Abstract：Soils from Earth's surface record critical evolution information on climate,environment and human since the Quaterna-ry.Soil is regarded as one of the most important carrier for studying the past geological history.The soil properties,such as ion transformation,grain size distribution,mineral content and composition,are closely related to the coeval climate and environ-ment variation.Some properties are extracted as weathering proxies,which are widely used to reconstruct the past climate his-tory.In this study we focused the climatic significance,research methods and case studies of the authigenic mineral proxies—clay minerals and Fe-oxide minerals,and review their advantages and limitations in reflecting weathering degrees and climate conditions.Clay minerals and Fe-oxide minerals can be used as independent weathering and climate proxies.However,the ap-plicability is conditioned by geological background,provenance,climate type,etc..Besides,a multi-proxy method is preferred in regional weathering and climate reconstruction.
