Geological Theories and Prediction Studies on Iron-Rich Ore Formation
Iron ore is an extremely important mineral resource that underpins the development of the national economy and society. The characteristics of China's iron ore endowment are: few rich deposits and many poor ones; a predominance of medium- and small-sized deposits, with very few ultra-large deposits; and numerous associated components, resulting in unfavorable beneficiation and smelting conditions. “ The 12th Five-Year Plan ” During this period, the focus of geological and technological research on iron ore has been centered on the fundamental theoretical issue of the ore-forming mechanisms of high-grade iron ores. To tackle this challenge, national resources were mobilized to carry out intensive research efforts, with particular emphasis on studying the formation mechanisms of high-grade iron ores in sedimentary-metamorphic, skarn, volcanic, and magmatic vanadium-titanium magnetite deposits. Additionally, research was conducted on iron isotope theory, iron ore dating techniques, and iron ore deposit prediction methodologies. As a result, a series of innovative insights have been gained, providing crucial theoretical support for guiding exploration activities aimed at discovering high-grade iron ore deposits.
I. Major Scientific and Technological Innovations
1. A new understanding of the geodynamic background for the formation of iron-rich ores has been proposed.
It is believed that the geodynamic setting for the formation of iron-rich ore deposits in the Panxi mineral concentration area involves mantle plume activity and the involvement of lithospheric mantle. In a closed system, primitive picritic magmas enriched in iron and titanium underwent fractional crystallization, thereby giving rise to iron-rich deposits. Fe-Ti The basic parental magma (PanZhiHua pluton) subsequently led to ore formation. The Tarim Large Igneous Province shares similarities with the Panxi region.
