| 摘 要： | 碳酸盐矿物的阴极发光特征与其成分有关。笔者用阴极发光与电子探针微区分析法对砂岩中碳酸盐矿物进行测试分析 ,其结果表明碳酸盐矿物的阴极发光与微量元素含量有如下规律 :①碳酸盐矿物在铁含量高于猝灭下限或锰含量低于激活下限时 ,不具有阴极发光性 ;②铁的猝灭下限约为 0 0 4mol,锰的激活下限为小于 7× 10 - 5mol;③铁 /锰比值越高 ,越不利于碳酸盐矿物阴极发光 ;但是铁 /锰比值小于 1的碳酸盐一定具有阴极发光 ;④铁或锰二者之一含量很少时不利于碳酸盐矿物的阴极发光。

| Abstract: | Variations in the cathodoluminescent properties of the carbonate minerals in reservoir sandstones are usually attributed to differing properties of manganese as the most important activator, and iron as the main inhibitor of luminescence. The results of research on the cathodoluminescence and microprobe analysis in this study led to the following conclusions.(1)The cathodoluminescence will get dark when the carbonate minerals contain FeCO3 more than 0.04 mol, or MnCO3 less than 7×10-5 mol.(2) The higher the ratios of FeCO3 to MnCO3, the weaker the cathodoluminescence of the carbonate minerals.(3)The carbonate minerals must be cathodoluminescent when the ratios of FeCO3 to MnCO3 are less than 1.(4)The cathodoluminescence tend to disappear when the iron or manganese contents appromaxite to zero. |
