Structural Origin of the Red-Ribbon Style Iron Ores in the Xinyu Iron Deposit, Central Jiangxi Province

摘要

In summary,field observations and detailed measurements suggest that the red-ribbon style iron-ore bodies in Xinyu iron deposit result from regional plastic flow and sausage bending,rather than fold superimposition.The Xinyu iron deposit,located in central Jiangxi Province,is one of the most important BIF-type deposits in China.It is hosted in the Late Proterozoic volcanicsedimentary rocks,which are composed of sericitechlorite pyhllite,magnetite-bearing chlorite phyllite or schist,magnetite quartzite,and schist(Yu et al.,1989;Zeng et al.,2011).The Xinyu iron orefield lies on the eastern side of the Wugong Shan uplift,to the north of the South
