Metamorphic Rock Iron Ore

Metamorphic Rock Iron Ore. Of iron, formed the iron ore (hematite magnetite) in the metamorphic basement rocks. As a new target area, the region has a powerful potential. The uplifting of the metamorphic massif and related post metamorphic tectonics (possibly in Neo tectonic period) gave way the prominent channels for emplacement of

Hydrothermal and metamorphic fluid-rock interaction

Iron ore within the QF varies in terms of structural setting (low- vs. high-strain domain; Table 1), metamorphic grade of the country rocks (greenschist, amphibolite facies), host lithology (quartz-, dolomite- and amphibole-itabirite) and iron oxide mineralogy (magnetite, martite, granoblastic, microplaty, specular hematite and goethite; Table 1).

Hematite: A primary ore of iron and a pigment mineral

It is an iron oxide with a chemical composition of Fe 2 O 3. It is a common rock-forming mineral found in sedimentary, metamorphic, and igneous rocks at locations throughout the world. Hematite is the most important ore of iron. Although it was once mined at thousands of locations around the world, today almost all of the production comes from

Iron-rich sedimentary rocks Wikipedia

Iron-rich sedimentary rocks are sedimentary rocks which contain 15 wt.% or more iron.However, most sedimentary rocks contain iron in varying degrees. The majority of these rocks were deposited during specific geologic time periods: The Precambrian (3800 to 570 million years ago), the early Paleozoic (570 to 410 million years ago), and the middle to late Mesozoic (205 to 66 million years ago).
