| Abstract: | Mineral magnetic measurements as a newly developing methndolgy in lake sediment study, have proved to be of exceptional promise by virtue of their relative cheapness, ease of use, nondestructive nature and versatility. This paper gives a brief introduction on magnetic method and its environmental applications.As an example, the magnetic properties of the sedoment cores from Taihu Lake are used for sediment stratigraphy, core-core coorelation and environmental change indications, in comparison with geochemical, pollen and granulometric data. The results show that the magnetic measurement pro vides a useful and informative tool for the study of environmental change. |
