High-resolution cyclostratigraphic analysis of multiple climate proxies from the Permian-Triassic boundary in deep-water environment of the Dongpan section, South China
A chemical database was used to reconstruct the depositional environment and to investigate the influence of high frequency Milankovitch cycles on the chemical composition of the sediments in south China.A high-resolution analysis of multiple climate proxies from a rhythmic Upper Permian and Lower Triassic succession, where sedimentological, paleontological, and geochemical data suggest stable depositional conditions,yields information on the pace and nature of paleoenvironmental changes. Three strong peaks in the results of spectral analysis of these chemical data for this interval (bed 2 to bed 15) appear to correspond to Milankovitch frequencies in the eccentricity, obliquity and precession bands.
