Distribution and formation of magnetite2018-07-13
The mineral resources of the Antarctic region are very rich. As far as the identified resource distribution is concerned, the reserves of coal, iron and oil are the first in the world, and other mineral resources are also stored in varying degrees, and are under investigation. The Antarctic has discovered a region with the most diverse mineral resources, and humans can use these resources for research and development and production. The Antarctic continental Permian coal seam is mainly distributed under the ice sheet of Antarctica, with a reserve of about 500 billion tons.
Almost everyone knows that magnetite is an ordinary secondary mineral that is scattered in many igneous rocks. In some rocks, it is condensed by magma differentiation and forms a huge iron ore body. Some deposits often contain ilmenite. Perovskites often appear as large layered and lenticular ore bodies in metamorphic rocks. The world's largest magnetite deposits are Kiruna and Gliwo in Sweden, which are thought to be condensed from magma. Other important deposits are located in Norway, Romania, and the Soviet Union. Magnetite deposits available in the United States are in New York, Utah, California, New Jersey, and Pennsylvania. In North Minnesota, magnetite is the main mineral in low-grade iron ore-bearing quartzite.
China's magnetite is mainly distributed in Baotou in Inner Mongolia and Chenzhou in Jiangxi. It is a rare earth magnetite and the world's most powerful magnet, accounting for 80% of the world's rare earth. The Chinese government has now used rare earth materials very well. Pay attention to it, whether it is in industry or in life, it plays a vital role, showing the weight of rare earth!
