网页2021年12月1日 · The chemical analysis of the sediment confirms the presence of many minerals with varied concentrations. The studied sediment sites consist mainly of quartz, aragonite, montmorillonite, calcite, albite, microcline, and Muscovite, which were confirmed by FTIR and XRD results.
XRD-based quantitative analysis of clay minerals using reference ...
网页2018年3月1日 · Several quantitative methods based on XRD analyses for clay mineral quantification have been developed (e.g., the reference intensity ratio (RIR) method (Visser and de Wolff, 1964), the mineral intensity factor (MIF) method (Moore and Reynolds, 1997), the external standard method (Leroux et al., 1953), the no-standard method (Salyn and Drits ...
USGS Information Handout: X-Ray Powder Diffraction
网页XRD is one of the primary tools used to evaluate the lateral and vertical variations in mineral matter and major, minor, and trace elements in coal beds. These data are used to help determine the impact of geologic and geochemical processes on coal bed formation in order to understand and predict both inorganic and organic variability within ...
