On the Loess Plateau, three typical Holocene loess sections are investigated and sam-pled. Compositions of heavy minerals in all samples are distinguished under microscopy and their contents are semi-quantitively analysised. The content ratios of unstable miner-als to stable minerals are considered as the index to reflex the degree of weathering and pe-dogenesis. The results indicate that:1) The categories of heavy minerals in all samples are complex and diverse, and the dominant heay minerals (opaque miner...
