| Abstract: |
| In this study, we summarized the research progress on the application of the physical and chemical properties of aeolian quartz (e.g., grain size, morphology, electron-spin- resonance-signal intensity, crystallization index, content and flux, and δ18O) in provenance tracing and paleoclimatic reconstruction over the past decades and addressed several problems in its application. The results show that these indices of quartz are stable and can indicate the change of source and paleoclimate. The problems and suggestions we proposed are also of great significance for the future study of indicating paleoclimate change by quartz. |
