| Abstract: | 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 minerals, epidoteand hornnlende) are almost the same. However, some differences in contents are noted, especially in contents of unstable miner-als.2) The F value is susceptible index of degree of weathering and pedogenesis.3) From the view piont of pedogenics, the Hei Lu Tu soil has given rise to different natural weathering conditions and human actions, the profile of Hei Lu Tu is a multi-pro-file. |
