【摘要】：石英膠結(jié)物是砂巖中重要的膠結(jié)物類型。用納米離子探針(CAMECA Nano SIMS 50L)對石英膠結(jié)物中Al、Ca和Mg等重要微量元素進行原位分析,可為成巖作用研究提供重要基礎依據(jù)。然而,由于缺乏相應的標準物質(zhì),一直不能對石英膠結(jié)物中Al、Ca和Mg進行研究。針對不均一的石英顆粒樣品,文中采用細磨、混合、高溫熔融(2000℃,6個小時)與快速冷卻等措施,制作均一化的石英玻璃。經(jīng)納米離子探針驗證,該石英玻璃中Al、Ca和Mg在亞微米尺度上是均一的,已能滿足成巖作用研究的需要。隨后,用電感耦合等離子體發(fā)射光譜和激光剝蝕電感耦合等離子體質(zhì)譜測定了石英玻璃中Al、Ca和Mg的含量。相對靈敏度因子分析顯示,這些測試結(jié)果是協(xié)調(diào)、合理的。該均一化的石英玻璃可作為亞微米尺度Al、Ca和Mg原位分析的標準物質(zhì)。
[Abstract]:Quartz cementation is an important type of cementation in sandstone. The in-situ analysis of some important trace elements such as AlnCa and mg in quartz cementation by (CAMECA Nano SIMS 50L can provide an important basis for the study of diagenesis. However, due to the lack of corresponding reference materials, it has not been possible to study Al ~ (2 +) Ca and mg in quartz cement. The homogeneous quartz glass was prepared by fine grinding, mixing, high temperature melting (2000 鈩，
