The Southeast Missouri (USA) Proterozoic iron metallogenic province types of deposits and genetic relationships to magnetite-apatite and iron oxide-copper-gold deposits
The Southeast Missouri (USA) iron metallogenic province within the Mesoproterozoic St. Francois Mountains terrane includes eight major iron deposits and approximately 30 minor deposits. Three of the major deposits have been mined: Pilot Knob magnetite, Iron Mountain, and Pea Ridge. These deposits ha...

The Southeast Missouri (USA) iron metallogenic province within the Mesoproterozoic St. Francois Mountains terrane includes eight major iron deposits and approximately 30 minor deposits.
