Application of Sediment Chromaticity in Paleo-Environment Reconstruction

Global environmental evolution studies involving millennia, centuries, decades, and interannual time scales have received increasing attention from scholars. Improved resolution of these time scales for paleo-environmental reconstruction has become increasingly popular, especially paleo-environmental reconstruction performed using high-resolution data. For reconstructing the paleo-environment using high-resolution data, many researchers are opting to use chromaticity an environmental proxy. This paper reviews the use of chromaticity for paleoclimate reconstruction of lake sediments, ancient loess soils, deep-sea sediments and coastal sediments. The paper also discusses the role of chromaticity in sediment tracing, determining advancement and retreat of glaciers, astronomical cycles, uplift of Qinghai-Tibet Plateau, circulation of Westerlies, and its application in the new research fi eld of paleo-earthquakes. Lastly, the paper explores the application of chromaticity in geology.
