The '''Magnet Cove igneous complex''' is a small [[Igneous rock#Chemical classification|alkalic]] [[Ring dike|ring complex]] lying to the west of the town of [[Magnet Cove, Arkansas|Magnet Cove]] in [[Hot Spring County, Arkansas]].<ref name=force>Geology of Titanium-Mineral Deposits, Eric R. Force, Geological Society of America, 1991, {{ISBN|0-8137-2259-4}} [https://books.google.com/books?id=FF0x5gEwRosC&pg=PA42&dq=%22magnet+cove%22+arkansas&sig=wcZK-AqLJU7GSJ7vANWPb0fwXGw Google Books]</ref> It and the adjacent town are so named due to the existence of [[magnetite]] and the terrain being a [[Cove (Appalachian Mountains)|cove]], a basin-shaped valley.<ref>''Excursion through the slave states'', George William<br />
Featherstonhaugh, Harper, Texas, 1844 [https://books.google.com/books?id=CVAPAAAAYAAJ&pg=PA107&dq=%22Magnet+Cove%22 Google Books]</ref><br />
<br />
The complex is of [[Mesozoic]] age, intruded into [[Paleozoic]] sediments.<ref name=force/> Mapping was conducted by the geologists Erickson and Blade in 1963.<ref>Erickson, Ralph A. and L. V. Blade, ''Geochemistry and Petrology of the Alkalic Igneous Complex at Magnet Cove, Arkansas'', Geological Survey Professional Paper 425, 1963, USGS</ref> Units within the complex include [[carbonatite]], [[nepheline syenite]], [[phonolite]], and [[ijolite]]. <br />
<br />
In addition to the magnetite which forms both massive [[lodestone]] and crystals, the complex is strewn with odd and rare minerals, and is the [[type locality (geology)|type locality]] for five mineral species. Over 100 different minerals have been identified from the area.<ref name=Mindat>[http://www.mindat.org/loc-3407.html Mindat data and list of minerals]</ref><br />
There are many [[titanium]] minerals such as [[rutile]], [[anatase]], [[brookite]], and [[perovskite]], as well as some [[vanadium]] mineralization. Some [[Rare earth mineral|rare-earth-bearing minerals]] have also been identified. <br />
<br />
Many companies have mined the area over the last century, including the Diamond Jo Quarry.<ref name=Mindat/><br />
<br />
The complex has developed a unique soil series, Magnet, which has several inches of dark reddish brown loam over reddish brown clay or clay loam. The Magnet is present only over 5000 acres at the complex and a small outlier at [[Potash Sulphur Springs]].<ref>{{Cite web|url=http://casoilresource.lawr.ucdavis.edu/gmap/|title = SoilWeb: An Online Soil Survey Browser &#124; California Soil Resource Lab}}</ref><br />

[[Arkansas Highway 51]] runs generally east–west through Magnet Cove.<br />
