【摘要】:石英胶结物是砂岩中重要的胶结物类型。用纳米离子探针(CAMECA Nano SIMS 50L)对石英胶结物中Al、Ca和Mg等重要微量元素进行原位分析,可为成岩作用研究提供重要基础依据。然而,由于缺乏相应的标准物质,一直不能对石英胶结物中Al、Ca和Mg进行研究。针对不均一的石英颗粒样品,文中采用细磨、混合、高温熔融(2000℃,6个小时)与快速冷却等措施,制作均一化的石英玻璃。经纳米离子探针验证,该石英玻璃中Al、Ca和Mg在亚微米尺度上是均一的,已能满足成岩作用研究的需要。随后,用电感耦合等离子体发射光谱和激光剥蚀电感耦合等离子体质谱测定了石英玻璃中Al、Ca和Mg的含量。相对灵敏度因子分析显示,这些测试结果是协调、合理的。该均一化的石英玻璃可作为亚微米尺度Al、Ca和Mg原位分析的标准物质。
