Numerical modeling of pore-fluid flow and heat transfer in the Fushan iron ore district, Hebei, China: Implications for hydrothermal mineralization

摘要: Abstract This paper uses the numerical method to simulate pore-fluid flow and heat transfer associated with iron ore-forming processes in Fushan ore district, Hebei, China. Since mineralization may last a long period of time hydrothermal system, it is commonly assumed, geochemistry, that solutions minerals are an equilibrium state or near state. The relationship between concentration temperature has been considered determine rate ore. Using FISH language FLAC code, coupled flow, have simulated first generic model, then actual geological model district. ion (Fe2 +) magnetite (in NaCl buffer) calculated using TOUGHREACT software can be used analyze precipitation pattern magnetite. results studies pore fluid considering enhance our understanding formation directly indirectly for mineral exploration.
