deposits formed are Fe, Zn, Cu, Pb, Au and Ag. In the Red Sea metalliferous sediments containing Fe, Zn and Cu are being deposited. Mn oxide deposits are important at some ridges Eg the TAG Hydrothermal field on the Atlantic Ridge. Ultramafic rocks in ophiolites containing asbestos, chromite and nickel ores. These are generally accessible in Phanerozoic orogenic belts to

Quartz, calcite and pyrite constitute the common gangue minerals in most metallic vein deposits. Lengths and widths of veins are usually in the order of hundreds to thousands of feet in length, less than a foot to a hundred feet in width, up to several thousand feet in depth. Veins formed in the deep volcanic environment generally have good depth continuity of values, while those formed in the

For example, depletion of key elements in altered rocks, combined with measured or inferred estimates of the volume of altered rock, can constrain possible sources of ore metals. Finally, identification and recognition of hydrothermal alteration assemblages and their zonal relationships in the field may provide

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 borrowing costs

Economic geology Wikipedia

Study of metallic ore deposits involves the use of structural geology, geochemistry, the study of metamorphism and its processes, as well as understanding metasomatism and other processes related to ore genesis. [citation needed] Ore deposits are delineated by mineral exploration, which uses geochemical prospecting, drilling and resource estimation via geostatistics to quantify economic ore

Tectonic Settings of Metal Deposits Geology In

Ore Deposits and Plate Tectonics. P late tectonics, like crustal evolution, provides a basis for understanding the distribution and origin of mineral and energy deposits. The relationship of plate tectonics and mineral deposits is significant on three counts: Geological processes operating due to energy released at plate boundaries control the process of mineral deposition. Mineral deposits

Hydrothermal and Skarn Deposits

Often, feldspathoids and rare calc-silicates such as scapolite are found in more marginal areas. Skarns are sometimes associated with mineable accumulations of metallic ores of iron, copper, iron, zinc, lead, gold, and several others. In such cases these deposits are called "skarn deposits".

Ore Minerals and Precious Stones. Mineral exploration and mining involve the processes of searching and mining for the two kinds of mineral deposits, the metallic and nonmetallic ore deposits, as well as the precious stones. This is achieved by undertaking regional and detailed mineral exploration programs. The Saudi Geological Survey has paid great attention in intensifying mining works in
