Linfen basin is the most important fault basin in Shanxi fault zone,it provides important evidence for researching global change. The drilling rock core from the Guo Jianzhuang section was analyzed for determination of magnetization rate and grain degrees,and compared with other typical profile. The result showed that deposition environment of Linfen basin in Mid-late Pleistocene was that the upper layer belongs to loess deposition and lower layer belongs to river-lake phase deposition. The climate in whole Linfen basin experienced four cycles of warm wet-cold. Magnetization rate and grain showed changes with depth and different deposition environments,and appeared different climate phenomenon compared with paleo climatic proxies from Xifeng section.
