On the distance science review of the Lushan region, the particular researched for the geologic stratum section of Late Quaternary Period in the Lushan Dajiaochang area. This introduced or with the ancient terrestrial magnetism, and electronics spin resonance (ESR) and 36Cl, and luminescence dating etc. of various instrument of the dating method are analysis, they constituted the whole geologic strata of the complete section from the series age data that since 400 Ka.B.P., there be opposite to with it identified out the Biwa-III (320 Ka.B.P.) event, and the Biwa-II (260 Ka.B.P.) event, and the Biwa-I (180 Ka.B.P.) event (the molest influence of the iron dish is scarcity), and the Blake (100 Ka.B.P.) event, and the Laschamp (20 Ka.B.P.) event (the activity influence of the surface layer is not growth) etc. of events of ancient terrestrial magnetism. That also combined the layer sequence geologic strata and the layer type characteristics and sink to cumulate the sediment environment, by early to night for thedivided to 4 developmentic gyrational stages the section geologic strata: the I stage is climate period of the glacial epoch (400~200 Ka.B.P.), the II stage is climate period of the interglacial epoch (200~100 Ka.B.P.), the III stage is climate period of the glacial marginal epoch (100~10 Ka.B.P.), the IV stage is climate period of the post glacial epoch (10~0 Ka.B.P.).
