| Abstract: | Three kinds of amber from two mining sites in China have been measured by
the techniques of IR, ESR and NMR. Amber from Fushum mines in Liaoning
province has been estimated to be 50 million years old, and Xixia amber from He-
nan province is about 70 million years. It is evident that all specimens are well
preserved without any weathering. |
