封面故事：由赤铁矿构成的富铁矿石。在新疆东天山哈密小红山地区黄沙漫漫的戈壁滩, 王登红等发现致密块状的猪肝色铁矿石可围成一圈, 外径约 1.5 m, 形似一棵大树的树桩, 判断其为“铁化木”(与硅化木对等)。附近还有不少绛红色带圈状构造的块状铁矿石散落四处, 其中还有不少“人”字形纵向近平行的白色石膏脉, 判断为泥沼型铁矿石。无论是“铁化木”还是泥沼型铁矿石, 其Fe2O3的含量均在60%以上, 最高达83.38%, 属于名副其实的“富铁矿”, 但并没有磁性！这项由中国地质科学院 矿产资源研究所王登红研究员取得的研究成果, 详见本期第570-580页。（图片提供：王登红）
Cover Story：Rich iron ores are composed of hematite. In the gobi desert in the Xiaohongshan area of Hami in the East Tianshan Mountains of Xinjiang, WANG Deng-hong discovered dense, massive red-brown (the color of pig liver) iron ores, forming a 1.5 m outer diameter circle, like the stump of a large tree; these were judged to be “ironwood” (equivalent to siliceous wood). This discovery also includes massive, magenta, ring-structured iron ores scattered around the ironwood, with several groups of herringbone-shaped vertical, nearly parallel white gypsum veins in the ores. These ores are judged to be bog-type iron ores. However, regardless of whether it is ironwood or bog-type iron ore, its Fe2O3 content is more than 60% (up to 83.38%), indicating “rich iron ore”. Interestingly, this iron ore is not magnetic. The research achievement was led by Professor WANG Deng-hong, Institute of Min-eral Resources, CAGS. For details, see pp. 570-580 of this issue.
