iron ore breccia

Breccia Wikipedia

Breccia (/ ˈ b r ɛ tʃ i ə / or / ˈ b r ɛ ʃ i ə /) is a rock composed of broken fragments of minerals or rock cemented together by a fine-grained matrix that can be similar to or different from the composition of the fragments.. The word has its origins in the Italian language, in which it means either "loose gravel" or "stone made by cemented gravel".A breccia may have a variety of

Iron oxide copper gold ore deposits Wikipedia

Iron oxide copper gold ore deposits (IOCG) are important and highly valuable concentrations of copper, gold and uranium ores hosted within iron oxide dominant gangue assemblages which share a common genetic origin. These ore bodies range from around 10 million tonnes of contained ore, to 4,000 million tonnes or more, and have a grade of between 0.2% and 5% copper, with gold contents ranging

Iron Ore ~ Learning Geology

The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items. It is the most-used metal by both tonnage and purpose.

Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil ".

Sedimentary Rocks | Pictures, Characteristics, Textures, Types

There are three basic types of sedimentary rocks. Clastic sedimentary rocks such as breccia, conglomerate, sandstone, siltstone, and shale are formed from mechanical weathering debris. Chemical sedimentary rocks, such as rock salt, iron ore, chert, flint, some dolomites, and some limestones, form when dissolved materials precipitate from solution.

Hydrothermal breccias in vein-type ore deposits: A review

(2) Mapping quantitative geometric breccia parameters could be used as a new tool in exploration. For example, the transition from hydraulic to collapse breccia in fluorite–barite deposits coincides with the root of the ore shoot (Jébrak, 1984b). This could be expressed by measuring the morphology of fragments in the veins; and
