同步辐射X射线荧光微探针测定岩石中的元素分布
Determinations of the Element Distributions in Granite-Hypersthene by SR XRFM
【摘要】 同步辐射X射线（白光）荧光微探针在大气环境下,光斑尺寸为（50×50）μm2,位移为1mm/步,计数时间30s,扫描测量了含石榴石紫苏花岗岩中多元素（K、Ca、Ti、Cr、Mn、Fe、Cu、Zn、Rb和Sr）的分布并绘制成图。检测限达x×10ppm,绝对量为10-10—10-11g范围。
【Abstract】 The elements in granite-hypersthene were measured by SR X-ray(white) fluorescence microprobe with beam spot of (50 × 50)μm2. The counting time was 30s. The distance between two neighboring spots was 1mm. All measurements were carried out under atmosphere. Maps of elemental distributions were drawn. Detection limits were n×l0ppm (or 10-10-10-11g).
