| 摘 要： | 铬铁矿是金伯利岩型金刚石矿床含矿性重要指示矿物之一.通过对山东蒙阴金刚石矿区无矿、贫矿、中等含矿、富矿金伯利岩岩筒中的铬铁矿红外光谱系统采集，寻找不同金伯利岩岩筒中铬铁矿红外谱图参数特征与金伯利岩含矿性的关系，以达到判断金伯利岩体无矿、贫矿还是富矿的目的.不同含矿性金伯利岩岩筒中50个铬铁矿红外光谱参数特征统计显示：铬铁矿红外光谱A峰吸光度与高频峰吸光度平均比值从无矿、贫矿、中等含矿到富矿金伯利岩岩筒，数据依次为0.71、0.73、0.83~0.93、1.09，显示出明显的找矿指示意义.

| Abstract: | Chromite is one of the key indicators for ore potentiality of kimberlite type diamond deposits. With systematical collection of infrared speetra of the ehromites from kimberlite pipes in the Mengyin diamond orefield in Shandong Province, the infrared speetroseopie features of the ehromites in barren, poor, medium-ore-bearing and rich ores are respectively analyzed, to find out their relation to the ore potentiality of the kimberlite. The statistic results show that, from barren, poor, medium-ore-bearing to rich ores, the average ratios of absorbanee of A-peak and high-frequeney peak of the infrared spectra are 0.71, 0.73, 0.83-0.93 and 1.09, respeetively, with a significant indieation. |
