山东苍山县兰陵铁矿矿体特征及变化规律研究

Study on Lanling Iron Orebody Characteristics and Variation Pattern in Cangshan County,Shandong

山东苍山县兰陵铁矿为新发现的超大型隐伏沉积变质型铁矿,对该区的钻孔资料进行分析可知:矿区垂向存在矿化富集带及无矿带;平均品位沿垂向变化不大,走向上中部存在矿化富集现象;沿走向,矿体厚度品位变化无规律性,沿倾向,-1200m以浅厚度品位呈负相关关系,-1200m以深厚度品位呈正相关关系。矿体平均品位总体变化幅度不大,沿倾向有向下延伸趋势。

The Lanling iron ore in Cangshan County,Shandong is a newly found super large hidden sedimentary metamorphosed deposit. Analysis of borehole data in the area has shown that vertically has existed mineralized enrichment zone and barren zone in the ore district. Average grade of iron ore changes not much vertically; along the strike in middle part has mineralized enrichment phenomenon. Along the strike,relationship between orebody thickness and grade has no rules to follow; along the dip,above-1200 m level,negatively correlated,below-1200 m level,positively correlated. Variability of overall orebody average grade changes not much,and has a trend of downward extending.
