During systematic investigation on the typical profiles of the Late Quaternary in the Lushan region, the authors collected quartz samples from the profiles. The samples were sieved into particles with quartz particle size of θ= 1～3mm. Observation under electronic microscope reveals quartz microstructures such as morphology, deformation, and dynamic chemical effect. Key events taking place in the process were analyzed to understand environmental response of strata profiles. Through comprehensive index which reflects earth surface process and environmental response, four paleo-climate environmental stages were determined from bottom to top：glacier environment, inter glacier environment, ice margin environment to post glacier environment. The research results provide new evidence for further study and understanding of evolution and global change of the Quaternary environment in the Lushan region.
