中文摘要:

      定量XRD方法经历了提出、发展与完善、融合与推广3个阶段，形成标样法和无标法两类方法。其中一些被应用到湖泊沉积上以挖掘矿物定量信息；而湖积物的复杂性又使得其存在误差大、耗时、费力等缺陷，也出现了各种改进方法，与其它手段整合似乎成为必然。但定量XRD方法在湖泊沉积与环境演化上的应用价值很大，极具发展空间。

英文摘要:

      Q-XRD methods have passed three stages （proposing, improvement, merging and spreading）, divided into standard methods and standardless methods. Some are applied to lacustrine mineralogy for quantitative data, with drawbacks such as big error, time-consuming, and labor intensive due to complex- ity of materials. So various improvements are tried and blending with other techniques is a trend. But q- XRD is valuable and continued to perfect in lacustrine mineralogy and environmental evolution.
