锶与碳酸盐岩中不溶残余物关系的探讨

Study on Relationship Between Sr and Insoluble Residues in Limestone

对德国南部法郎垦地区２个上侏罗统碳酸盐岩系列剖面逐层采集了２０４个样品，并用Ｘ射线荧光光谱法进行了锶元素质量分数的测定．结果表明，该元素的质量分数分布范围在０．００５％～０．０３７％之间锶质量分数与碳酸盐岩中的酸不溶残余物图解中存在一个最大值区域；陆源物含量及原始沉积物中文石与方解石比例与锶元素在石灰岩中的丰度有密切关系．

samples are sampled from two carbonate rock profiles of upper Jurassic in Fran Conian Alb area, South Germany. The samples are tested for Sr by X ray fluorescence spectrum and the result shows that the mass fraction of Sr ranges from 0.005% to 0.037%. In the diagram of Sr and insoluble residues, there exists an area where the maximum value of Sr lies. The amount of land source material and the ratio of aragonite to calcite in primitive sediments are closely related to the abundance of Sr in limestone.
