Iron ore is primarily classified as a sedimentary rock. It forms through the accumulation of iron-rich minerals, often in sedimentary environments like lakes and oceans. Some iron ore deposits can also result from metamorphic processes, but the majority are sedimentary in origin, particularly those found in banded iron formations.

Is Coltan a mineral igneous rock metamorphic rock or sedimentary?
Coltan is an ore formed of columbite and tantalite and occurs in igneous rocks.
What type of rock is copper ore?
Copper ore is typically found in igneous rocks, such as basalt or granite, as well as in sedimentary rocks like shale. The most common type of rock where copper ore is extracted is called porphyry copper deposits, which are a combination of igneous and sedimentary rocks. These rocks contain copper minerals like chalcopyrite, bornite, and chalcocite, which are essential for copper extraction.
Is a peacock ore sedimentary?
Peacock ore, also known as bornite, is not sedimentary; it is an igneous or metamorphic mineral. It typically forms in hydrothermal environments through the alteration of copper minerals. Its vibrant iridescent colors are due to the oxidation of copper within the mineral. Thus, peacock ore is classified as a sulfide mineral rather than a sedimentary rock.
What are ore deposits sometimes found in?
Ore deposits are often found in geological formations such as sedimentary basins, volcanic regions, and metamorphic terrains. They can occur in various rock types, including igneous, sedimentary, and metamorphic rocks. Additionally, ore deposits may be associated with specific geological processes, such as hydrothermal activity, which can concentrate minerals, or through weathering and erosion, which can lead to the formation of secondary deposits.
Where is magntite found?
Magnetite is found in various locations around the world, including Sweden, Russia, and the United States. It is commonly found in igneous and metamorphic rocks, as well as in hydrothermal veins and as detrital grains in sedimentary rocks. Magnetite is also often associated with iron ore deposits.
What process did iron ore go through to be a sedimentary rock?
Orginally an igneous rock and then became secondary metamorphic rock and now sedimentary rock.
Is iron a igneous or sedimentary rock?
Iron, or Iron Ore, is a mineral that is found within rock. It would be more likely to be found in igneous rocks as a vein or ore to be mined. However, red sandstone has particles of iron ore within it, which give it the reddy colour.
Is Coltan a mineral igneous rock metamorphic rock or sedimentary?
Coltan is an ore formed of columbite and tantalite and occurs in igneous rocks.

Is coal an igneous rock?
Coal is a sedimentary rock. However, harder forms of coal, because of exposure to elevated temperature and pressure, are metamorphic rock.
Is sphalerite a sedimentary rock?
Sphalerite is not a sedimentary rock. It is a mineral that typically occurs in hydrothermal veins in igneous and metamorphic rocks. Sphalerite is a zinc sulfide mineral commonly found in ore deposits.
Which mineral has a metallic luster a black streak and is an ore of iron galena graphite pyroxene magnetite?
The mineral you are describing is magnetite. It possesses a metallic luster, a black streak, and is an important ore of iron. Magnetite is known for its magnetic properties and is commonly found in igneous and metamorphic rocks.
What is the name for a natural magnet found in the earth's crust?
The natural magnet found in the Earth's crust is called magnetite. It is a mineral composed of iron oxide and is known for its magnetic properties, making it one of the most important sources of iron ore. Magnetite can be found in igneous, metamorphic, and sedimentary rocks and plays a significant role in geological studies related to magnetism.
