【摘要】 利用中子活化对鄂尔多斯盆地油气田上方的地质样品进行了某些元素的检测,通过实验分析,得到了该地区岩石中某些元素的含量,并对该地区的放射性元素作出了评价,绘制了样品的稀土配分模式图和评价了当地的金属矿产资源情况。结果表明,在油气田的上方,放射性元素铀呈现出负异常;钍和钾无明显异常;岩石中的其它元素和中国大陆地壳元素丰度基本接近,没有明显的金属矿产异常。更多还原

【Abstract】 The experiment used the method of neutron activation analysis of geological samples in the Ordos region has done a certain element detection.Through experimental analysis,the content of some elements in the region’s rock was got,the environmental radioactivity in the region to make an evaluation,mapping of distribution pattern of rare earth in different samples and evaluation of the local metal mineral resources.The results show that the radioactive level of the region had no significant radioactive anomalies,rock elements and China close to the earth’s crust element abundances,there is no obvious abnormality of metal ores.更多还原
