    Rock magnetic parameters and bulk sample grain sizes were measured and analyzed in a loess section located in Bole, Xinjiang. The results show that magnetite and maghemite are the main magnetic minerals in Bole loess, and hematite and geothite were also detected; the magnetic minerals domain is of intermediate coarse PSD and MD, indicating weak pedogenesis. There is an excellent positive relationship between magnetic susceptibility and bulk sample grain size, which is opposite to the case of Chinese loess plateau, suggesting that magnetic properties are mainly controlled by allochthonous magnetic minerals. Magnetic susceptibility can be used as a proxy of wind velocity and loess sources changes. In different regions, the environmental significance of magnetic susceptibility is dissimilar. Therefore, great care should be taken when using susceptibility values for paleoclimatic reconstruction.
